Table - best surf conditions forecast for The Boiler over the next 16 days.
Righto, let’s have a look at what’s on the table for The Boiler over the next couple of weeks. I’ll be straight with you, this isn’t shaping up to be a classic run. We’re looking at a real lean stretch with barely a ripple for days on end.
The water’s sitting at 68°F, which is a solid 8°F warmer than normal for this time of year – that’s very unusual, like the ocean’s had a hot bath and isn’t letting go.
The first week is a tough watch. From Saturday the 11th right through to Friday the 24th of July, it’s pretty much all “poor surf conditions” with tiny, weak swell and a whole lot of nothing. The combined wave energy is mostly teeny, two-digit numbers, rarely even cracking 30, so you’re looking at flat spells and scraps. Winds are all over the shop, sometimes clean but with next to no swell to work with.
The first real flicker of hope doesn’t come until Friday the 24th of July in the afternoon. We get a pulse of 6 ft swell from the WSW with a short period of 6 seconds, but the energy jumps to 230 – moderate energy at last. The wind swings offshore from the N at 12 mph, making for clean conditions. It’s surfable but very ordinary, a one-out-of-ten kind of deal. The Boiler is an inconsistent reef break, and crowds are possible.
Then Saturday the 25th of July brings a bigger spike: 8 ft from the W with an 8-second period. The combined energy rockets to 887 – strong wave energy. But here’s the kicker – the wind is cross-onshore from the SW at 9-16 mph, putting a chop on it. That size is only for experienced surfers, and with the messy wind, it’s not the clean day we’d hope for. The next morning, Sunday the 26th, drops right back down to 3 ft with fresh cross-onshore winds, lumpy and poor again.
Honestly, if you’re desperate for a paddle, that Friday afternoon the 24th is the standout, but it’s a weak one. The bigger swell on the 25th has the power but the wind wrecks the quality. For most of the run, the beach setup here looks more interesting for kite surfing than paddle surfing with the strong winds and bumpy conditions.
Keep an eye on the forecast, because a blank run like this tends not to stick around forever.

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.
