The best water-sports forecast apps in 2026

The best water-sports forecast app depends on your sport. Surfline is strongest for surfers who want live cams, Windy for people who read weather models themselves, Windguru and Windfinder for wind-sport forecast tables, and 4Shor for a 0–100 score across 10 sports and 4 ability levels in Europe. A surfer chasing groundswell wants different things from a kitesurfer watching the sea breeze, or a paddleboarder waiting for a glassy morning. (Full disclosure: we make 4Shor. We've tried to be fair about where the others are stronger — because that's the only kind of comparison worth reading.)

What is the best surf forecast app?

For surfing alone, Surfline is the standard: its biggest edge is live cams at hundreds of spots worldwide, a deep global surf-spot database and a long-refined swell forecast. For checking whether it's actually breaking right now, nothing beats a live cam. Surfline also absorbed Magicseaweed in 2023, consolidating much of the English-speaking surf world into one platform.

The trade-off: it's built around surfing. If you also kite, wing, windsurf, paddle or swim, you're back to reading raw wind and tide yourself. And a cam tells you about now, not which of the ten beaches in your range will be best at 6pm.

Is Windy a good wind prediction app?

Windy is the best weather visualiser there is, and a strong wind prediction app for people who like to read the picture themselves. Windy.com offers animated maps of wind, swell, gusts and pressure, and lets you flip between models (ECMWF, GFS, ICON and more). It has global coverage and a generous free tier.

The catch is that Windy hands you data, not a decision. It won't tell you whether 18 knots cross-onshore at your local beach is a good beginner kite day or a washing machine — that judgement is left entirely to you.

Are Windguru and Windfinder good for kitesurfing and windsurfing?

Yes. Windguru and Windfinder are the long-standing favourites of windsurfers and kitesurfers, giving clean, spot-based forecast tables of wind speed, gusts and direction, sometimes with multiple models side by side. Both are fast, cheap and trusted. Windguru's dense tables in particular are a rite of passage for the wind community.

Like Windy, they're raw-number tools. They excel at wind but say little about how a wave will actually break at a specific reef or sandbar, and there's no per-ability read on whether a given day suits a beginner or an expert.

How is 4Shor different from the other forecast apps?

4Shor starts with the physics and then gives you a 0–100 score for 10 sports at 4 ability levels, refreshed hourly. We've built our own high-resolution map of the nearshore seabed for the entire European coastline, and for every location we model how the wave refracts, shoals, focuses and breaks over that specific bathymetry, layered with national high-resolution weather models and tides.

Most apps apply a generic offshore reading to a pin on a map; 4Shor models the wave that actually breaks at the spot.

The 0–100 score is the output of that model, not the point of it. The same beach can read 78 for a beginner on a small, clean day and 34 for an expert wanting power, because a good day depends on who's asking. But the number only means something because of what sits under it: real nearshore wave physics, run on real, high-resolution seabed data. A score built on rubbish inputs is just a rating; this is a decision grounded in physics (the full pipeline is here).

Coverage is Europe-focused (2,500+ locations), it spans surf and wind and flat-water sports in one place, and today's conditions are free on the web. What it doesn't (yet) have: live cams, or coverage outside Europe.

So which forecast app should you use?

Use the app that matches your sport: Surfline if you only surf and want live cams, Windy or Windguru/Windfinder if you like reading models and wind tables, and 4Shor if you do more than one sport and want a straight answer on where to go today in Europe. For a quick side-by-side, see the full feature comparison. In short:

• Surf only, want to see it live: Surfline, for the cams and spot database.
• You love reading models yourself: Windy, or Windguru/Windfinder for wind-specific tables.
• You do more than one sport, ride at a mix of abilities, and want a straight answer on where to go today in Europe: that's exactly what 4Shor is for.

Honestly, most people end up using two: one to visualise the weather, and one to make the call. For the call, see today's live scores on any location page, or start with a sport — surfing, kitesurfing or wing foiling. New to the jargon? The glossary has you covered.
