The Lowdown
Alright, Rusty here, let’s look at what’s on offer around the Three Peaks area.
To be straight with you, this is a tough run. Over the next 16 days, we’ve got nothing that scores high enough to call a proper standout session. The water is unusually warm right now, sitting at 67°F which is a massive 6°F above average for this time of year – feels more like a late summer bath than the start of a swell season.
The pattern starts flat and messy. Tuesday the 25th through Thursday the 27th sees barely a ripple, with tiny 0.7ft to 1ft swells, mostly cross-off or cross winds, and a combined energy that’s barely making a whisper (19 to 39). Not worth wetting a wetsuit for.
Things get a little more interesting from Friday the 28th into early September, but the wind is the killer. We get a pulse of waist-to-head-high swell on Friday morning the 28th – 6ft from the southwest with moderate wave energy (214) – but it’s blown out with 16 mph onshore winds. That pattern holds through the weekend: Saturday the 29th has 5ft to 7ft of SW swell, but with fresh to strong onshore breeze. Sunday the 30th doesn’t do us any favours either: 5ft of WSW groundswell, period 10 seconds, energy up to 434, but cross-onshore winds and a choppy surface.
Into the first week of September, the swell drops back then builds again. On Monday the 7th and Tuesday the 8th we see some serious size – 10ft to 12ft from the SW – but that’s big, expert-only territory, and the wind is howling onshore. The wave energy is pumping (1811 to 2300), but for paddle surfing it’s a mess. This setup would be more interesting for kite surfing than a log.
There is one brief window that nearly gets there. On Saturday the 5th of September, we have 3ft of WSW groundswell with a 11-second period, combined energy at 157, and a clean cross-off wind from the NNW at 19 mph. It’s small, but with that long-period groundswell and clean conditions, Three Peaks might offer a few lined-up waves for the experienced crew. Not a standout, but a winnable morning if you keep expectations in check.
For beginners, even the smaller days (like the 4ft on Wednesday the 2nd) have onshore wind, so the chop and closeouts won’t be friendly.
If you’re holding out for a miracle, this isn’t the window. These gaps of days with no real recommendation are par for the course here when the wind doesn't play ball. Forecasts can change, but right now it’s a waiting game.
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.
