Weather API for Weather Forecasts

API for Weather Forecasts

Our Weather Forecast API is based on high quality weather models. We optimize global forecasts to specific sites using Model Output Statistics. Our solar forecasts based on this methodology have earned top marks in benchmarks. For complex parameters such as wind fields or precipitation we rely on our own, fine-meshed mesoscale forecasting model WRF.

Typical applications of the weather forecasts API are:

  • Routing or timetable web applications that provide customers with a forecast on a specific location and time as added value
  • Control software for buildings, heaters, cooling etc. which optimize an installation taking into account the weather
  • Applications for the optimization of energy planning and energy trading, which require weather data for the forecast of production and consumption

Features:

  • Weather forecasts in hourly resolution
  • Forecast horizon up to 10 days in the future
  • Any locations (defined by place name, postal code or coordinates)
  • Worldwide coverage
  • Output format CSV, XML, JSON, YAML or as needed
  • Sums/averages of hourly values for 6, 12, 24 h possible
