The Lowdown
Alright folks, it's Rusty here. Let's be straight with you about this 16-day stretch. I've had a good look at the charts for The Boiler, and to be honest, it's a pretty grim outlook. We're looking at a run of poor surf conditions that starts now and doesn't let up for the entire forecast window. The Boiler is an inconsistent reef break, and this is one of those spells where it just isn't firing. From August 1st right through to the 16th, every single report is underwhelming. There are no standout sessions, no hidden gems to chase.
We kick off August 1st with tiny, weak 1ft swell from the WSW and a moderate cross-breeze. The water is a notable 68°, which is much warmer than normal for this time of year. The energy is basically non-existent (27). August 2nd offers a brief moment of glassy conditions on Sunday afternoon, but with the same limp 1ft swell, you're just looking at flat, clean water. Not worth the drive.
Moving into the work week, the swell starts to creep up. By August 5th, we're seeing 5ft of WSW swell, but it's all short-period windswell at 7 seconds, creating a lumpy, cross-shore mess. The combined energy (229) is moderate, but the quality is junk. The wind stays messy.
August 6th Thursday morning actually shows clean conditions with a cross-offshore wind and 5ft swell from the W, but it's still poor quality and that short period kills any real power. It's a tease, not a session.
There's a slight bump in energy on the weekend of the 12th and 13th, with some moderate 3-4ft swell and moderate wave energy (185 and 138), but every single session is plagued by poor conditions. The wind is never right, and the swell direction never matches the optimum SW direction for The Boiler to work its magic on this reef.
The final weekend, August 16th, sees the biggest swell of the period at 6ft from the W, with strong energy (348). But again, it's a short-period, choppy, cross-onshore mess. At that size, with those conditions, it's a washing machine, not a wave. For a break that's inconsistent by nature, this 16-day forecast is a total bust. The only upside is that it rarely stays this poor for long, but for now, save your board wax.
Stay patient.

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.
