Table - best surf conditions forecast for The Boiler over the next 16 days.
Alright folks, Rusty here. Let me be straight with you – the next couple of weeks are looking pretty grim for a paddle. We're looking at a long stretch of flatness all the way through to the end of the month, so don't be in a rush to wax up.
The only thing that even remotely flickers on the radar is at The Boiler, a reef setup that is rated as inconsistent. The water temp is about average for the time of year, so nothing unusual there.
From now through Sunday, 27 July, it's a desert. There will be a gap of about two weeks with no surf worth mentioning. The wind is mostly cross or cross-off, but the swell is tiny, barely a ripple, with the combined energy stuck in the single digits and teens (like 14, 9, 27). It's all "poor surf conditions" with scores of 0. You'd be better off checking the kite forecast because the wind is more interesting than the waves.
Then, on the very last day of the outlook, Monday morning, 27 July, we get a blip. A 4ft swell from the WSW, with a period of 8 seconds, and the combined energy jumps to 430 (moderate). The wind is a gentle cross-shore from the W, which should keep it clean. It's only a 1/5 rating, and it's described as "marginal surf forecast or questionable tide conditions," so don't book the day off work. It's a slim hope, but it's all we've got.
Stay patient, crew. The ocean will wake up again.
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.
