8 Best APIs for Weather Data in Nigeria

OpenWeather Air Pollution and UV API is a specialized subset of the OpenWeatherMap platform that provides real-time and forecast air quality data including pollutant concentrations, Air Quality Index values, and UV index measurements for any location worldwide. As air quality concerns grow in Nigerian cities driven by vehicle emissions, industrial activity, open burning, and seasonal Harmattan dust storms, this dedicated air quality and UV data endpoint enables Nigerian health apps, environmental platforms, and smart city projects to integrate pollution monitoring features beyond standard weather data. The Air Pollution API returns concentrations of major pollutants: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2), fine particulate matter (PM2.5), coarse particulate matter (PM10), and ammonia (NH3). Each pollutant reading is given in micrograms per cubic meter, and the response includes an overall Air Quality Index (AQI) on a 1-5 scale (1=Good, 2=Fair, 3=Moderate, 4=Poor, 5=Very Poor). Nigerian health tech developers building pollution alert apps can use these granular pollutant readings to give targeted advisories — for example, warning asthma patients specifically when NO2 and PM2.5 are elevated, which is common near Lagos highways and industrial areas. Historical air pollution data is available through the Air Pollution History endpoint, allowing retrieval of past pollution levels for any location with a Unix timestamp range. Nigerian researchers studying the relationship between air pollution episodes and respiratory disease hospitalizations, or environmental lawyers building evidence of industrial pollution near communities, can use this historical endpoint to retrieve pollution records spanning months or years. UV Index data from the UV endpoint returns current UV Index value and time of day, along with daily forecast UV Index maximum and hourly UV progression through the day. UV radiation levels in Nigeria are high year-round due to the country's equatorial location, with UV Index values frequently reaching 8-11 (Very High to Extreme) during midday hours. Nigerian health apps promoting skin cancer awareness, outdoor workers' safety apps, and tourism platforms can integrate UV Index data to advise users on sunscreen application and shade-seeking during peak UV hours. Forecast capabilities of the Air Pollution API extend 5 days into the future with 3-hourly pollution forecasts for any location. Nigerian event planners organizing outdoor festivals or sports events can check forecast air quality before finalizing dates, and Nigerian health authorities can anticipate poor air quality episodes in advance to issue proactive public health advisories. During Harmattan season (November to March), when Sahelian dust dramatically elevates PM10 readings across northern Nigeria, the pollution forecast capability is particularly valuable. The Air Pollution and UV API uses the same OpenWeatherMap API key as the standard weather endpoints, making it easy for Nigerian developers already using OpenWeatherMap for weather data to add air quality and UV features without any additional registration. The free tier includes 1,000 calls/day shared across all OpenWeatherMap endpoints, and the air quality endpoints count toward this shared daily limit. Paid plans increase call limits and are priced the same as the broader OpenWeatherMap subscription, making it cost-efficient to bundle weather, air quality, and UV data under one account. Nigerian developers already on OpenWeatherMap can enable air quality and UV data immediately with no additional API key setup required.

FarmData Nigeria is a local agritech data platform providing agricultural datasets, farm records management, and research-grade data services specific to Nigeria's farming landscape. The platform aggregates farm-level data, crop yield records, soil information, and agricultural statistics from Nigeria's diverse agroecological zones to support agritech applications, agricultural research institutions, development organizations, and government agencies that require Nigeria-specific agricultural data for their programs and products. Nigeria's agricultural data landscape has historically been fragmented and sparse. National agricultural surveys are conducted infrequently, farmer record-keeping is minimal, and the spatial detail of available datasets is often insufficient for farm-level applications. FarmData Nigeria addresses this gap by building a continuously updated repository of Nigerian agricultural data through farmer engagement programs, partnership data collection, and integration of secondary sources including government statistics, remote sensing products, and academic research. The farm records component of the platform provides Nigerian agritech applications with a backend data management service for storing and retrieving farmer profile data, field boundaries, historical crop production records, input purchase records, and harvest outcomes. For Nigerian agritech companies that want to build farmer profile systems without developing their own data storage infrastructure from scratch, FarmData Nigeria offers a Nigeria-optimized data model that reflects the structure of Nigerian smallholder farm operations. Agritech developers building digital financial services for Nigerian farmers — input credit, savings products, agricultural insurance — need farmer profile data that captures production history, land holdings, and crop choices. FarmData Nigeria's farmer profile data, collected and verified through field programs, can support credit scoring models and insurance underwriting processes that base decisions on actual agricultural track records rather than proxy financial indicators. Research institutions — including Nigerian universities, the International Institute of Tropical Agriculture (IITA) with its major presence in Ibadan, and international research programs focused on African agriculture — can access FarmData Nigeria's dataset to support crop improvement research, agricultural economics studies, and development impact evaluations. Having access to nationally representative Nigerian farm data through an API reduces the research data collection burden and enables studies at scales that individual research programs could not achieve through independent field surveys. Government agencies responsible for agricultural statistics and planning — including the National Bureau of Statistics, the Federal Ministry of Agriculture and Rural Development, and state Agricultural Development Programs — can use FarmData Nigeria's farmer-level data to supplement and validate official agricultural surveys, enabling more frequent and spatially detailed updates to national agricultural statistics than are possible with traditional survey-only approaches. For Nigerian commercial agribusinesses — large-scale commodity traders, input companies, agricultural banks, and processing firms — FarmData Nigeria provides structured access to data about production patterns, farmer practices, and geographic distribution of crops across Nigeria. This data supports procurement planning (estimating available supply volumes in different regions), product targeting (identifying farmer segments for new input products), and expansion planning (understanding where specific crops are concentrated). The platform's Nigeria-specific data focus distinguishes it from global agricultural data providers that may have limited on-the-ground data for Nigeria. Data collected through FarmData Nigeria's local field programs reflects actual Nigerian farming conditions — the specific varieties grown, the input practices actually used, the market channels actually available — rather than model-based estimates derived from regional averages that may not capture Nigeria's agricultural diversity accurately.

Farmonaut is a precision agriculture and supply chain traceability API platform that provides satellite-based crop monitoring, field health analytics, supply chain tracking, and sustainability intelligence for agricultural enterprises, commodity traders, food companies, and agritech developers. The platform combines satellite imagery processing with agricultural AI to deliver crop condition insights and blockchain-based supply chain traceability that helps agricultural businesses optimize field operations and demonstrate sustainability to downstream customers. Satellite-based crop monitoring through Farmonaut registers farm fields as geographic polygons and delivers automatic NDVI, EVI, and other vegetation index time series as satellite imagery becomes available for registered locations. This automated monitoring approach allows agritech companies to build crop health monitoring products without managing satellite data pipelines — Farmonaut handles image acquisition, processing, and index calculation, delivering results through an API that agricultural applications consume. For Nigerian commercial farms managing large cultivated areas — rice paddies in the Niger Delta and Kebbi State, cassava and maize operations in the middle belt, tomato and vegetable production in Kano and Kaduna — satellite-based field monitoring makes the scale of regular field assessment feasible that would require impractically large scouting teams using only ground-based methods. NDVI maps of entire farm blocks delivered through Farmonaut identify problem areas for targeted investigation rather than requiring uniform scouting across the entire area. Yield prediction capabilities within Farmonaut use multi-temporal vegetation index data combined with weather variables and crop growth models to estimate likely harvest yields weeks before harvest occurs. For Nigerian food processing companies, commodity traders, and exporters planning logistics for crop offtake — arranging transport, storage, and export documentation — early yield estimates for specific farm areas they source from allow more efficient planning than waiting until harvest is complete. Supply chain traceability is a differentiated capability of Farmonaut that connects satellite field monitoring with blockchain-based documentation of the crop's journey from farm to market. For Nigerian agricultural exporters supplying food companies in Europe or North America that require supply chain transparency documentation — increasingly mandated by regulatory frameworks like the EU Deforestation Regulation — Farmonaut's traceability features provide the field-level geospatial documentation needed to demonstrate that sourced crops come from legitimate farm locations and not deforested land. The EU Deforestation Regulation (EUDR), which requires that covered commodities (including cocoa, oil palm, and coffee — all produced in Nigeria) imported into the EU must not have contributed to deforestation after December 2020, requires supply chain participants to provide geospatial information and due diligence documentation for sourcing locations. Farmonaut's field mapping and monitoring capabilities provide Nigerian cocoa and palm oil supply chain participants with the geospatial farm record documentation that EUDR compliance requires. Carbon sequestration and sustainability monitoring is an emerging use case for Farmonaut's satellite monitoring capabilities. As voluntary carbon markets develop and agricultural carbon credit programs expand in Africa, Nigerian farming operations that can demonstrate sustainable practices — conservation agriculture, agroforestry, reduced tillage — through satellite-verified monitoring create the documentation basis for carbon credit verification. Farmonaut's time-series vegetation data provides an objective, satellite-based record of land use practices that carbon verification methodologies can reference. Farmonaut provides API access with SDKs for common programming languages, enabling Nigerian agritech developers to integrate satellite monitoring and traceability features into their applications without managing the underlying Earth observation infrastructure. The REST API structure with JSON responses follows standard patterns accessible to developers familiar with web API integration, and documentation covering field registration, image retrieval, index calculation, and traceability record management makes integration straightforward.

EarthDaily Agro is the precision agriculture data intelligence platform from EarthDaily Analytics, providing field-level crop monitoring, agronomic analytics, and agricultural intelligence derived from high-frequency, high-resolution satellite imagery. EarthDaily Agro is designed for agribusinesses, commodity trading firms, agricultural insurance companies, and agritech developers that require enterprise-grade crop intelligence for operational decisions involving significant financial stakes. The satellite data foundation of EarthDaily Agro is the EarthDaily Constellation — a network of small satellites operating in low Earth orbit designed to image the Earth's entire land surface at 3-5 meter resolution daily, cloud permitting. This daily imaging cadence is a step change from the 5-16 day revisit typical of government satellite constellations like Sentinel-2 and Landsat. For agricultural monitoring where crop stress, pest outbreaks, and weather events can dramatically change field conditions within days, daily satellite imagery means that problems are detected much faster than with weekly or biweekly revisit systems. Vegetation monitoring products from EarthDaily Agro deliver NDVI, EVI, and NDWI at field level with daily temporal resolution where cloud cover allows, providing near-real-time crop health tracking. For Nigerian commercial farms where management teams need to act quickly on crop stress signals — ordering irrigation, dispatching spray equipment, alerting field staff to investigate — daily satellite monitoring dramatically reduces the lag time between a crop problem developing and the monitoring system detecting it. Field-level analytics in EarthDaily Agro aggregate satellite observations into actionable field health metrics rather than requiring users to interpret raw imagery. Crop stress indexes, phenological stage indicators (estimating where in the crop growth cycle a field currently is based on vegetation index time series shape), and yield potential indicators provide farm managers and agronomists with synthesized intelligence that directly informs management decisions without requiring remote sensing expertise. For Nigerian large-scale commercial farming operations — the rice estates in Kebbi and Niger States, large maize and soybean operations in the middle belt, plantation-scale oil palm in Rivers and Cross River States — EarthDaily Agro's enterprise monitoring capabilities match the scale and sophistication of operations where precision management decisions can affect many thousands of hectares and the associated commodity value. Daily monitoring at this scale is economically justified by the production values at risk and the management improvements precision data enables. Agricultural commodity trading firms sourcing Nigerian agricultural products use EarthDaily Agro for crop condition intelligence that informs procurement strategy. Understanding crop health and yield outlook for major sourcing regions during the growing season allows traders to make informed decisions about forward contract volumes, delivery scheduling, and price discovery — weeks before harvest outcomes become publicly visible through production reports. This information advantage has direct financial value in commodity markets. Agricultural insurance underwriting and claims assessment is a high-value use case for EarthDaily Agro's daily satellite monitoring. Insurance companies offering yield-based or damage-based agricultural insurance to Nigerian farmers can use satellite monitoring to assess crop condition continuously throughout the insured period, identify claims-worthy events (drought stress, flooding, pest damage patterns visible from space) objectively, and support or challenge claim submissions with satellite evidence. This objective, cost-effective claims assessment approach reduces both fraudulent claims and legitimate claims that are denied due to inability to verify damage at scale. Supply chain deforestation compliance — required for agricultural commodity exporters under the EU Deforestation Regulation — benefits from EarthDaily Agro's continuous monitoring capability. For Nigerian cocoa and palm oil supply chains subject to EUDR, high-frequency satellite monitoring of source farm locations provides the continuous observation record needed to demonstrate that no deforestation occurred at or around sourcing locations throughout the monitoring period.
