Joss Bay faces NE, so the prevailing westerly comes over the land before it reaches you. For kite surfing that usually means a gustier, less predictable flow than the raw wind speed suggests.
Today's wind is cross-shore at 7 kn. Straight cross-shore is the classic kite surfing direction: it lets you hold a line along the beach rather than fighting to get back to it.

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 north-east-facing bay of sand and chalk reef catching easterly and north-easterly swells other beaches miss, with a central beach break over shifting sandbars and reef lefts and rights on the flanks. A surf school operates here, and kitesurfers use it, staying offshore of the surf zone; reefs are shallow and hazardous at low tide, and rips are a hazard. RNLI lifeguards patrol daily in season. Dogs banned 1 May-30 September, except early and late.
