Each location is refreshed once every three hours. The hourly view, 7-day forecast, luck factor and packing notes come from the same stored update.
We compare the 7-day forecast with the version-matched historical observations available for the same time of year at Caswell Bay. The delta shows whether conditions look better, worse or about the same as a typical late July.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

Caswell Bay is a sheltered, picturesque beach break located on the Gower Peninsula in South Wales. The bathymetry features a flat, compacted sandy gradient enclosed between two distinct limestone headlands. This geographical configuration heavily filters incoming wave energy; it requires a significant south-westerly groundswell pushing up the Bristol Channel to generate rideable surf within the bay itself. A north-easterly offshore wind provides the best surface conditions. When the swell successfully navigates the headlands, it dissipates over the shallow sand, producing soft, slow-rolling waves that lack steepness or hydraulic power. These extremely forgiving mechanics make Caswell Bay an ideal environment for beginner surfers. The spilling whitewater and gentle green faces offer ample time to establish balance, master the pop-up technique, and practice basic directional control. While the waves are largely insufficient for advanced shortboarding manoeuvres, the bay provides a highly safe, low-consequence venue for novices to build fundamental confidence in the ocean.
Heads up: jellyfish: high.

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.
The air here is 74% cleaner than the average comparison city right now.
Significantly cleaner air than a typical city. Ideal for outdoor exercise with minimal respiratory strain.
Not a pollutant. Ozone is naturally higher at altitude and near the coast, and lower in cities where traffic exhaust breaks it down. High readings here typically indicate clean air. Can cause short-term airway irritation during intense exercise but is not linked to the long-term health risks of particulate pollution.
Additive health score: each pollutant contributes points relative to its WHO 2021 guideline and long-term health impact (PM2.5 9, NO₂ 5, O₃ 3, PM10 2, SO₂ 1 at WHO limits). Data via Open-Meteo. City markers show live readings. Red line marks the WHO guideline. Updated 15:24

Combining historical conditions with school holiday crowd pressure to find the sweet spot.
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.
