Caswell Beach

Nestled along the coast, Caswell Bay is a compact, scenic beachbreak that delivers shifting peaks over a sandy bottom, offering both left and right-hand rides. It’s a fickle setup, though—clean conditions are a rare luxury, and the bay needs a healthy dose of swell just to show its face. Don’t expect it to hold much size; once the waves push past head-high, the bay quickly devolves into a series of closeouts. The west end almost always holds the better shape, so aim your paddle there when the tide and wind align. This spot is best suited for surfers who don’t mind waiting for the magic window—and are ready to move when it arrives.

Best Surf Season (November - February)

Caswell Beach is at its best when the North Atlantic storm machine is firing. From November through February, average swell heights sit in the 4-5ft (1.2-1.6m) range and average periods stretch to 9-10.7s, giving this south-facing Gower beach the power and consistency it lacks in summer. Most of the energy arrives as WSW/W groundswell, but the SSE through SW sector is much better represented in winter, and that direct southern angle is what Caswell needs. Depending on the phase of the NAO, the storm track can either stay zonal and bring the classic UK W/SW soup or bend south and deliver more S/SE angled swell. The real filter is wind: only 12-15% of the time blows offshore from N/NNW, usually behind cold fronts, so the best sessions are short, cold and precious. With water cold and air often near freezing, this is committed winter surfing, but it is also the most rewarding time of year.
