The Lowdown
Alright, folks, it’s Rusty here, looking at the next couple of weeks. We’ve got a bit of a mixed bag, but the real story is that the window for a good session is real tight at the start, and then we’re looking at a long stretch of messy, wind-affected stuff. The only real standout is a brief, clean moment on Monday afternoon.
The first swell on offer rolls in on August 3rd. Monday afternoon at Boulders is looking like a real treat. We’ve got a 3-foot swell, but it’s a clean SW groundswell coming in with a solid 14-second period, packing moderate energy (773). The wind is a light 15 km/h from the NE, so it’s a clean cross-off breeze. The water is a warm 81°, which is about average for this time of year. This is your best chance, and it’s a standout. Just be aware that crowds are possible here.
Now, that’s the high point. From Tuesday morning, August 4th, things start to fall apart. The wind cranks onshore and stays there for the long haul. We get a few days of bumpy, cross-onshore slop with the wind building from 15 km/h right up to a near gale. The swell sticks around, but it’s brutal. By Thursday the 6th, the swell climbs to 7 feet out of the SSE, but with a 22 km/h wind, it’s just a lumpy mess. On Friday the 7th, it’s 8 feet from the SSE, but the wind is a strong 25 km/h, making it a total write-off for the experts only.
The weekend of the 8th and 9th is a write-off too. The wind hits 31 km/h, the swell is 10 feet, and it’s blown out. The setup is so rough, it’s looking more interesting for the kite surfers than paddle surfing.
We then have a solid week of the same story. From the 10th through to the 17th, the wind is relentless, mostly from the ESE, and it’s either cross-shore or cross-onshore with a nasty chop. The swell periods are short, between 8-10 seconds, and the energy is high but all out of control. There’s a brief moment on the 15th with a 4-foot, 16-second SW groundswell that looks promising, but it’s a weekend and the wind is still pushing it around.
The tail end of the forecast, on August 18th, shows a 10-foot swell from the SE coming in, but it’s still cross-shore with a moderate breeze. The forecast is marginal at best, so don’t get your hopes up for that.
So, bottom line: get out on Monday the 3rd if you can. The rest of the forecast is a long, windy slog. It’s a tough run.

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