The Lowdown
G’day, Rusty here.
Well, I’ve gotta be straight with you—this is a tough one. The whole 16-day window for The Boiler is looking pretty grim. There’s no real swell to speak of, and the conditions are messy. The water is sitting at 67°F, which is much warmer than normal for this time of year, but that’s about the only interesting thing going on.
Monday morning, the 3rd of August, has a tiny 2ft swell from the WSW, but it’s short-period at 8 seconds and blown out by a cross-onshore wind, so it’s not worth paddling out for. The combined energy is weak (62), and it’s just choppy. The same goes for the afternoon—still small and messy.
Wednesday the 5th of August sees a little more size, with 4ft to 4ft from the SW and WSW, but the period is short (6 to 7 seconds) and the cross-onshore wind is moderate, making it choppy and poor. The energy picks up to 148 in the afternoon, but it’s still not surfable. By Thursday the 6th, the morning cleans up a bit with a cross-offshore wind and 4ft from the WSW, but it’s still weak and short-period. The combined energy is 139, but the surf quality is still poor.
From there, it just fades away. The rest of the week and into the second week has almost nothing—tiny waves under 2ft, and often glassy or clean, but you’d be bobbing around on a lake. The best you could hope for is a glassy session on Sunday morning the 9th of August, but with only 0.7ft of swell, it’s not surfable. The same goes for the 10th, 11th, and beyond—flat spells that last for days.
Honestly, the whole 16-day window is a write-off for The Boiler. It’s an inconsistent reef break that rarely fires, and this stretch is a perfect example of that. If you’re desperate, maybe look at the kites—there’s more wind than waves, so it might be interesting for kite surfing, but for paddle surfing, it’s a hard pass. Forecasts can change, but right now, it’s a blank run.
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.
