The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the coming weeks.
First up, the bad news: there’s nothing worth paddling out for until we get to Sunday, August 9th. That’s a solid stretch of flat or junk surf, so don’t bother checking the cams until then. The Boiler is a reef setup that’s inconsistent at the best of times, and this window is mostly a write-off. Water temps are sitting at 69°F, which is much warmer than normal for this time of year – feels like we’re in the tropics.
Right, the one and only standout in the whole 16-day window is Sunday, August 9th, in the morning at The Boiler. Swell comes in at 4ft from the west, with a period of 7 seconds. That’s a fairly short-period wind swell, so it’ll punch a bit but won’t have that long, drawn-out wall. The wind is WNW at 16 mph, blowing cross-offshore, keeping the surf clean. Wave energy is moderate but on the higher side at 298. It’s still a small, short-period wave, so it’s not for beginners, but for an intermediate on a reef, it’s the only real chance you’ll get. The afternoon sees the same size, but the energy drops to 150 and conditions stay clean – just a weaker version of the morning.
Crowds are possible here, and given how rare a decent day is, there’ll likely be some others out. The swell direction is W, which lines up with the optimum SW direction reasonably enough for this spot.
Beyond that, it’s flat, junk, or onshore all the way. The rest of the window is full of poor surf conditions and scores of zero. Honestly, this is one of those quiet runs where the area just isn’t doing its job. The reef looks more interesting for a snorkel than a surf most days.
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.
