The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this isn’t a classic 16-day stretch for The Boiler. We’ve got a long, quiet run with hardly anything to get excited about. The first real flicker of something surfable doesn’t show up until the morning of Saturday the 15th of August, so that’s over a week of flat to tiny, poor-condition slop. The combined swell energy is mostly under 100 (weak) right through until that point, and the wave heights barely tickle 2 ft. It’s a tough run.
The only bright spot in the whole window is the morning of Saturday the 15th of August. At The Boiler – a reef break that’s inconsistent and can get a few people around – we’ve got a 2 ft swell from the WSW with a period of 8 seconds. The wind is a light WNW breeze at 6 mph, coming cross-offshore, which keeps the surface clean. The combined energy hits 99 (moderate), and the comment says the waves are “surfable” but conditions are very ordinary. It’s not a standout by any stretch, but it’s the only time the score isn’t a zero. For the rest of the period, the wind is too strong, the swell is too small, or it’s cross-on and choppy. The water temperature is about average for the time of year.
If you’re desperate, Saturday morning the 15th is your only chance for a paddle. Otherwise, this is a write-off. The Boiler needs a proper SW groundswell with light offshore winds to really fire, and we just aren’t getting that in this forecast. It’s a long blank stretch, and that’s just how it goes here sometimes.
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.
