The Lowdown
G’day, Rusty here. I’ve got to be honest – the next couple of weeks for The Boiler are looking like a real dud. There's a long, flat stretch of messy conditions, so don't get too excited. The water is a very unusual 69°, much warmer than normal for this time of year, but that's about the only interesting thing.
It all starts on Sunday, July 26th, with a cross-off wind from the WNW at 19 mph and a 5 ft swell from the west. The period is a short 7 seconds, and the combined energy is weak (203). The call is poor surf conditions, and that sets the tone for the next week and a half.
From Monday, July 27th through Thursday, August 6th, it’s a real write-off. The swell is tiny, mostly under 3 ft, with short periods and cross or onshore winds. The combined energy stays weak, barely getting into three-digit territory, and the wave comment is consistently "poor surf conditions." It’s a proper 10-day gap with nothing worth paddling out for.
Finally, on Friday, August 7th, we get a slight glimmer. Morning brings some clouds, a light NW wind at 3 mph that’s cross-off, and a waist-high 3 ft swell from the WSW. The period is still short at 6 seconds, but the conditions are clean. The combined energy is weak (82), and it's only rated as "surfable waves but very ordinary conditions." It’s not a standout, just the least bad day of the run.
Sunday, August 9th afternoon is another flicker. A tiny 5 ft swell from the west, but with a short 5-second period and clean, glassy conditions, it might offer a few clean but weak rollers for the patient surfer. The combined energy is moderate (129), and again, it's "surfable but ordinary."
The rest of the period into Monday, August 10th fades back into poor, onshore slop. There’s simply no good surf on offer. The Boiler is inconsistent at the best of times, and this 16-day window is a classic blank run for the area. Forecasts can change, but as it stands, leave the board at home.
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.
