Flagship venues
CFD flow modelling
The airflow over the venue's real terrain, solved cell by cell for every wind direction — so the map shows where the breeze bends, funnels and goes light.
Venue-specific wind intelligence
Not a global weather app. Squall builds a wind model for each venue — shaped by its own terrain and shoreline, checked against its own stations, and at flagship venues solved with CFD.
Not a weather app
A generic forecast gives you one number for a grid cell kilometres across. Squall models the wind across your race area — where the hills shelter it, where the shore bends it, where the pressure fills in. We curate every venue, so you don't have to.

Every venue
Forecasts reshaped to the hills, headlands and shoreline around the water — sheltering, funnelling and the shift along a shore.
Every venue
Leading global and regional forecast models, weighted for each venue by how well each one has done there.
Every venue
Checked against buoys and stations near the course. Gusts are learned from those stations, not guessed from the model.
