1 Best APIs for Daily forecast in Nigeria

Weatherbit API is a reliable, developer-friendly weather data service providing current weather conditions, 16-day daily forecasts, 120-hour hourly forecasts, historical weather, weather alerts, and air quality data for any location worldwide via a clean RESTful API. Weatherbit is widely respected for its data accuracy, comprehensive endpoint coverage, well-documented API reference, and competitive pricing that makes it accessible to Nigerian startups and developers who need more than the OpenWeatherMap free tier offers but cannot justify premium AccuWeather pricing. The 16-day daily forecast horizon is one of the longest among mid-tier weather APIs, making Weatherbit particularly useful for applications that need extended agricultural or event planning forecasts. Current weather data from Weatherbit includes temperature, apparent temperature, humidity, dew point, wind speed and direction, wind gust, sea-level pressure, precipitation, snowfall (globally), snow depth, cloud coverage, visibility, solar radiation, UV index, air quality index, and a detailed weather description code. The weather description code system maps to a comprehensive set of condition descriptions covering sunny, partly cloudy, overcast, various rain intensities (light, moderate, heavy, freezing), thunderstorm types, fog, and dust/sand conditions — the last of which is directly relevant to Nigerian Harmattan season when dust and sand from the Sahara reduces visibility across the country's northern and central regions. Hourly forecasting extends 120 hours (5 days) in advance with full hourly weather variables, enabling granular short-term planning for weather-sensitive Nigerian business operations. Construction site managers can check hour-by-hour rain probability before scheduling concrete pours. Event coordinators can assess whether weather will clear by the 6pm start of an outdoor concert. Agricultural drone operators can identify the optimal spray window between rain events by examining the 5-day hourly precipitation timeline. The 16-day daily forecast is Weatherbit's extended forecast offering, providing daily minimum and maximum temperature, precipitation probability and accumulation, wind speed and direction, humidity, UV index, sunrise/sunset times, and weather description for 16 days ahead. Nigerian farmers planning crop cycle activities — planting, fertilizer application, harvest scheduling — benefit from the 16-day horizon which aligns with the two-week planning cycles common in smallholder Nigerian agriculture. Air quality data is available through Weatherbit's Air Quality API endpoint, returning PM2.5, PM10, SO2, NO2, CO, and O3 concentrations alongside AQI values derived from EPA standards. Nigerian environmental monitoring apps that also need weather data for context can combine Weatherbit's weather and air quality endpoints under a single API account, simplifying data source management. Weather alert notifications from Weatherbit cover severe weather warnings issued by official meteorological authorities. Nigerian alert platforms and emergency management apps can poll Weatherbit alerts for any Nigerian region and surface these official warnings to app users with appropriate geographic precision. Historical weather data from Weatherbit stretches back to 2010 with daily and hourly resolution, offering over a decade of Nigerian weather records for analysis. Nigerian agricultural research institutions, insurance actuaries calculating drought years, and climate analysts building weather-indexed products can use this historical archive. Weatherbit offers a free tier of 500 calls/day with access to current weather and 7-day forecasts. Paid plans start at $35/month for 50,000 daily calls with full access to all endpoints including historical data, 16-day forecasts, and weather alerts. Nigerian developers can start with the free tier and upgrade as usage grows.
