Weather APIs

Packages API Our recommended solution to integrate weather data in your application
meteoblue provides raw data as hourly, daily or monthly time series or TMY (Typical Meteorological Year) since 1984 with a spatial resolution of 30 km for the following variables:
- Solar radiation
- PV yield
- Sunshine
- Cloud cover
- Temperature and dew point temperature

Maps API Fully customizable integration of our stunning weather maps
With the Maps API you can get access to innovative weather maps that cover the whole world with a wide range of weather data overlays, including temperature, precipitation, pressure and many more. Furthermore, the Maps plugin offers stunning animations for wind, satellite images and weather radar.
For Solar Energy purposes we recommend the following layers:

Images API Ready to use Weather and Climate diagrams
meteoblue offers thousands of images from different categories, that can easily be integrated. These images can be individually customised as they are available in many languages for any location on Earth.

Dataset API The big data API for complex analyses of historical weather data
To assure the highest quality level of your required radiation data we can compare satellite observed radiation data with other datasets like ERA5 reanalyses or weather models. The different datasets can be used to assess typical and extreme years and optimise long term yield.
history+

Year comparison
Visualise several seasons with accumulated precipitation or growing degree days (GDD) in one graph. See how a wet or rather hot season may affect plant development, calculate a heating sum to predict how much energy is required during winters or estimate weather conditions for a single week to plan events.

Histogram
history+ includes online analysis tools for frequency patterns. Temperature, precipitation and wind frequencies are visualised in a histogram and help to better understand occurance of conditions such as frost or intense precipitation.
