A wide, fine-sand urban beach in the town centre, facing SSW and partly sheltered by the harbour pier, which filters heavy Atlantic swell into milder, longer waves suited to longboarding and beginner surfing. Swimming and surf zones are kept separate. Kitesurfing and land-sailing are prohibited here. A quicksand area on part of the beach is closed off. At very high spring tides the sand can disappear almost entirely, concentrating waves near the seawall.

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 uses ShorSense™ — our coastal intelligence engine that combines satellite-derived bathymetry (fancy word for underwater mapping), advanced wave models with wind and tide data to generate precision, hyper-local forecasts.
