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 custom models. Our next-generation Forecast On-Demand forecasting engine powers our Weather Data APIs.

Our architecture employs several 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

Professional weather monitoring system outdoors with sky behind it.

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 utilizes 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 forecast models are leveraged as input
The Weather Company’s proprietary models run at a higher resolution than government models and incorporate real time weather data from radar and satellite
