The Lowdown
Alright, let’s be straight with you. This is a tough one.
The forecast for the next 16 days is a real flat spell. There are no good surf options on the table at all. Nothing. The swell is basically non-existent for the entire period, with wave heights barely scraping a tiny 0.7ft and combined energy readings that are minuscule, often in single digits. It’s the kind of run that’s all too common for this area when the ocean just shuts down.
The Boiler is a reef break that’s already inconsistent, and it’s not even going to break properly. You’ll see a few tiny pulses of swell from the SW and W, but the energy is so weak you’d be fighting for a knee-high ripple. The only positive note is that there are plenty of glassy or offshore windows, especially on the mornings of the 17th, 20th, and the afternoon of the 15th of July, but with nothing to ride, clean conditions are just a tease. The water temperature is about average for the time of year.
From the 15th of July right through to the 30th, this is a total write-off for paddle surfing. If you’ve got a kite, some of those breezier afternoons with a bit of cross-shore wind might look more interesting, but for a surfboard? You’re better off staying home. It’s a blank run, and it’s pretty normal for the area when the swell windows just don’t line up. Forecasts can change, but right now, there’s nothing to get excited about.

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.
