The Lowdown
Alright, let’s get real here. The Boiler is a reef set-up that’s inconsistent at the best of times, and looking at this 16-day window, it’s pretty much a flat spell. We’ve got a long stretch of nothing before things even start to think about waking up.
From the 13th of July right through to the 24th, the swell is tiny – we’re talking 0.3ft to 1.0ft max. The energy is weak, mostly single-digit to low double-digit readings (8 to 29), so there’s no push at all. The wind is a bit of a mixed bag, but with no real swell, it doesn’t matter. The Boiler is just not breaking.
The water temperature is 69°, which is 9° warmer than normal for this time of year. That’s a massive anomaly. It’s weirdly warm, like bathwater.
The first hint of something happening arrives on the 25th of July – Saturday morning. The swell bumps up to 1ft, but the wind is honking from the WSW at 35 km/h (a fresh breeze) with moderate rain. The energy is still low at 25. Not worth paddling out.
The only real window of interest appears on the 25th of July, Saturday afternoon. The swell jumps to 2ft from the W with an 11-second period, giving a moderate wave energy of 116. Wind is cross from the WSW at 20 km/h. It’s not clean, but it’s the best looking patch in the whole run.
Then the 26th of July, Sunday, shows a little more – 3ft from the WSW (10-second period, energy 150) in the morning, and 3ft in the afternoon. Wind is cross-on, so expect some chop. The 27th and 28th keep similar size (2ft to 3ft) but the period drops to 6-8 seconds, making it weaker and choppier.
Honestly, for almost two weeks there’s no surf. The last few days (from the 25th) offer something small – around 2ft to 3ft – but it’s not clean. The best pick is the afternoon of the 25th of July. That’s it. If you’re a beginner, 2ft is fine; if you’re an expert, you’ll be bored. The reef itself is inconsistent, so this is a rare break showing any pulse. Crowds are possible – it’s a sometimes spot.
No standout, no epic. Just a small, late window with average conditions.

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.
