Halo blends 14 forecast models, live buoy readings and your own quiver into one session score per hour, so you rig up exactly when your spot comes alive.
Levante from 95° E, steady since 07:00 · gusts to 28 kn
Raw models tell you knots. Halo tells you whether those knots work at your beach, on your tide, with the kite already in your car.
Every hour gets one number from 0 to 10, weighing wind strength, gust spread, direction against the beach, swell and tide for the exact gear you ride.
Back-tested against 1.2 million logged sessions.
ECMWF, ICON-D2, AROME and eleven more, each weighted by how well it has called your spot over the last 90 days.
Hit rate within 3 kn: 87%
Swell height, period and tide state run on the same timeline as the wind, so you see when the sandbar actually works.
Tide stations linked: 1,140
Pick a spot, a minimum score and your quiver; Halo pings your phone or watch the evening before a window opens.
Average warning ahead of a window: 19 hours
Every other app said 14 knots at Valdevaqueros. Halo called a three-hour Levante window from 15:00. I left work early, rigged my 9 m at 15:10 and had the best session of my summer — it switched off at 18:20, ten minutes after the window closed.
Session alerts are the only notifications I keep on. One ping the night before and I know whether to load the foil boards.
The tide overlay finally showed why our club racing only works two hours either side of low water.
Rider and Club start with a 14-day trial, no card needed.
