The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for The Boiler over the next couple of weeks. I gotta be straight with you – it’s a grim stretch ahead. We’re looking at a solid block of nothing much, so don’t be in a rush to wax up.

The Boiler is a reef setup, and it’s an inconsistent sort of spot. That’s the story here. We’ve got a long dry spell. From Monday, August 3rd, right through until the very end of the 16-day window, the surf is flat to tiny. The biggest pulse we see is a few days in, on Wednesday, August 5th, with a 6ft swell from the WSW, but the wind is a fresh cross-shore, making it lumpy and ugly. The combined energy hits 452 (moderate) that morning, but the conditions are too poor to bother with. The whole period is plagued by onshore or cross-shore winds, keeping a chop on the surface.

There’s a little window on Thursday morning, August 6th, where the wind swings cross-offshore and the water cleans up, but the swell is dropping fast to 5ft from the west, and the energy is weak at 176. It’s a tease more than anything.

For the rest of the run, swell heights barely reach 2ft, and most days are below 1ft. The energy values are tiny – often single digits – so there’s just no power in the water. The water temp is about average for the time of year, nothin’ to write home about.

Honestly, there’s not a single standout session here. If you’re desperate, that Thursday morning might be the cleanest, but you’ll be fighting for scraps. The second week is especially dead, with nothing but flat, clean conditions on some days, but zero swell. This is one of those stretches where the forecast needs to change big time before it’s worth paddling out.

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.
