The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the Three Peaks region over the next couple of weeks. Gotta be straight with you – it’s a slow start. The first week and a bit is mostly a write-off, with weak, messy swells and onshore junk. You’ll be staring at a flat, choppy ocean for most of it. Things don’t really start to look promising until we get towards the end of the month, and even then, it’s a waiting game.
The real standout window opens up on Sunday the 30th of September. That morning we see a jump in size to 8 ft from the WSW, with a moderate 8-second period. The combined energy is solid at 737, but it’s a bit raw and the wind is offshore. The real gem is the afternoon of the 30th. Swell holds at 7 ft, still from the WSW, and the period stretches to 9 seconds. The wind goes light and cross-offshore, dropping to just 10 km/h from the ESE, and the conditions clean right up. That’s the session to circle – expect very good, clean surf with the combined energy pumping at 618.
Now, on that Sunday the 30th, 7 ft is a proper size. At Three Peaks, a swell over 5 ft is already pushing the limits for beginners, and at 7 ft, you’re looking at a wave that’s really for the intermediate and above crowd – experts will have a ball. The water temp is running about average for the time of year, no big anomalies to report.
Wind on the 30th afternoon is light and offshore, so it’ll be clean. That’s a major positive. The swell comes from the WSW, which is bang on the optimum direction for Three Peaks, so expect the break to set up nicely. Crowds can be a factor here sometimes, so if you can get out early or catch it mid-week, you’ll have more room.
After that, the 1st of October keeps things going with a 4 ft SW swell in the morning, light offshore wind from the ESE, and good conditions, though it’s a step down in size. Still a solid runner-up to the main event.
For the rest of the first week and a half, it’s just not on. Those poor surf conditions and zero scores tell the story. By the time we hit Sunday the 27th, there’s a brief tease of a 3 ft clean morning with a long 11-second period WSW swell, and energy at 228, but it’s small. It’s rideable for a log or a longboard, but nothing to get too worked up about.
All up, if you’ve got patience, the 30th of September afternoon is your best bet. Clean, solid swell, good direction, and a setup that’s worth the wait.
Stay salty,
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.
