Alright folks, Rusty here. Let's have a look at the Boiler for the next couple of weeks.
Honestly, it's a pretty rough run for this spot. The Boiler is an inconsistent reef break, and the next week and a bit is looking flat and gloomy for any proper surf. The first real sign of life doesn't show up until Wednesday, July 22nd.
We’ve got a long stretch of nothing from Friday, July 10th, all the way through to Tuesday, July 21st. It’s not a single day in there worth mentioning – just tiny dribbles of swell with weak energy, often in the single digits. For example, on that Friday afternoon, we’re looking at a tiny 2 ft swell from the west, with energy so low you’d be floating more than surfing. The water’s sitting at 68°F, which is a whopping 9°F warmer than normal for this time of year – very unusual, and it adds to the overall sleepy, summer feeling.
The only faint glimmer of hope comes on the morning of Wednesday, July 22nd. We get a pulse of 5 ft swell from the west, with moderate wave energy. The wind is offshore from the north at 9 mph, cleaning it up real nice. It’s glassy and the offshore flow should hold for the morning. The swell period is short at 7 seconds, so it’s windswell and a bit weak, but at least it's surfable after all that flatness. The crowd factor says “sometimes,” so you might have company, but for a break that’s rarely breaking, this is the one window to jump on.
By Thursday, July 23rd, the swell dips a bit to 4 ft and gets glassy, but the energy drops back to moderate.
Then it all goes pear-shaped. By Friday morning, July 24th, a massive 12 ft swell arrives from the west-southwest with a long 10-second period and insane energy. The wind is cross-onshore and lumpy. I’d call that a kite-surf day. The afternoon pushes to a monstrous 13 ft, which is huge and messy. Saturday, July 25th is still a solid 7 ft to 7 ft, but the conditions stay cross-onshore and choppy. Total cleanup.
So here’s the bottom line: the whole 16-day window is a bust except for one gem. If you’re flexible, get to the Boiler on the morning of Wednesday, July 22nd. It's the only true standout, and it's not even big – just your best chance at a clean wave in this part of the coast.
Stay salty,
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.
