Windy
Reading the weather models. Raw model data for every sport — no judgement, no per-ability score.
BEST EFOIL FORECAST APP
The best e-foilingforecast app?
Windy, Windguru are all good at what they do. Here's a fair look at where each wins for e-foiling — and where a per-ability, physics-grounded score fits.
eFoils are powered, so the usual wind and swell forecasts are the wrong tool — you want the flattest, calmest water, which apps like Windy and Windguru are not built to score. 4Shor scores eFoiling for calm: light wind and low chop rank highest, so you can find the glassy window rather than read around a wind map.

Reading the table
Every tool here is genuinely useful — they're built for different jobs. Windy is reading the weather models; Windguru is wind sports — quick tables.
What only 4Shor does for e-foiling: 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 e-foiling 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 e-foiling. Here's the honest read on what each is best at, and the gap a per-ability, physics-grounded score fills.

WHAT MATTERS
What to look for in a e-foiling 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 e-foiling, 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 e-foilingforecast 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 e-foiling score per ability, from the seabed up. See the full method or the e-foiling conditions guide for the ideal-conditions breakdown.
FAQ
E-Foiling forecast app — common questions
What's the best e-foiling forecast app?
eFoils are powered, so the usual wind and swell forecasts are the wrong tool — you want the flattest, calmest water, which apps like Windy and Windguru are not built to score. 4Shor scores eFoiling for calm: light wind and low chop rank highest, so you can find the glassy window rather than read around a wind map.
Is 4Shor a good alternative to Windy for e-foiling?
Windy is strong for reading the weather models. 4Shor's edge for e-foiling is the per-ability 0–100 score built from nearshore wave physics: Ideal eFoiling is flat, glassy water and light wind — the board is powered, so it wants calm rather than swell or breeze; sheltered bays on a still morning are prime. Many riders use both — one to read the raw conditions, 4Shor to decide where to go.
Does 4Shor score e-foiling 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 e-foiling spots.
What data does 4Shor use for the e-foiling 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 e-foiling score is built from.
How many e-foiling spots does 4Shor cover?
More than 2,500 coastal locations across Europe, each scored for e-foiling 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 e-foiling forecast?
Yes. Today's e-foiling 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 e-foiling alerts before a good day?
Yes. 4Shor can push an alert when a spot crosses your e-foiling 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.
