The Lowdown
Alright, Rusty here. Let’s see what’s cooking at Boiler Bay.
We’re looking at a long, quiet stretch ahead. If you’re keen for a paddle this week, you’ll want to pick your moments carefully. The water is running *much colder than normal* for this time of year, sitting at 51°, so a thick wetsuit is non-negotiable.
We kick off on Thursday the 20th with a 5 ft WNW swell at 11 seconds. Combined energy is moderate (621). The wind is cross-onshore though, so it’ll be a bit lumpy and marginal. Not the day to write home about.
Friday the 21st is where we get our first taste of something better. The swell drops to 2 ft but it’s a solid 14-second SW groundswell with light cross-offshore winds. Energy is moderate (410). It stays clean through to Saturday morning, with the wind going fully offshore (12 mph from the SSW) on the 22nd. Waves around 2 ft from the WNW. Decent shape for a savvy surfer on a bigger board.
The standout of the whole outlook lands on Sunday morning, August 23. Glassy conditions. No wind. A clean 4 ft WNW swell at 8 seconds. Combined energy is moderate (252). That’s the window. If you can get out early, you’ll find smooth, fun little waves with nobody hassling you. After noon, the wind swings onshore and it’s game over for the day.
From Monday the 24th onwards, it’s a downward grind. We get a long-period (18 sec) SW swell mid-week, but it’s tiny and crossed up by wind. There’s a slow trickle of clean-ish, cross-offshore mornings on the 26th and 31st, but the swell stays under 2 ft. Late August into early September is mostly marginal.
We get a *glimmer* of hope on September 2nd. Wednesday morning brings an offshore breeze from the south, 12 mph, with a 3 ft WNW swell at 8 seconds. Combined energy is moderate (286). Conditions stay clean through the afternoon. It’s not big, but for this flat run, it’s the next best shot.
After that, into September 3rd and 4th, the swell bumps up to 6 ft to 7 ft from the west, but it comes with heavy onshore winds. That’s a messy, blown-out mess– more of a kite-surfing setup than a clean surf session.
So really, the play is Sunday the 23rd for the glass, and Wednesday September 2nd for a clean little window. Everything else is a wait-and-see.
Stay patient. Rusty.

Information about the Boiler Bay Surf forecast
The above surf forecast table for Boiler Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Boiler Bay can be found by selecting the local surf guide option on the grey menu. Our Boiler Bay 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 (Boiler Bay) 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 Boiler Bay 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.
