The most granular weather data in the world

There are a lot of weather APIs out there – and they all use the same public sources of weather data. ClimaCell has the only weather API that uses proprietary sensing technology to deliver the best (and fastest) ground-level weather data in the industry, with the best nowcasting model.

5 Ways the Climacell Microweather API is Different

New Sensing Tech

Traditional weather companies rely on public weather sources like government radar. ClimaCell is the only one that takes the best of existing weather technology and adds new sensing technologies that find microweather™ that no one else can see.

Truly Ground Level

ClimaCell’s proprietary technology tracks weather closer to the ground that is often missed by traditional sources. This is why major airlines and sports teams rely on us — to make sure every storm is tracked.

Truly Hyperlocal

Everyone says they are hyperlocal, but ClimaCell’s Microweather™ API is the only one that can deliver weather data zoomed in to a specific location. With other APIs when you pick a location, you’re seeing weather from a large area around that location.

Fastest Updates

Other APIs may send you data every minute, but often that data is 5-20 minute-old radar data. ClimaCell’s GPU-powered technology delivers data updated to the minute.

Best Nowcasting

Most short-term forecasts look out in hour chunks into the future. ClimaCell’s Microweather™ API gives you what the weather will look like in every minute for the next 6 hours.
