The Lowdown
Right, grab a brew, settle in. Old Rusty here, and I’ve been staring at the maps for your patch for the next couple of weeks. I’ll be honest with you, mate – it’s a grim outlook for a paddle surfer. The only spot on the cards is The Boiler, a reef set-up, but the news ain't great for a while.
The Boiler is an inconsistent wave, and it’s going to live up to that name. For the first ten days, from Thursday the 23rd of July right through to the end of the month, we’re looking at a whole lot of nothing. Flat spells, tiny dribbles, and messy wind. The water is a very unusual 69°, which is much warmer than normal for this time of year, but that’s about the only thing to get excited about. There’s a big gap of small, poor surf here. The odd bit of swell tries to push in, like on Sunday the 26th with a short-period 4ft from the west, and the combined energy is moderate (244), but it’s being chopped up by onshore wind. Not a single day in that first stretch is worth the drive.
Then, we finally get a flicker of hope. Look at Sunday the 2nd of August. The morning glass-off is calm, and we’ve got a 7ft west-southwest swell rolling in. The energy is strong (574), and the winds are light and offshore. That’s the standout. The swell is a beast, over 8ft, so this is for the experienced crew only. The period is a short 8 seconds, so it’ll be a bit fat and walled up, but it will be clean. If you’re an expert, this is the one morning to circle. Keep in mind, it’s a reef, and it’s “sometimes” crowded, so expect company if you’re heading out that morning.
The afternoon of that same day, the wind swings cross-shore and the quality drops. After that, it’s back to the doldrums. Monday the 3rd has a solid 8ft swell, but the wind is a messy cross-onshore, making it a choppy mess. The energy is very strong (1024), but the conditions are poor. Honestly, that day looks more interesting for the kite surfers than anyone on a paddle board.
The rest of the first week of August is just small, weak, and messy again. Short period swells, a bit of a cross-off breeze here and there, but nothing that will get the heart pumping. The forecast is a long way out for that second week, so don’t pin your hopes on it just yet.
Bottom line: Get your gear ready for that Sunday morning, the 2nd of August. It’s the only real chance for a proper session. The rest of the run is a solid bust.
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.
