The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this forecast for Three Peaks is a tough one to swallow. We’ve got a 16-day window ahead, and the honest truth is there’s barely a session worth paddling out for. The swell is tiny, the energy is weak, and most days are a write-off. We’re looking at a long gap of poor conditions right from the start, with only a couple of moments in the second week that might give you a mediocre wave.
Let’s get into it. The water’s sitting at 69°F which is a solid 7°F warmer than average for this time of year – that’s very unusual, like swimming in a bath. But that’s where the good news ends.
From Saturday the 15th of August right through the whole first week, it’s a dead zone. The wave heights are stuck between 1.0ft and 4ft, barely cracking 3ft most days. The combined swell energy is a pitiful 35 to 150 (weak to moderate at best), and the period is short, mostly 5 to 8 seconds – that’s windswell junk, not real groundswell. The wind is all over the place: cross-off, cross-on, cross – it’s rarely clean, and when it is, the swell is too small to do anything with. Monday the 17th has a 2ft W swell with a 5-second period and cross-off wind in the morning, but it’s just a dribble. Tuesday the 18th morning sees a 4ft W swell, the biggest of the week, with a 6-second period and moderate energy (150), but the wind is cross-shore with a chop – messy, onshore, and not worth the drive. The rest of the week is more of the same: tiny, choppy, and poor. There’s a clean spell on Friday the 21st morning with 3ft WSW swell and cross-off wind, but the energy is only 83 and the period is 6 seconds – it’s a marginal mushburger.
Now, into the second week, things get even smaller. From Saturday the 22nd of August through to Wednesday the 26th, the swell drops to 0.3ft to 1ft, with energy between 11 and 34 (very weak). The period does stretch out to 13-14 seconds on Monday the 24th and Tuesday the 25th, but that’s a 0.3ft long-period groundswell – it’s a ghost, barely a ripple. The wind is clean (offshore or glassy) on several mornings, but there’s simply no water moving. For a break like Three Peaks, which is an exposed beach break, this long-period stuff will just break too straight and close out – not that you’d even get a ride.
The only glimmer comes on Thursday the 27th of August morning. We’ve got a 2ft WSW swell, 8-second period, clean cross-off wind from the ESE at 10 km/h, and an energy of 45 (weak). The guidance says the conditions are “surfable but very ordinary” – that’s the best we’ve got. Then Friday the 28th morning is glassy, with 2ft WSW swell, 9-second period, and energy of 49 – again, just surfable. But these are tiny waves, and the wind turns onshore in the afternoons. For a beginner-friendly spot that’s fairly consistent, it’s a real bummer. The crowds are possible here, but with conditions this poor, you’ll probably have the place to yourself.
That’s your lot. Nothing to get excited about. Keep your eyes on the forecasts – things can change.
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.
