The Lowdown
Alright, folks, Rusty here. Let’s be real about this one. It’s going to be a long, quiet stretch. The Boiler is an inconsistent reef setup, and over the next 16 days, there’s barely a pulse. The water’s sitting at about average for the time of year, which is small comfort when there’s nothing to ride.
We’re looking at a big gap of nothing. From Friday the 24th of July right through to Sunday the 2nd of August, the surf is basically flat or tiny. Swell heights mostly below 3 feet, with a weak, short-period windswell from the west that just doesn’t have any push. The wind is messy too – mostly cross or cross-on, with moderate breezes. The energy is pathetic, often under 100 (like 1 to 28) for days on end. There’s a little bump on Sunday the 26th of July, with chest-high 4 to 5ft waves from the west, but the period is a short 6 to 7 seconds and the wind is a fresh 18 mph cross-off. It’s a clean-looking surface, but the wave quality is poor. It’s just not going to be any fun.
The only real chance in the whole outlook comes on Monday the 3rd of August. The morning session shows some promise. Swell is a solid 5ft out of the southwest, with a period of 9 seconds and a combined energy of 393 (moderate). That’s enough to get the Boiler’s reef working. The wind is a light 6 mph cross-off from the WNW, which will keep the surface clean. The guidance says the optimum swell direction is southwest, and that’s exactly what’s showing. It’s the one standout – a window of clean, manageable surf for intermediate surfers. Keep in mind this is a reef break, so pay attention to the tide. Crowds are only sometimes an issue here, so you might get a few waves to yourself. After that, the energy drops again.
Then, on Thursday the 6th of August, the morning brings another decent window. We’ve got 4ft swell from the southwest, period of 8 seconds, and a combined energy of 405 (moderate). The wind is a light 9 mph cross-off from the northwest, keeping things clean. Again, the swell direction is right on the money. It’s a repeat of the same kind of setup – a few hours of decent, surfable waves before the afternoon wind picks up and messes it up.
So, bottom line: the first week and a half is a write-off. The only two windows worth paddling out for are the mornings of Monday the 3rd and Thursday the 6th of August. Keep your expectations low, but those mornings could be a little treat.
Rusty.

Information about the The Boiler Surf forecast
The above surf forecast table for The Boiler provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Boiler can be found by selecting the local surf guide option on the grey menu. Our The Boiler 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 (The Boiler) 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 The Boiler 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.
The Boiler is 9 km (6 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.
