The Lowdown
G’day, I’m Rusty. Let’s get into it.
Honestly, mate, it’s a pretty flat and ordinary run for The Boiler over the next 16 days. There’s no real standout session, and the first few days are a write-off. The swell is tiny and the winds are messy. The water temp is sitting at 68°F, which is a massive 7° warmer than usual for this time of year – proper weird, feels like bathwater.
The first real chance to paddle out comes on Thursday 13 August morning. We’ve got a little 2ft swell from the WSW, period 8 seconds, and the wind is offshore from the north at 9 mph. It’s clean, but the energy is weak (combined energy 70). It’s surfable, but only just. The same goes for Friday 14 August morning – glassy conditions with the wind dropping to nothing, but the swell is still 2ft and short period. A bit of a tease.
On Saturday 15 August morning, there’s a slight bump to 4ft from the WSW, period 7 seconds, and glassy conditions. The combined energy nudges up to 114 (moderate), but the waves are still ordinary. Sunday 16 August morning is similar – 4ft, glassy, but the period is still short at 7 seconds. The energy is 191 (moderate), and the conditions are clean, but the surf quality is just not there.
Overall, the best of a bad bunch is the Sunday 16 August morning session. The swell is 4ft from the WSW, wind is glassy, and it’s the most energy we see all outlook. But don’t kid yourself – it’s still only “surfable” at best. The Boiler is inconsistent and rarely breaks, so this blank run is kind of normal for the area. Hold tight, forecasts can change.
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.
