The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s comin’ down the pipe for this stretch of coast. I’ll be straight with ya – it’s a lean run, and there’s a big ol’ gap at the start with nothing to paddle for. We’re talkin’ from Wednesday the 22nd of July all the way through to the end of the month with no real recommendations. The surf that shows up is tiny, weak, and the conditions just aren’t lined up.
The first faint pulse of something rideable doesn’t arrive until the afternoon of Thursday the 31st of July. Even then, it’s pretty average. The Boiler sees a little bump in energy with a combined swell energy of 156, which is moderate, but the swell’s only 5 ft from the WSW with a short period of 6 seconds. That’s a crumbly, weak wave, and the wind is a cross-shore from the WSW at 9 mph, which won’t help it clean up much. Crowds are possible here, but honestly, with surf this average, I’d expect it to be quiet.
The real standout, and the only one worth highlighting, hits on Saturday the 1st of August. The swell builds to 6 ft from the WSW, with a period of 9 seconds – that’s a solid groundswell with some good energy in the water. The combined energy jumps to 862, which is strong, and that’s a legit step up. The morning has a cross-on wind from the SSW at 12 mph, which is a bit rough, but the afternoon sees the wind pick up to 22 mph from the SW, making it fresh cross-onshore and lumpy. That’s messy. Still, for an inconsistent reef break like The Boiler, this is the best chance at a wave all forecast. The swell direction is bang on from the optimum of SW, which is a bonus. It’s a bit too big for beginners, but for an intermediate, Saturday morning before the wind gets too rowdy is your window.
Then Sunday the 2nd of August holds onto that energy with 6 ft from the W in the morning, period 8 seconds, and a cross-shore wind from the W at 9 mph. Combined energy of 407 is still strong. It’s a touch bumpy but rideable. By afternoon, the wind picks up to 16 mph, and it gets chopped.
After that, the swell drops off fast. Monday the 3rd of August morning is glassy, but only 2 ft from the WSW. Nice and clean, but tiny. The rest of the run into the 6th of August is small stuff under 2 ft, with periods of glassy conditions but no power to speak of.
So, the call is simple: if you’re desperate, aim for the morning of Saturday the 1st of August at The Boiler. It’s not perfect, but it’s the only real swell of the whole outlook. The rest is a waiting game.
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.
