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.

Distance

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

Timeliness

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

Content features

Our platform gives you access to a robust set of comprehensive weather data sources, with a scalable usage model customized to meet your needs.

Enhanced current conditions includes a Currents On-Demand solution, which is an observed conditions data set that covers the globe at a 4-kilometer resolution with select variables downscaled to 500 meters.

Enhanced current conditions includes:

  • Currents On-Demand observations
  • Personal weather station observation

Enhanced forecast

Use forecast models that are built by using leading-edge model forecasting enhanced by over 100 meteorologists; a network of observations from datasets such as radar and satellite assimilations; and AI- and ML-enhanced modeling capabilities.

Enhanced forecast includes:

  • Precipitation forecasts
  • 15-minute forecasts
  • 15-day hourly and daily forecasts

Historical weather data

Understand the impact of weather on your business and better manage future outcomes. Access a precise and accurate historical record of comprehensive weather data that includes hourly values for surface temperature, wind speed and direction, relative humidity, atmospheric pressure, and dewpoint. Includes historical weather data on-demand.
