Local knowledge and community tips for Caswell Bay
Caswell Bay is a sheltered cove on the Gower Peninsula in south Wales, tucked between limestone headlands. The bay faces south and picks up whatever swell manages to push up the Bristol Channel. It is predominantly a soft, forgiving wave that works well for beginners and improvers. The beach is golden sand with rock pools at either end. A pleasant, scenic spot that rarely offers serious surf but delivers fun small waves.
Requires a large south-westerly groundswell to wrap into the bay. A north-easterly offshore wind cleans things up. The headlands filter out most of the raw power, so you need a big swell running to get waist-to-chest-high waves in here. Best between October and March. On big storm days when Llangennith is maxing out, Caswell offers a sheltered alternative.
The middle of the bay has the gentlest slope and softest waves, ideal for beginners. The sections closer to either headland can produce slightly steeper peaks when the swell is bigger. On rare good days, a right-hander forms off the rocks on the east side.
Very safe overall. The sandy bottom is forgiving, the waves lack real power, and the bay is sheltered from wind. Rock pools at the edges can be slippery. On the rare occasion it gets above head high, currents form along the cliff edges. Swimmers and families share the beach in warmer months.
Pay car park at the top of the hill with a short walk down a steep path to the beach. Gets full in summer with beachgoers. Toilets and a small shop at the car park level.
Surf schools use Caswell as a sheltered teaching spot, so expect foam boards on any swell. Rarely crowded with actual surfers because the wave quality is limited. On the rare solid days, a few Gower locals will appear but it never gets competitive.
Caswell is a genuine fallback spot, not a destination. If the swell is big enough to work here, Langland (five minutes east) will probably be better with more defined reef peaks. However, if you are learning or want a gentle session without the crowd, this is the place. The ice cream van in the car park is a Gower institution.

Based on historical weekly averages
Combining historical conditions with school holiday crowd pressure to find the sweet spot.
How busy each week is based on school holiday overlap from feeder markets.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.

We compare the 7-day forecast to the last 5 years of marine data for the same week at Caswell Bay. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical mid-June.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
The best week for surf at Caswell Bay is the week of 23 November (score 3/5) with low crowds.
