Rusty here. Let's chew the fat on The Boiler.
To be straight with you, this 16-day forecast is a rough one. There's a massive gap at the start with absolutely no surf to speak of. From Friday July 10th, we're looking at over a week of tiny, weak, and pretty hopeless waves. Don't even bother waxing up.
The only glimmer of hope pops up on Wednesday morning, July 22nd. The water is running a whopping 5° warmer than usual, so you won't need a thick suit. The swell gets to a measly 3ft from the WSW, with a moderate combined energy of 73. The big selling point here is the glassy wind. For the first time in a while, the ocean is dead flat and clean. It's not going to get your heart racing, but for a log on a quiet day with only "sometimes" crowds, it's the one window we've got.
Things finally have a bit more oomph on Saturday, July 25th. The swell pushes up to 5ft from the WSW with an 8-second period, and the combined energy cranks up to a solid 253. That’s the biggest push of the entire run. A cross-off wind from the WNW will keep the faces clean. It’s the best on offer by a long shot, but it’s still not a standout for The Boiler. The direction is a little off from its ideal SW, and the quality is still being called poor.
Honestly, it's a pretty blank run for a spot that's already known for being inconsistent. Don't lose hope though; forecasts can turn around quick.
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.
