Frequently asked questions

Windmaster is a wind and wave forecast built for kitesurfers, windsurfers, wingfoilers, and surfers. For hand-picked spots around the world it combines a calibrated multi-model forecast, live wind from nearby stations, real tides, and gear-size guidance — so you can quickly decide whether it's worth heading out.

Yes, the core of Windmaster is free: you can browse every spot, the calibrated Masterforecast, and the 16-day outlook without paying or even signing in. A free account adds saved spots and gear-size recommendations. Windmaster Pro is an optional subscription that unlocks every forecast model, the 6-hour live-wind trend, and wind alerts.

No, you can browse spots and forecasts without signing in. A free account lets you save spots, sync them across your devices, and set up a rider profile for gear-size recommendations. Wind alerts and the full multi-model forecast are part of Windmaster Pro.

Yes. Windmaster is available as a native iOS app on the App Store. It also works in any mobile browser, where you can add it to your home screen.

It's our headline forecast. Instead of showing one raw weather model, we route to the model that performs best for each region and then apply a per-spot calibration learned from real measurements. The result is a number tuned to what actually happens at that spot — not just generic model output.

We work hard to make them realistic, calibrating against live station data wherever we have it. But wind is local — especially at venturi and thermal spots like Tarifa, where the real wind can run well above or below the models. Treat the forecast as a strong guide, cross-check it against the live wind reading, and use your own judgment on the beach.

Forecast data comes from Open-Meteo. On the outlook you can compare GFS, ECMWF, and ICON directly, while the Masterforecast picks and calibrates the best fit per region.

You get a detailed, calibrated 3-day forecast plus a 16-day outlook, and the data refreshes hourly.

Where a nearby weather station is available — currently parts of the Netherlands, Spain, and France, with more coming — we show its most recent real-world reading next to the forecast, so you can see what the wind is doing right now.

Live wind only appears when there's a nearby station with a recent reading. If the closest station is too far away, offline, or its data is stale, we hide the live card rather than show you a number we don't trust.

Search by name or coordinates from the top of any page, or browse the curated catalog by sport and by the best months to go.

Yes. With an account you can save spots and reorder them, and your list syncs automatically across every device you sign in to.

Opt-in push notifications that tell you when one of your saved spots is forecast to hit rideable conditions, matching both wind strength and the right direction, in the countries you've enabled. Wind alerts are part of Windmaster Pro.

Yes. Surf spots surface swell-focused information — wave height, period, and swell direction — with a surf-specific verdict, alongside the wind data the other sports rely on.

We add curated spots continually, but you can also search any location by name or coordinates to pull up a forecast for it.

Pro is our optional subscription. It unlocks every forecast model (cross-check ECMWF, GFS, and ICON, including ECMWF on the live map), the 6-hour live-wind trend from the nearest station, and wind alerts for your saved spots. The core forecast, the Masterforecast, the 16-day outlook, saved spots, and gear recommendations stay free.

Free: browse every spot and forecast, the calibrated Masterforecast, the 16-day outlook, and the live wind reading. With a free account you also get saved spots and gear-size recommendations. Pro adds every forecast model, the 6-hour live-wind trend, and wind alerts.

Pro comes as a monthly or annual plan, and annual saves the most. New subscribers can start with a 14-day free trial: you won't be charged until it ends, and you can cancel anytime before then. The exact price for your region is always shown on the upgrade screen before you confirm.

In the iOS app your subscription is billed by Apple: cancel anytime in iPhone Settings under your Apple ID, then Subscriptions. On the web, manage or cancel from your Account page. Either way you keep Pro until the end of the period you've already paid for.

Yes. Pro follows your account, not the device. Sign in with the same email on the web and your Pro features unlock there too, and the same works the other way around.

On a new device, open the upgrade screen in the iOS app and tap Restore. Make sure you're signed in with the same Apple ID and the same Windmaster account you originally subscribed with.

Only what you give us: your sign-in email, an optional rider profile (gear, body stats, skill, all optional), and the spots you save. If you subscribe to Pro, we also keep your subscription status, never your card number. We don't sell your data or use it for advertising. Full detail is in our Privacy Policy.

Sign in, open your Account page, and tap Delete account at the bottom of the Profile section. Deleting your account removes all of your data — profile, saved spots, and settings — immediately and permanently.
