The Lowdown
Alright, Rusty here. Let’s get into this one for The Boiler. I’ll be honest, it’s a grim outlook. The next 16 days are mostly flat and choppy, with just one or two moments that might put a tiny smile on your face.
Water temp is 69°F right now, which is a whopping 8°F warmer than normal for this time of year. That’s very unusual, so you’ll be comfortable in boardshorts or a spring suit.
We’ve got a big dry spell right off the bat. From Thursday, August 6th, all the way through to the morning of Wednesday, August 19th, it’s pretty much a write-off. Tiny waves, mostly under 3 feet, with short periods and weak energy. The wind is usually cross or cross-on, keeping everything messy. The best you’ll see in that stretch is a glassy morning on Sunday, August 9th, but with a swell of only 1 foot and a combined energy of just 11, it’s barely a ripple. Not worth getting wet for.
The first real sign of life is on the afternoon of Wednesday, August 12th. Swell comes up to 3 feet from the WSW, with a 9-second period and a combined energy of 156 (moderate). The wind is cross at 25 km/h from the W, so it’s a bit lumpy, but there’s some push. Thursday the 13th is similar, with 3-foot swell and 166 energy in the afternoon, but still that cross wind. It’s surfable, but not clean.
Now, the best of the whole run is the morning of Thursday, August 20th. We’ve got a 2-foot WSW swell, with a 9-second period and a combined energy of 73. The key is the wind: NW at 10 km/h, giving us clean, cross-off conditions. It’s the only session in the entire forecast that’s rated as “surfable” with a score of 1 out of 10. That’s your best bet, but keep it in perspective – it’s still small.
After that, nothing else really fires. The rest of the 20th and the 21st of August see clean conditions again, but the swell drops back to 2 feet to 2 feet, with energy in the 60s. It’s just not enough.
So, bottom line: The Boiler is a reef break that’s inconsistent at the best of times, and this 16-day window is a long, flat stretch. The only morning that’s even worth a look is Thursday, August 20th, when the conditions finally line up for a clean, small session. Don’t get your hopes up, but if you’re local and jonesing, that’s your window.
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.
