The Lowdown
Yo, Rusty here. Let’s get straight into it. To be honest, the outlook for this stretch is a bit of a bummer. We’re looking at a 16-day run with no real standout surf to speak of. The Boiler, our only spot on the radar, is a tricky little reef break that’s inconsistent and pretty exposed to a SW swell window, but the swell just isn’t cooperating.
The whole period kicks off on Thursday, July 23rd, with a tiny 0.7 ft W swell rolling in, and while the morning is glassy (0 mph wind from the west), the energy is a weak 10. That’s just not enough to get you out of bed. The next few days are a washout. Friday the 24th and Saturday the 25th offer up meager swell, mostly 0.3 ft to 3 ft, with short, choppy periods (5-8 seconds) and cross-shore winds that just mess up the surface. The combined energy stays below 34 – pathetic.
We do see a bit of a pulse on Sunday the 26th. The swell bumps up to 4 ft from the W, with a period of 7 seconds, and the energy jumps to 171 (moderate). Winds are cross-offshore from the NW at 12 mph, so the surface stays clean. The Boiler might have a few lumpy, backline waves, but that 7-second period means it’s not going to be a classic, lined-up reef wave. It’s the best of a bad lot, but not something I’d paddle out of bed for.
The first week of August (from the 1st to the 7th) is a real desert. The few days with any height, like Sunday the 2nd with 4 ft WSW swell and 160 energy, get ruined by cross-onshore winds and lumpy chop. The water temp is about average for the time of year, no anomaly to speak of.
There’s a tiny flicker of hope on Wednesday, August 5th, and Thursday, August 6th, with some glassy mornings (0 mph wind) and a 1.0 ft to 1 ft WSW swell, but the energy is still a weak 15 to 24. That’s a lake, not a surf break. The whole 16-day window is a blank run, and that’s a bit more normal for an inconsistent spot like The Boiler, but it doesn’t make it any easier to swallow.
Rusty, signing off.

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.
