The Lowdown
Alright, Rusty here, let’s break down what’s cooking for Three Peaks.
Honestly, the next couple of weeks are mostly a bust. There’s a whole lot of nothing happening until we get way out to September 23rd. That’s a long stretch of messy onshore wind and weak, short-period swell. The energy numbers are low to moderate for days – combined energy values between 95 and 311 – and the wind is just not your friend. You’ll see “poor surf conditions” over and over, so don’t bother suiting up early.
The one shining moment, the only one worth getting stoked about, is Wednesday morning, September 23rd. That morning we get a solid 10ft swell from the WSW, and the wind goes glassy with a light offshore from the E at just 3 mph. That’s a clean-up set if I’ve ever seen one. The combined energy is massive at 1034 (strong wave energy), so there’s plenty of punch. That size is for experienced surfers only – over 8ft is expert territory. The period is short at 8 seconds, so it won’t be the smoothest groundswell, but with that offshore wind, Three Peaks will have some steep, clean walls. Crowds can show up sometimes, but on a day like this, you won’t care.
The afternoon of the 23rd holds that same 10ft swell, with WSW 3 mph glassy conditions. The energy jumps to 1076 (very strong wave energy). This is your absolute best window. You can’t ask for much more than glassy surf and a solid west swell.
Before that, from the 10th through the 22nd, it’s mostly garbage. The only brief highlight is Friday morning, September 11th, with a 5ft swell and a NNW cross-offshore breeze at 9 mph. The wave comment says “expect good surf conditions,” but the combined energy is only 307. It’s clean and rideable if you’re really itching, but it’s nothing special.
After the 23rd, the swell drops fast. The 24th has cleaner winds but the swell is down to 5ft and then 4ft with a longer 11-second period on Thursday afternoon – that one is a clean groundswell but low energy (275). The 25th is back to ordinary.
Here’s the bottom line: save your energy for Wednesday, September 23rd. That’s the day – massive glassy swell and offshore winds, strictly for the experienced. Mark it.
Water temp is sitting at 66°F, which is a few degrees warmer than usual for this time of year – feels pretty nice.
Rusty, out.

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.
