iWindsurf
Windsurfers — live wind. Live wind, not a session score — the call for your level is still yours.
BEST WINDSURF FORECAST APP
The best windsurfingforecast app?
iWindsurf, Windguru, Windy are all good at what they do. Here's a fair look at where each wins for windsurfing — and where a per-ability, physics-grounded score fits.
Windsurfers live in iWindsurf, Windguru and Windy — superb for raw wind strength, direction and gusts. What none of them do is judge the session for you. 4Shor weighs wind angle to the shore, gust spread and water state into one per-ability windsurf score, so you can see at a glance whether 20 knots cross-shore is a green light for your level.

Reading the table
Every tool here is genuinely useful — they're built for different jobs. iWindsurf is windsurfers — live wind; Windguru is wind sports — quick tables; Windy is reading the weather models.
What only 4Shor does for windsurfing: model how conditions actually behave at each spot on its own high-resolution European seabed map, then score that per sport and per ability. The 0–100 score is the output of real nearshore physics, which is why it can be read as a decision rather than a rating. See the full method, the windsurfing forecast across Europe, or the full app comparison.
THE FIELD
When each tool wins — and where it stops
Every app here earns its place for windsurfing. Here's the honest read on what each is best at, and the gap a per-ability, physics-grounded score fills.
When it wins When it wins Windguru
Wind sports — quick tables. Fast wind numbers — you convert them to a decision for your level.
When it wins Windy
Reading the weather models. Raw model data for every sport — no judgement, no per-ability score.
WHAT MATTERS
What to look for in a windsurfing forecast
The tools above hand you accurate numbers. The harder question is what separates a forecast you can act on from a table you have to interpret. For windsurfing, these are the things that actually decide the session:
- A decision, not just data. Wind speed, swell height and tide are inputs. What you want out is whether today is worth the drive — a single read, not four numbers to weigh in your head.
- Your ability, factored in. The same conditions are a green light for one rider and a write-off for another. A windsurfingforecast that ignores level is only half the answer.
- The spot's own seabed. How swell and wind behave in the last few hundred metres to shore — refraction, shoaling, shelter — changes everything. Open-ocean data misses it; nearshore modelling doesn't.
- Tide at this spot. Many places only work on a certain state or a push. A forecast that folds tide into the call beats one that leaves you cross-referencing a separate table.
- Enough warning. A good window is worth planning around, so horizon and alerts matter — you want to hear about the day before it arrives, not discover it that morning.
That's the frame 4Shor is built on: it turns the same modelled conditions into one 0–100 windsurfing score per ability, from the seabed up. See the full method or the windsurfing conditions guide for the ideal-conditions breakdown.
FAQ
Windsurfing forecast app — common questions
What's the best windsurfing forecast app?
Windsurfers live in iWindsurf, Windguru and Windy — superb for raw wind strength, direction and gusts. What none of them do is judge the session for you. 4Shor weighs wind angle to the shore, gust spread and water state into one per-ability windsurf score, so you can see at a glance whether 20 knots cross-shore is a green light for your level.
Is 4Shor a good alternative to iWindsurf for windsurfing?
iWindsurf is strong for windsurfers — live wind. 4Shor's edge for windsurfing is the per-ability 0–100 score built from nearshore wave physics: Ideal windsurfing is a steady 15–25 knots blowing cross-shore over manageable chop — strong enough to plane, angled so a rest still drifts you home. Many riders use both — one to read the raw conditions, 4Shor to decide where to go.
Does 4Shor score windsurfing by ability?
Yes. Every spot is scored 0–100 for Beginner, Intermediate, Advanced and Expert, so the same conditions read differently for a learner and an expert — updated hourly across 2,500+ European windsurfing spots.
What data does 4Shor use for the windsurfing forecast?
4Shor blends ECMWF and national weather models with its own high-resolution seabed map of the European coastline, then models how conditions actually behave in the last stretch to shore at each spot. That nearshore physics — not open-ocean data — is what the windsurfing score is built from.
How many windsurfing spots does 4Shor cover?
More than 2,500 coastal locations across Europe, each scored for windsurfing where the conditions suit it. Coverage is Europe-first, with 4Shor's own nearshore bathymetry for the European coastline rather than a thinned-out global grid.
Is there a free windsurfing forecast?
Yes. Today's windsurfing score is free on every 4Shor location page on the web, and the app gives you a free 3-day forecast. The full 8-day forecast and per-ability condition alerts are part of Premium and Pro.
Can I get windsurfing alerts before a good day?
Yes. 4Shor can push an alert when a spot crosses your windsurfing conditions threshold — tuned to your ability level — up to a week before the window opens, so you hear about the good days rather than checking a table every morning.
