The Lowdown
G'day, I'm Rusty. Let's be straight with you – the outlook for The Boiler over the next 16 days is a pretty grim one. We're looking at a long stretch of poor conditions, with no real standouts worth paddling out for. The first decent window doesn't even show up until Thursday the 6th of August, and even then, it's only barely surfable. There's a massive gap of nothing but poor surf right from the start.
The Boiler (a reef setup) is inconsistent at the best of times, and this forecast is a classic example of that. The water temp is about average for the time of year, so no surprises there.
Right from Saturday the 1st of August, we're in trouble. A tiny 1 ft swell from the WSW with a period of 10 seconds is on offer, but the wave energy is pitiful at just 31. The wind is a cross-off, but the waves are just too weak to do anything with. It's a clear "poor surf conditions" call.
Sunday the 2nd is even worse. The swell drops to a weak 1 ft with an 8-second period, and the energy is a measly 13. Sunday afternoon goes glassy, but with no swell to speak of, it's just a flat, pretty lake.
Monday the 3rd sees a tiny bump to 3 ft from the WSW, with a 9-second period and energy of 86. Still, the wind is a cross-on, making it choppy and messy. Not worth it.
Tuesday the 4th and Wednesday the 5th are a write-off. Onshore winds and building chop, with the swell only reaching 4 ft by Wednesday arvo, but the period is a short 7 seconds and the energy is moderate at 135. The wind is howling at 16 mph, making it a complete mess.
Then we hit Thursday the 6th of August. This is the only day that's even close to worth a look. The morning brings a clean 4 ft swell from the WSW with a 7-second period, and the energy is moderate at 102. The wind is a light cross-off from the NW, making it clean. The report says "surfable waves but very ordinary conditions." It's not great, but it's the best we've got. The afternoon goes back to poor.
After that, it's back to tiny, weak swells for the rest of the period. Friday the 7th has a 0.7 ft swell with offshore wind, but the energy is a pathetic 6. The weekend of the 8th and 9th is glassy but flat. The following week sees a few pulses of moderate energy, like on Tuesday the 11th of August arvo with a 4 ft swell and 220 energy, but the wind is a messy cross-shore, so it's still poor.
The last few days are a complete loss. Strong winds, onshore, and tiny swells. The Boiler is not for the faint-hearted in conditions like this, and honestly, this setup looks more interesting for kite surfing than paddle surfing on many of these days, given the strong cross-shore winds and poor wave quality.
Keep an eye on the charts, but for now, I'd save the petrol. This is a classic blank run for the area.
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.
