Weather updates every 20 minutes.
Forecasts that move as fast as the market.

Most models update 2–4 times a day. WeatherMesh ingests real-time observations from our balloon constellation, satellites, and ground stations to produce a full ensemble refresh every 20 minutes. No stale cycles. Just the most up-to-date forecast on the planet that gives you the earliest signals on every shift.

Why Traders use WeatherMesh

WindBorne Atlas, our global sensing constellation, is delivering the critical observations that are closing the atmospheric data gap.

WeatherMesh is built for moments where minutes matter — wind ramps, precipitation onset, temperature deviations, congestion risk, and regime shifts. Our advantage comes from two things no one else has:

Real-Time AI Data Assimilation

WeatherMesh uses a custom AI DA system that integrates new observations every cycle — not every 6–12 hours. Read more about our AI DA methodology here

WeatherMesh is built for moments where minutes matter — wind ramps, precip onset, temperature deviations, congestion risk, and regime shifts.

Accuracy You Can Verify

Delivers top-tier skill and you can check it out yourself. See our published and third party verified benchmarks.

Built by ML Engineers and Meteorologists
