The Lowdown
Alright folks, Rusty here. Let’s get real about what’s coming up for Big Rock over the next couple of weeks.
To be straight with you, the outlook is a tough one. There’s a bit of a bright spot right at the start, but then we’re looking at a long stretch of flat to tiny junk. The water is sitting at 74°, which is a full 7° warmer than usual for this time of year – that’s very unusual, and you’ll feel it when you paddle out, almost like bathwater.
The only real chance to get wet comes in the first few days. Tuesday the 28th of July is your best bet. We’ve got a solid SW groundswell pumping in at 4ft with a long 17-second period. The combined energy is strong, sitting at 1039, so there’s plenty of push. The wind is a bit of a bummer though – a cross-onshore breeze at 9 mph, so it’ll be a little choppy and won’t look its best. Still, that’s the peak of the run. As the week goes on, the swell drops fast. Wednesday morning (29th) is still rideable at 4ft and 16 seconds, but the energy is starting to fade (949) and the cross-onshore wind sticks around.
Thursday the 30th sees a drop to 4ft, and by Friday the 31st it’s hanging on at 4-5ft but the period has dropped to 13 seconds, so the quality is going. The morning winds are light and offshore, so those sessions might be clean, but the wave size is just a shadow of Tuesday.
Then, from Saturday the 1st of August all the way through to the end of the forecast on the 12th of August, it’s pretty much a write-off. We’re looking at swell heights below 3ft, often dropping to 1ft to 2ft. The combined energy plummets to the 100-300 range, which is weak. The wind is mostly light or gentle cross-onshore, but with waves that small, it’s just not going to break properly. The conditions are consistently labelled as “poor” or “marginal.” There’s a solid 12-day gap with no real surf on offer.
So, to sum it up: if you’re desperate, get out on Tuesday the 28th of July. It’s the only day with a real swell. After that, pack the longboard away and pray for a change in the forecast.
Rusty, signing off.

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