The Lowdown
Alright, let’s get into it.
Honestly, the next couple of weeks are looking pretty grim for a proper surf. We’ve got a lot of wind and swell that just isn’t lining up for anything decent at Three Peaks. There’s a real block of nothing on the cards for a while.
The first day with anything worth paddling out for doesn’t come until Sunday the 28th. Before that, it’s a whole run of poor conditions. The swell’s all over the place, wind is mostly onshore or cross-onshore, and the energy is just weak.
Sunday the 28th is the one small window that stands out. We finally get a break in the wind, with a light offshore cross-off breeze from the ENE. It’s not big – around 3ft – but it’s clean. The swell is out of the W with a 9-second period, which is okay but nothing special. The energy is still on the low side, but at least the surface is going to be glassy. This is your best bet, but it’s a small, clean wave. Not a big day, but one you can actually enjoy without getting blown off your board.
Before that, there’s a period around the 19th and 23rd where the swell gets a bit more size, pushing 7ft to 8ft, and the energy jumps up. But it’s all messy. Strong cross-onshore winds, lumpy, choppy conditions, and short, weak periods. It’s going to be a washing machine out there. At that size and with that wind, it’s not a pleasant paddle, and it’s definitely not for beginners.
From the 20th, we see a big spike in energy on the Sunday afternoon with that 11ft+ swell and a huge energy reading, but with a 40 km/h onshore wind, it’s just going to be a chaotic, blown-out mess. Not a surfer’s friend.
The days after that are all poor surf conditions until that Sunday the 28th. There’s a lot of wind and the swell drops right off.
So, realistically, if you’ve got a board, you’re waiting until the 28th for a clean if small wave. Everything before that is a skunk.

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.
