The Lowdown

Righto, let’s have a look at what’s on offer for the next couple of weeks. It’s a bit of a flat spell to kick things off, I gotta be honest. For the first few days through to the weekend, there’s hardly any swell to speak of, and what little there is gets chopped up by onshore or cross-shore winds. You’re looking at a gap of several days where it’s just not worth paddling out unless you’re a masochist.

Things finally start to look a little more promising around Thursday the 20th of August. That morning at Three Peaks, we’ve got a pulse of swell coming in at 4.9 ft from the W, with a period of 7 seconds and the combined swell energy sitting at 246 – that’s moderate energy. The wind is light from the NW, so it’s a cross-shore setup with a slight cross-chop. It’s still fairly average, but it’s the first real chance of a wave in the whole window. This spot is exposed to the W and the optimum swell is also from the W, so it’s pointing right at it. Crowds are listed as *sometimes* busy, so you might have some company. The water temp is about average for the time of year.

That same afternoon, it gets a bit messier with a moderate cross-shore breeze, and the energy jumps up to 490 (moderate) but the quality drops off. Friday morning the 21st of August is the real standout for the entire forecast period. The swell drops right back to 2.0 ft from the WSW, period 8 seconds, but the big news is the wind: NE at 10 km/h, light and *offshore*. That’s clean surf, glassy conditions. The energy is weak at 71, but for a beginner-friendly spot like Three Peaks, those small, clean waves will be perfect. It’s rated 3/5 difficulty and is ‘fairly consistent’.

After that, we go into another dry spell. From Saturday the 22nd of August right through to around Monday the 24th, swell drops to tiny 0.7 ft to 1.0 ft – not worth even looking at. A bit of a pulse returns on Tuesday the 25th with 4.3 ft and longer period at 9 seconds, but the cross-onshore wind ruins it – 267 energy, moderate, but messy.

Then we’ve got a bigger event building for the very end of the outlook. Around Saturday the 29th of August, the swell size starts to climb. By Monday the 31st of August morning, we’re looking at 5.9 ft from the SW with a period of 6 seconds, energy of 229 (moderate), but it’s cross-on and fairly choppy. That afternoon jumps to 7.9 ft from the SSW, 7 seconds, with a very strong wave energy reading of 731 – that’s getting into strong territory. But the wind is onshore, so it won't be clean. That size is getting too big for beginners.

Into the first of September, Tuesday the 1st, we’ve got 7.9 ft from the WSW with a long period of 10 seconds and energy of 1021 – that’s strong to very strong wave energy. That’s a proper groundswell. The wind is directly onshore, so it’s blown out. Wednesday the 2nd of September sees the swell drop a bit to 6.6 ft with a period of 9 seconds and energy of 630 (moderate-strong). The wind shifts NW, making it cross-shore with a slight cross-chop, which is a bit better, but still not perfect.

Honestly, for the whole 16-day window, the Friday morning 21st of August is your best bet by a long shot. The combination of offshore wind, small clean lines, and a spot made for beginners makes it the standout. Every other session is either flat, messy, or blown out. Keep your eyes peeled, but don't expect much.

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.
