The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – the whole 16-day window is a real struggle. There’s a massive gap of nothing but flat, crummy conditions from now all the way through the first week of August. The first sign of anything that even looks like a wave doesn’t show up until Friday the 7th of August, and even then it’s a bit of a mess. That’s a solid 13 days of waiting for a pulse.
The only spot on the radar is The Boiler, a reef setup that’s notoriously inconsistent, and the forecast proves it. For the first week, through the end of July and into early August, you’re looking at ankle-slappers and bumpy, cross-shore junk. The wind is mostly on it or cross, and the swell is barely a whisper. The water is a very unusual 69°F – much warmer than normal for this time of year.
The one true standout, and I mean the only one worth getting an early mark for, is the morning of Saturday the 8th of August. The sun should be out, with a slight air, glassy wind from the west at just 3 mph. That’s dead clean. The swell is coming from the west-southwest at a solid 6 ft, but it’s a short-period wind swell at just 8 seconds. The combined energy is strong (470), so there’s some push behind it, but that short period means it’ll be a bit walled-up and lumpy. It’s not a beginner wave at that size – it’s more for the lads who can handle a bit of a thumping. The crowds are only listed as “sometimes”, so you might get a few waves to yourself.
The afternoon of that same day, the wind picks up to a moderate cross-shore, and it gets choppy, so the morning window is the only real play. That’s the one. It’s a long way off, so keep your fingers crossed, but that Saturday morning window is the best we’ve got.
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.
