Grande Plage de Port-Louis faces SW, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow windsurfing wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is cross-shore at 5 kn. Straight cross-shore is the classic windsurfing direction: it lets you hold a line along the beach rather than fighting to get back to it.
Over the published window Grande Plage de Port-Louis clears 60/100 for windsurfing at every ability from Beginner to Expert — an unusually broad spot, which normally means a range of conditions rather than one narrow sweet spot. Today, 1 of 10 daylight hours clear that line at Intermediate.

Satellite-derived bathymetry with 10 m pixels and 10 cm vertical resolution out to ~40 m depth. The shape of the seabed is what determines where and how waves break.
Most apps run a single global model at 9–25 km. We blend regional NWP from national meteorological offices at 1.3–2 km — UK Met Office UKV, Météo-France AROME HD, ItaliaMeteo ICON-2I — with ECMWF IFS for the 8-day horizon. Finer resolution means the sea breeze, cliff funnelling and bay shadowing that changes everything for a session.
A nearshore wave model propagates the spectrum across the bathymetric mesh — modelling refraction, shoaling, dissipation, focusing and breaking as it goes. Most apps stop at swell + wind. We go further.
10 sport models × 4 ability levels weight wave height, period, wind, tide and breaking conditions differently — calibrated against ridden sessions so the scores mean what they say.
A sheltered, family-oriented sandy beach behind historic citadelle ramparts, facing SW and shielded from open swell, so it produces no meaningful surf. A designated kitesurfing zone and a water sports centre operate here. Beach cabins, a playground and disabled access are provided. Lifeguard cover runs in July and August. Dogs and smoking are prohibited. Tidal range is significant, so check tide state before entering the water.
