About This Forecast

This forecast is powered by WeatherMesh, the world's most advanced and accurate weather model powered by AI. WeatherMesh is built on proprietary data from WindBorne's Global Sounding Balloon constellation — the world's largest fleet of autonomous, long-duration weather balloons — collecting observations across 100% of Earth, including over oceans and remote regions where no other data exists.

WeatherMesh consistently outperforms legacy models in independent benchmarks. View Benchmarks →

How to Access Weather Forecasts

PatternExampleDescription
/weather/{country}/{city}//weather/united-states/san-francisco/City forecast (canonical URL)
/weather/{city}//weather/tokyo/Shorthand — redirects to most populous match
/weather/{country}/{region}/{city}//weather/united-states/california/san-francisco/With region — redirects to canonical
/weather/nearby?lat={lat}&lon={lon}/weather/nearby?lat=48.1&lon=11.5Find nearest city by coordinates
/weather/{country}//weather/germany/Country index — all cities by region

Country and city names use lowercase slugs with hyphens (e.g. united-states, san-francisco). Arbitrary city names are supported — if not in our database, we geocode the name and serve the forecast for that location.

For programmatic access, use theWindBorne Forecast APIwhich returns structured JSON for any coordinates worldwide.
