The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for The Boiler. I’ll be straight with you – it’s a lean run for a while. The Boiler is an inconsistent reef setup, so when it’s off, it’s off. We’ve got a long stretch of nothing really surfable, so you might want to keep the boards in the car for other things.
The first real chance to even think about paddling out doesn’t show up until Wednesday, the 2nd of September. The morning is the pick. We’ve got a clean 7 ft swell from the WSW, with a light cross-off breeze from the NW. The wave energy is strong (522), and the wind should keep things tidy. It’s a solid intermediate wave, but with that size, it’s likely too much for beginners. The afternoon looks a bit more marginal, with a drop to 6 ft, but still clean.
The water temperature is sitting at 69°F, which is much warmer than normal for this time of year – a solid 8°F warmer than average. That’s unusual, so you can leave the thicker wetsuit at home.
After that, the 3rd of September (Thursday) offers a quieter option. Morning has a 4 ft WSW swell with glassy conditions. The energy is moderate (140), and it’s surfable, but it’s pretty ordinary. The afternoon is similar, with 3 ft and glassy winds. Not a standout, but a session if you’re desperate.
The next week looks patchy. There’s a window on Saturday the 5th of September morning with a clean 5 ft swell and glassy conditions, but the energy is moderate (233). Through the rest of the second week, the swell sticks around but the wind is messy. There’s a big, very long-period swell (17 seconds) on the 8th of September, pushing 6 ft to 6 ft, and strong energy (over 2000), but the wind is onshore and lumpy. That’s a no-go for clean surfing – that kind of long-period groundswell is best at a point or reef, but not with that wind.
All in all, Wednesday the 2nd of September morning is the only true standout. Get in while it’s clean.
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.
