Scores combine swell, wind, tide and bathymetry. Today is free for everyone — the next 7 days at hourly resolution live in the 4Shor app.
Most forecast apps stop at swell + wind. 4Shor goes the extra mile by modelling how the near shore seabed and coastline transforms those inputs — refraction, shoaling, dissipation, focusing, breaking — into the wave you'll actually meet at this exact spot.
Satellite derived bathymetry with 10 m pixels. 10 cm vertical resolution out to ~40 m depth.
Multi-source ocean swell data provides a 24-direction × 30-frequency spectrum at the offshore boundary every hour.
Near shore wave model propagates the spectrum across the bathymetric mesh — refraction, shoaling, dissipation, focusing, breaking.
10 sport models × 4 ability levels weight wave / wind / period / tide differently — calibrated against ridden sessions.
Playa de Montaña Amarilla is one of more than 2,500 European locations in the 4Shor library. We model how waves will break at this exact piece of coast — combining bathymetry, swell, wind, tide, man-made and natural water obstacles— so you don't have to interpret raw data to know whether it's on.

The coast can change fast. A blown-out afternoon here can be a glassy session half an hour down the road. The nearest 4Shor-scored spots, same model, different conditions — so you can pick the one that's actually firing today.
For sure it is! We have done extensive testing and refinement of the forecast models and conditions scores to provide results that you can have confidence in.
If you surf, foil, paddleboard, swim or anything in between — and want to know exactly what the conditions will be like for you — then yes, 4Shor's for you. 🌊
Current forecast apps only provide swell, wind and tide data and in many cases expect you to do the analysis yourself. 4Shor goes the extra mile — we model how waves will break and build that into our forecasts to allow us to create conditions scores for your chosen water sport and skill level – something that no other app does.
4Shor combines satellite-derived bathymetry (fancy word for underwater mapping), advanced wave models with wind and tide data to generate precision, hyper-local forecasts.
We're starting with the most popular breaks and launch locations across Europe and new locations are being added all the time. So it is likely that we're already mapping the best locations on your coastline. If your location isn't included yet, give us a shout and we'll add it to our roll out.
Yep. No tricks, no card up front. You get full access for 7 days on us. After that, you can decide if the sessions saved are worth the price of a post-surf burrito.
Absolutely. Whether you're chasing your first green wave or doing your first kitesurf body drag, 4Shor helps you choose the right place at the right time for your sport and ability. Think of it as a smart local who knows when it's mellow enough for learning and when it's time to sit on the sand and watch.
