The Lowdown
Alright, let’s break it down. Right now, there’s not much to get excited about at Boulders for the next several days – the wind is all wrong, blowing cross-on or cross, and the sea state is lumpy and messy. This stretch from Thursday 30th July right through to the morning of Wednesday 5th August is basically a write-off. You’ve got waves in the water, yeah, but with that fresh southeast wind and a cross-chop, it’s gonna be a frustrating paddle for nothing. Even the moderate breezes on Sunday and Monday just leave a cross-chop you don’t want.
Then Wednesday 5th August afternoon is where things start turning. The wind swings cross-off from the ENE at just 9 mph, and the sea cleans right up. We’re looking at clean, lined up 4 ft swell from the south at 13 seconds. The combined swell energy is solid at 1081 (moderate-strong). It’s not huge, but it’ll be a hell of a lot more fun than what we’ve been dealing with. Crowds can show up here, but with the conditions finally playing ball, it’s worth the paddle.
The real standout, the one to circle on your calendar, is Wednesday 12th August afternoon. The wind goes light offshore from the NNE at 9 mph – glassy offshore, mate. You’ve got a solid 5 ft swell rolling in from the ESE at 9 seconds, and combined energy is 758 (moderate). This is a reef break, so that shorter-period swell should still wrap in nicely and give you some proper shape. Clean, offshore, and consistent – this is the best on offer across the whole outlook.
Thursday 13th August morning keeps the good streak with light cross-off winds and similar 5 ft ESE swell, but it’s a little less certain as it’s further out. Still worth a look if you’re itching for clean waves.
The water temperature is 81°F – bang on average for this time of year, no surprises there.

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.
