Weather Data APIs for next-level applications

APIs curated to give you only what you need in the format you need it, including alerts, current conditions, forecast data, weather imagery, and more.

Effortlessly integrate reliable weather data

Recognizing the pervasive role weather plays in our lives, we’ve made it easy to integrate comprehensive weather data from the world’s most accurate forecaster1 into your applications, business processes, or your own custom models. Our Weather Data APIs are powered by our next generation Forecast On-Demand forecasting engine.

Our architecture employs a number of proprietary elements:

  • Patented system that synthesizes a suite of weather observation data
  • Proprietary forecast system that dynamically blends different model inputs based on real-time verification
  • Proprietary forecast system that integrates human forecast management to enhance accuracy
  • World-class uptime across The Weather Company data offerings

Dimensions of accuracy

Forecasts On-Demand are more accurate because of four foundational dimensions.


Forecasts On-Demand are exact and unique for the location needed.

  • Temperature forecasts on average, improve by about 2 degrees Fahrenheit
  • Precipitation forecasts improve by 15% with precise location forecasting


Forecasts On-Demand immediately begin using new data.

  • First day forecasts are updated 96 times per day (every 15 minutes)
  • Hourly forecasts for days 2-15 are updated 24 times per day

Expert influence

Forecasts On-Demand utilize a revolutionary approach to forecast management, enabling meteorological experts to leverage insights to enhance and steer the final forecasts.

Inputs and science

Current Conditions are provided at the most granular resolution of any weather provider.

  • Multiple forecasts models are leveraged as input
  • The Weather Company proprietary models run at higher resolution than government models, incorporating real-time radar and satellite data
