The Lowdown
G’day, I’m Rusty. Let’s break down the outlook for Three Peaks over the next 16 days.
Look, it’s grim for a long while. The water’s sitting at 68°F with an anomaly of 7°F above normal, so it’s much warmer than usual – that’s very unusual for this time of year. But the surf? There’s nothing worth paddling out for from the start until late August. Swell is tiny, wave energy is weak – readings like 18 to 84 (weak energy) – and the winds are sloppy, mostly cross-onshore. You get a little bump on Tuesday 18 August with 4ft swell from the WSW and moderate energy (138), but the period is a short 6 seconds and the wind is cross or cross-on. Not worth it. Wednesday 19 August shows 5ft swell, but again short period and choppy. This break is fairly consistent, but that doesn’t matter when it’s all poor quality.
Then from around Monday 25 August, it drops to 0.3ft or less, with energy as low as 8 (weak). There’s a glassy moment on Sunday 23 August with gentle offshore wind from the NE, but the swell is only 0.7ft – you’d be lucky to get a ripple.
The one bright spot – and I mean the only one – is way out in the forecast. On Friday 28 August and Saturday 29 August, the models show a 16ft to 12ft WSW groundswell with a period of 10-12 seconds. The combined energy is enormous: 6211 to 6878 (very strong wave energy). The wind is offshore from the ENE and NE, so it’ll be clean. But here’s the deal: over 8ft, it’s only for experts, and 16ft is huge for this spot. Three Peaks is a beginner-friendly break on a normal day, but this is not that day. It’s a promising but less certain long-range call, and only the most experienced should even consider it. Crowds are possible here, but with size like that, most will be watching from the sand.
So, to sum it up: the first week is a bust. The second week has one monster, expert-only swell that’s too big for the majority. If you’re a beginner, give it a miss. If you’re a seasoned charger, keep an eye on 28 August and 29 August, but respect the ocean. Forecasts can change.

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.
