Check Your Swimming Conditions

Use the 4Shor App to assess if you can swim

4Shor pulls raw meteorological data from the European Space Agency and national forecast organisations like the UK Met Office and Meteo France and integrates it with its own seabed data, which covers the shoreline down to about 15m, which most other forecasts miss. It is this seabed data that is critical because it is what shapes the offshore swell when it hits the shallower waters and how it eventually refracts, shoals and breaks near the shoreline. 4Shor’s forecasts for each location are scored against 4 ability levels for 10 different sports and weighted on each of the variables. This gives a single, easy-to-use score out of 100 that’s displayed here with the underlying data for those who want to see why.

Originally envisaged for surfing, wind surfing and kite surfing, the app now caters for swimmers too.


Live water-sports conditions by 4Shor

Matt Angell, 4Shor’s Chief Wave Scientist, says they started because of a fundamental question that founder Rich Brittan had after moving to Fuerteventura. This was “Why are the forecasts so often wrong?” So we set out to change the way that water-sports forecasts are done by first identifying and understanding what was missing, which it turns out was high-resolution mapping. For 20 years, “we’ve been solving mapping problems in some of the world’s toughest places and trying to answer the ‘so what’ and rather than just give clients rows and rows of numbers and charts, we always try to explain what is actually going on, and more importantly, why.”
