Open-Meteo
Open-Meteo is a fully free and open-source weather API that provides high-resolution global weather forecasts, historical weather data, and climate projections without requiring any API key for non-commercial use. Built on top of state-of-the-art numerical weather prediction (NWP) models from ECMWF, GFS, Meteo France, DWD, and other meteorological agencies, Open-Meteo delivers hourly and daily weather variables across the globe with up to 16-day forecast horizons and access to decades of historical weather records. For Nigerian developers building weather-dependent applications who want a zero-cost starting point, Open-Meteo is one of the most capable free weather APIs available. Forecast data from Open-Meteo covers a wide range of weather variables: temperature at 2 meters, apparent temperature (feels like), precipitation, rain, showers, snowfall (unlikely in Nigeria but globally relevant), cloud cover, wind speed and direction at multiple heights, wind gusts, surface pressure, relative humidity, dew point, visibility, shortwave solar radiation, and cape (Convective Available Potential Energy for thunderstorm prediction). For Nigerian agricultural apps, the combination of precipitation forecasts and solar radiation data is particularly valuable for irrigation scheduling and solar energy production forecasting. The API returns data in hourly or daily resolution, selectable per request. Hourly data enables fine-grained analysis of weather through the day — important for Nigerian logistics operations planning around Lagos or Abuja rush-hour weather, or for event managers checking window-by-window rain probabilities for an outdoor concert. Daily data provides simplified summaries including max/min temperature, precipitation sum, sunrise/sunset times, and UV index maximum — ideal for Nigerian travel apps showing week-ahead weather summaries. Historical weather data through Open-Meteo is available from 1940 to the present via the Historical Weather API endpoint, sourced from the ERA5 reanalysis dataset by ECMWF. Nigerian climate researchers, agricultural historians, and developers building data analytics tools for climate trend analysis can access decade-long weather records for any location in Nigeria including remote northern and southern regions without subscription costs. This historical depth rivals expensive commercial weather data providers. Marine forecasting is supported through a separate marine endpoint returning wave height, wave direction, wave period, swell height, and ocean surface temperature — relevant for Nigerian fishing communities, port operators in Lagos and Apapa, and oil and gas companies operating in the Gulf of Guinea. The marine data combined with standard atmospheric forecasts gives a complete picture of weather-related conditions for offshore and coastal Nigerian operations. Air quality forecasting from Open-Meteo includes PM2.5, PM10, ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide concentrations, UV index, and European and US Air Quality Index calculations. Nigerian urban health apps monitoring air quality in Lagos (which has significant vehicle and industrial air pollution) can use the air quality forecast to send pollution warnings and health advisories to users. Climate projections through the Open-Meteo Climate API provide future temperature and precipitation projections from CMIP6 climate models, allowing comparison of projected future climate against the historical baseline. Nigerian policy researchers and environmental NGOs can use these projections to model climate change impacts on Nigerian agriculture, water resources, and urban heat islands. Open-Meteo is free for non-commercial use with no API key required — just call the endpoint with latitude, longitude, and the desired weather variables. Commercial use requires a subscription which remains affordable at under $50/month for most volumes. The API is highly reliable, well-documented, and used by thousands of developers worldwide, making it a strong foundation for any Nigerian weather-aware application.
Agromonitoring (Agro API)
The Agromonitoring Agro API is a satellite-based crop monitoring and agricultural weather API developed by the OpenWeather team, providing farm field monitoring through satellite imagery analysis and integrated meteorological data. The platform is specifically designed for agritech developers and precision agriculture application builders who need to combine satellite vegetation health monitoring with weather intelligence in a single API integration, covering registered farm field polygons across Nigeria and globally. The Agro API centers on a field polygon management system: developers register farm field boundaries as GeoJSON polygons through the API, and the platform automatically monitors those fields with available satellite imagery, computing vegetation indices and weather observations for each registered location. This automated monitoring eliminates the need for agritech developers to manage satellite data pipelines, handle image processing, or schedule individual imagery requests — the platform handles all of this automatically for registered fields. NDVI (Normalized Difference Vegetation Index) is the primary crop health metric delivered by Agromonitoring. NDVI values derived from satellite imagery measure green vegetation density and are directly related to crop biomass and canopy health. For Nigerian farms monitoring maize, cassava, rice, sorghum, or vegetable crops, seasonal NDVI time series track the crop growth curve from emergence through canopy closure and eventually senescence. The Agro API provides NDVI statistics — mean, minimum, maximum, and standard deviation — for each registered field at each available satellite observation date. Beyond NDVI, Agromonitoring provides EVI (Enhanced Vegetation Index) and NRI (Normalized Red Index) for crop condition assessment. EVI is less sensitive to atmospheric effects and soil background than NDVI, making it more reliable in conditions with high aerosol loading — a consideration for northern Nigerian zones where harmattan dust can affect optical satellite observations. Providing multiple indices allows Nigerian agritech developers to select the most appropriate measure for their specific crop monitoring context. The satellite imagery underlying Agromonitoring's vegetation indices comes from Landsat-7, Landsat-8, Sentinel-2, and MODIS constellations, providing a range of spatial and temporal resolution options. Sentinel-2's 10-meter resolution and approximately 5-day revisit provides detailed field-level monitoring with high temporal frequency. Landsat's 30-meter resolution and 16-day revisit offers coarser but longer historical coverage. MODIS at 250-500 meter resolution provides rapid updates for broad-area monitoring. Applications can access imagery from multiple sensors through the same API, selecting the sensor appropriate for each monitoring need. Weather data integration within the Agro API provides agricultural meteorological intelligence for each registered field location: current conditions, hourly and daily forecasts, and historical weather records. Precipitation data, temperature, wind speed, humidity, and solar radiation are available for field coordinates, enabling correlation of crop health observations with weather history and providing agricultural decision support that goes beyond vegetation index monitoring alone. Soil data endpoints within Agromonitoring provide estimated soil temperature and soil moisture for field locations, derived from models that combine weather observations with soil property information. For Nigerian farmers making planting timing decisions or irrigation management choices, soil condition data alongside crop health monitoring provides a more complete agronomic picture than either data type alone. For Nigerian precision agriculture companies building commercial farm management products, Agromonitoring provides a cost-effective API starting point with a free tier that covers limited field area, allowing proof-of-concept development and early customer pilots without initial API costs. As commercial scale grows, paid tiers accommodate larger field portfolios and higher API call volumes. The OpenWeather backing provides confidence that the platform has stable commercial infrastructure and developer support resources that align with the needs of Nigerian agritech companies building products they intend to scale.
