Traeth Trearddur faces SW, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow kite surfing wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is cross-offshore at 7 kn. Leaning offshore, so a failure drifts you away from the beach rather than back to it — rideable for kite surfing, but not the direction to push your luck in.
Over the published window Traeth Trearddur clears 60/100 for kite surfing 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, 2 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.
This is a Blue Flag sandy bay, sheltered and gently shelving with soft golden sand, doubling as a hub for windsurfing, kayaking, dinghy sailing, bodyboarding, and jet-ski. The quite exposed beach break offers left and right waves, best on a SW swell with NE offshore wind, most consistent in winter; rips and submerged rocks are cited hazards. An RNLI inshore lifeboat station operates on-site year-round, and beach wardens control marine vessels.
