The Lowdown
Alright folks, Rusty here. Let’s be straight – the next 16 days at The Boiler are a total write‑off for surf. Not a single decent wave in the window. The forecast shows nothing but tiny, weak swell and poor conditions the whole way through. The Boiler is an inconsistent reef anyway, and it’s not cooperating at all. The water is running much warmer than normal for this time of year – about 69°, which is a solid 9° above the long‑term average. That’s a big anomaly, but it doesn’t help the waves.
The first few days are flat, with swell heights barely 0.3ft to 0.7ft – not even enough for a log. The combined wave energy sits at just 3 (weak) on Sunday the 19th, and stays under 10 until later. Winds are a mixed bag: some glassy mornings on Monday the 20th and Thursday the 23rd, but with zero swell it’s just a flat calm. The best chance of any size comes around Sunday the 26th of July, when a short‑period WSW swell pushes 5ft and combined energy reaches 190 (moderate). But the period is a weak 6 seconds, and the break still gets flagged as poor surf conditions. The wind is cross‑offshore, so it’s clean, but the waves are too short‑period and messy – better suited for a bodyboard than a proper surf. After that, it fades quickly back to nothing.
The rest of the month and into early August offers nothing. Even the offshore winds on Wednesday the 22nd, Tuesday the 28th, and Saturday the 1st of August can’t turn the tiny 0.7–2ft bumps into anything rideable. The combined energy never climbs above 48 during that stretch. There’s a rare glassy morning on Monday the 3rd of August, but again, only 0.7ft of swell. The Boiler is a reef that needs a solid SW groundswell to light up, and we’re not getting a sniff of that. Crowds are sometimes an issue here, but with conditions like this, you’ll have the place to yourself – and still no waves.
It’s a blank run, plain and simple. When the forecast shows nothing but “poor surf conditions” for sixteen straight days, it’s not a temporary blip – it’s just the nature of this spot. Sometimes the ocean just doesn’t deliver. Keep an eye on the charts, but for now, save your petrol.

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.
