The Lowdown

Alright, surfers, let’s have a look at what’s happening over the next couple of weeks at The Boiler. I won’t sugar-coat it – it’s a tough stretch ahead. This is a reef setup that’s inconsistent at the best of times, and the charts are showing a long, dry run.

We kick off Wednesday, the 5th of August, with a messy 5ft swell out of the WSW, but the wind is howling cross-shore at 22 mph, making a lumpy mess of things. The water is sitting at 69°, which is a full 8° warmer than usual – very unusual for this time of year, but it won't help the poor conditions. There's basically no surf worth paddling for all of Wednesday and through the rest of the week. We’ve got tiny, weak pulses of energy barely registering (combined energy values like 12, 7, 8), with most mornings glassy but flat as a pancake. The afternoons get chopped up by the wind again. This pattern drags on right through the first week, all the way to Wednesday, the 12th of August.

Finally, we see a real weak flicker of life on the morning of Thursday, the 13th of August. There’s a slight bump in swell to 3ft from the WSW, with a period of 9 seconds, and clean conditions thanks to a light cross-offshore breeze. The combined energy hits a moderate 111. It’s surfable, but it’s very ordinary. This is realistically the closest we get to a highlight, but don't expect much more than small, weak waves.

The following Monday, the 17th, we see a jump in swell size, with the afternoon pushing 4ft from the WSW and combined energy jumping to a strong 296. However, the 7-second period is short and weak, and the wind shifts to a moderate cross-onshore that's going to make it choppy and poor. By Tuesday, the 18th, the swell is still around 3ft to 4ft, with strong energy readings (150), but the wind is whipping at 22 mph. The morning might be clean, but that kind of wind tends to turn a reef into an onshore washing machine. The setup actually looks more interesting for kite surfing than paddle surfing on those windy days.

The final days are a wash-out again with onshore wind and rain. For a spot that’s already inconsistent, this is a pretty blank run. It won’t stay this way forever, so keep an eye on the forecasts.

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.
