Gather 'round, me hearties, Rusty here with a look at what's on offer. It's a bleak stretch ahead, I won't lie to ya. We're looking at a solid run of barely a ripple, so don't be in any rush to grab your board. The whole 16-day window is a tough one.
The only spot we’ve got to talk about is The Boiler. It's a reef break, inconsistent by nature, which is a shame. For the first ten days, from Friday the 3rd of July right through to Sunday the 12th, it's a total write-off. We're talking tiny, weak swells and messy wind. The wave energy barely registers, most of the time sitting between 4 and 30 (weak energy). The swell is tiny, around 0.7ft to 3ft, and the period is short, so there's no grunt to it. The wind is mostly cross or cross-on, chopping things up. A couple of mornings on the 7th, 11th, and 12th turn clean, but with only 0.7ft to 1ft of swell, it's a lake, not a surf.
There's a glimmer of something on Monday the 13th. The morning glass-off with a tiny 2ft WSW groundswell at a proper 12-second period will have the surface looking like a mirror. The combined energy jumps to 97 (weak to moderate), meaning there's enough to push a log around. But by the afternoon, the wind shifts and the conditions turn ordinary again. After that, from Tuesday the 14th through Saturday the 18th, it's back to the same story: small, weak, and choppy. The swell direction is coming out of the W to WSW, which lines up with the optimum for The Boiler, but there's simply not enough size or clean wind to make it worthwhile.
Honestly, this is a stretch where you're better off staying home and checking the charts. If that Monday 13th morning glass-off holds true, it's the only window, but don't hold your breath.

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.
