Weatherstack is a weather API that can provide meteorological data such as temperature, humidity, wind speed, precipitation, and forecasts. The exact data fields depend on the API's endpoints — check the documentation for a full list of available weather parameters. Many weather APIs also provide UV index, air quality, and severe weather alerts.
Historical weather data availability varies by API. Some weather APIs like Weatherstack offer historical records going back years, while others focus only on current conditions and forecasts. Check the API documentation to see if historical endpoints are available and whether they require a different plan or rate limit.
Weather API accuracy depends on the data sources the provider uses (e.g., government stations, satellites, radar). Short-term forecasts (1-3 days) are generally reliable across most weather APIs, while extended forecasts become less accurate. Weatherstack may source data from national weather services or proprietary models — see their documentation for details on data sources and update frequency.
Most weather APIs support lookups by geographic coordinates (latitude/longitude), city name, or zip code. Weatherstack likely supports at least one of these methods. Coordinate-based lookups tend to be the most precise. Check the Weather category for other weather APIs if you need a specific lookup method.
