The Lowdown

Alright, grab a seat. Rusty here. Let's talk about what's on offer.

Honestly, looking at this forecast, it's a bleak one. We're staring down the barrel of a long, frustrating stretch with nothing really worth paddling out for. The swell just isn't there to build any enthusiasm.

Right off the bat, it’s a bit of a desert. There's an immediate gap starting now where there's just no worthwhile surf to recommend. We're looking at a long run here with the biggest size being a tiny 2ft back on the 30th of July, but that came with a cross-offshore wind at 15 km/h and the combined energy was a pretty weak 27, which just doesn't cut it for a proper session. It lasted about a week of this nothingness.

The water at The Boiler is running at a pretty remarkable 69°, a full 9° warmer than it should be for this time of year. That's genuinely unusual.

Moving through the first week of August, it just doesn't improve. The morning of the 2nd of August shows a glassy surface but with a mere 1ft of swell and combined energy of just 13. It's a flat spell. Even the cleaner days, like the morning of the 3rd of August with 2ft of swell from the WSW and combined energy of 70, were a total non-event thanks to a cross-onshore breeze. That's actually the best-looking set of conditions over the first 9 days, but it's still not enough to get excited about.

Look, if you look towards the second week, around the 12th of August (Wednesday), things get a little less terrible. We've got some offshore wind forecast at 20 km/h with 3ft from the W and combined energy of 41 on the afternoon of the 12th. It's clean again on the morning of the 13th with 1ft from the W, combined energy of just 17. It's a promising sign after such a flat run, but given how low the wave heights are, it's still hard to call it a standout. It's really a case of "you'd be desperate for a paddle."

Because the swell is so weak and the wind is often messy in this direction, this setup at The Boiler looks far more interesting for a kite surfer than someone on a paddle board through the majority of this window. The afternoons especially are a mess with strong cross-shore winds.

Simply put, there are no real standouts here. It’s a flat spell. There's no way around it. Forecasts can change, but for now, keep the board in the bag.

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.
