Alright, Rusty here again, lookin’ at the same stretch for Sandy Beach. And man, it’s a tough one.
We’ve got a big gap of nothing good – from Sunday, July 5th, all the way through the end of the 16-day window. The swell is not the problem. We see waves coming in, but the wind is a constant enemy. It’s a cross-shore from the ENE, blowing 18–25 mph, day after day. That makes for a messy, lumpy cross-chop and just poor conditions overall.
Even when the swell hits a solid 7 ft on the 6th, with combined energy hitting 865 (moderate wave energy), it’s all blown apart. The swell period is short, mostly 7-8 seconds, so it’s weak and choppy. There’s a sweet 0.8 ft SSW groundswell on the 5th with a super-long 18-second period and energy at 861, but with the cross-wind, it’s a total waste.
For beginners, the swell gets over 5 ft from the 6th to the 11th, topping out at 8 ft, so that’s expert territory. But the wind ruins it for everyone. With that constant cross-shore and strong breeze, I’d say this spot is more interesting for kite surfing than paddle surfing right now.
The water temp is a warm 80°, pretty average for the time of year. No help there.
There’s no standout day here. It’s a dry run, plain and simple. Could change, but right now, leave the board at home.
Rusty.

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