The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, I gotta be straight with you: the next two weeks are a tough stretch for Three Peaks. For the first week and a half, nearly every day is a write-off. There’s a period from now all the way through to about the 25th of September where the conditions just keep letting us down. We’ve got a bit of a swell running, with chest to head high waves on a few days, but the wind is just relentless, mostly onshore or cross-onshore, trashing every chance of a clean wave. The combination of swell energy is moderate at best, and the surf quality is poor by local standards.
The first chance of anything worthwhile doesn’t come around until the 25th of September. On Friday the 25th, early morning, we finally see a clean window. The wind turns cross-offshore from the east at 9 mph, the wave heights are small at 1 ft, but the swell period is a decent 11 seconds, giving it some push for the size. The combined energy is still weak at 40, but for a shortboard or a longboard, it’ll be a fun little session with clean lines. The afternoon holds similar, with clean conditions and a 10-second period.
That’s really the only standout in the whole run. It's a very small wave, so not one for charging, but if you’re just keen to get wet and catch a few clean ones, that’s your window. The rest of the run, right through to the 27th, is either blown out, too small, or both.
If you’re a beginner, the swell size on the best day won’t be an issue, it’s tiny. The rest of the time there is some bigger energy, but it’s messy. Honestly, a few of those days with solid onshore wind and choppy conditions look more like a kite surfer’s playground than a paddle surfer’s.
It’s a disappointing outlook, but these calmer patches do happen. Stay tuned, the forecasts can shift.
Rusty.

Information about the Three Peaks Surf forecast
The above surf forecast table for Three Peaks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Three Peaks can be found by selecting the local surf guide option on the grey menu. Our Three Peaks surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Three Peaks) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Three Peaks may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Three Peaks is 25 km (16 miles) from Swansea. If you plan a holiday in Wales - Gower, look for hotels and other accommodation in Swansea. Swansea has rooms for a wide range of budgets as well as car hire and transport links.
