About this app

Boardiction works out where you'll have the most fun tomorrow.
Multi-model weather data, tuned to your spot, explained by AI in two sentences.
Your wind reports feed straight back into the model — you make the forecast better, for yourself and for everyone else.
SPOT-ACCURATE FORECASTS
We blend global weather models (ECMWF, GFS, ICON) with regional ones (Arome HD, Icon CH1) freshly for every spot. Which mix works on site is something the community's session feedback tells us. And where every model is blind, our machine learning steps in.
YOUR SPOT GETS BETTER BECAUSE YOU'RE THERE
A newly added spot starts with a well-founded estimate. With every wind report and every rating of a forecast it learns — and gets more accurate the more people ride there. You're not improving the forecast for us, but for yourself and everyone who sails the same lake.
WIND SHADOW
Our physics-based terrain model calculates, for every spot and every wind direction, how mountains, forests and buildings weaken the wind — so you know when a spot really works and when the forecast only looks good on paper.
HOW GOOD WILL THE SESSION BE
Instead of raw wind figures you see the best time window for each day and how good it will be — from "fair" to "epic". And because a day often has more than one window, morning thermals and an afternoon build-up, you get all of them.
What's waiting for you at the spot is explained by the AI in plain language — with a warning when things get tricky.
YOUR HOME WATERS ARE IN HERE
Ready-made forecasts cover spots in Germany, Austria, Switzerland, Italy, Denmark and Greece — Walchensee, Kochelsee, Tegernsee, Achensee, Silvaplana, Torbole and Malcesine on Lake Garda, Hvide Sande on the Danish coast, Limnos in the Aegean.
And if your spot isn't there yet: our catalogue reaches far beyond that, from Croatia through Slovenia and Cyprus to Portugal. You search for it, you add it — and from then on we compute it for you.
The focus is on thermal regions — where forecasting is hard and a good forecast makes the difference.
Every spot runs the Boardiction model that fits it best — and every rating of a forecast makes it better.
NEW REGION? SPOT RECOMMENDATION
No local knowledge, nobody to ask? Boardiction searches the area and recommends the spot that suits. You don't have to research it yourself any more.
TIDES IN VIEW
At tidal spots you see the tide right in the forecast, and the spot recommendation factors it in — so you turn up when both line up: wind and water level.
SPOT CHAT AND SPOT KNOWLEDGE
Every spot has its own chat: live conditions, session partners, local knowledge. The practical details are kept up by the community — height restrictions, entry points, showers, parking. From people who are actually there.
And the Boardies display shows you how busy a spot is before you set off. Check in at the tap of a button when you're on the water.
FOR YOUR SPORT
Windsurfer, kitesurfer, wing foiler — pick what you ride. Wind speed in knots, km/h, m/s or Beaufort, temperature in °C or °F. Light or dark. Your settings, your units.
FREE TO START
Boardiction is free to use: several spots, the full forecast with no delay, unlimited spot chat. No account needed to get going.
Boardiction Pro unlocks every spot and removes the ads.
Never miss a session.
One last note: Boardiction is a forecast, not a guarantee. Weather in the mountains and on a lake can turn quickly. Judge your own ability realistically, stay within your limits and follow the rules at your spot. Boardiction does not replace official weather warnings.
