Swansea Beach faces SE, away from the prevailing Atlantic swell. For surfing that means it needs a specific direction to work rather than picking up the everyday groundswell, so it is a spot to check rather than assume.
Today's wind is onshore at 10 kn. Onshore is the awkward one for surfing: it adds chop and pushes the wave over before it can stand up.
Over the published window Swansea Beach clears 60/100 for surfing at Beginner, Intermediate levels — that is who this spot is for on this sport. Today, 0 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Swansea Beach ranks 23rd for surfing. The order changes by discipline: the same conditions that put a spot top for one sport can drop it down the list for another.
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 wide, gently shelving sandy city bay: sand at high tide gives way to mud, rubble and mussel beds as the tide drops. Not a surf break — a flat-water spot for kitesurfing, stand-up paddleboarding and beginner windsurfing, designated a Watersports Centre of Excellence. A sewer outlet is marked by a post mid-bay; water quality worsens near storm drains after rain. No lifeguard patrol; entry is best around mid to high tide to avoid mud.
