The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got one spot on the radar for this 16-day run: Boulders. This is a solid, consistent reef break that’s advanced territory, so it’s not for the faint-hearted. The water is sitting at a warm 81°, which is pretty much spot on for this time of year – no surprises there.
The real standout is Thursday morning, July 23rd. The stars are aligning. We’re looking at a clean 5ft swell from the south, with a very long period of 18 seconds – that’s proper groundswell, bringing heaps of energy (1722). The wind is a gentle cross-offshore breeze from the ENE at 9 mph, which will keep the faces glassy and smooth. It’s going to be excellent out there. The only catch is it’s for experienced surfers, and you might see a few others out, so don’t expect a total solo session.
The afternoon of the 23rd backs off a touch – the swell drops to 5ft, wind swings to a light cross-on from the SE, and the tide might make things a little tricky. Still, it’s a decent backup.
After that, the wheels fall off for a while. From Friday, July 24th, right through to the end of the first week of August, the wind is a problem. We’re stuck with a persistent cross-onshore breeze from the SE, often blowing 19 to 25 mph, making the surface lumpy and messy. The swell hangs around in the 4ft to 6ft range, but it’s junk. The energy is moderate at best, and the conditions are just poor for a proper paddle session. There’s a couple of days around the 28th and 29th of July where the swell energy picks up (1918 and 1966), but that wind is still onshore, ruining the fun.
Into the second week, from around August 3rd onwards, things get even smaller. The swell drops to around 2ft to 5ft, and the wind stays strong and cross-onshore. The periods are all over the place. There’s a brief pulse on the 6th of August with a 5ft swell from the SW and a very long 18-second period, energy is strong (1812), but the wind is a strong cross-shore from the east at 25 mph, which will just chop it up. Not worth getting excited about.
So, the short story is: grab Thursday morning, July 23rd at Boulders. That’s your one and only true stand-out. The rest of the 16 days is a write-off thanks to the wind. It’s a long gap, more than a week of poor conditions, before things get a bit more interesting near the end, but still not clean.
Rusty out.

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.
