Alright, folks, Rusty here. Gotta be straight with you – if you’re looking for a classic paddle sesh, this forecast is a tough one to swallow.
For the next couple of weeks, Sandy Beach is going to be a no-go for comfortable surfing. The wind is locked in from the ENE, blowing cross-shore at 18 to 25 mph practically every single day. That means the ocean’s going to be a bumpy, lumpy mess with cross-chop. The wave heights bob around from about 3 ft all the way up to 7 ft, but the quality just isn’t there for a good ride.
Even when there’s a bit of size, like a 7 ft swell on Monday, July 6th, it’s short period windswell (only 7 seconds) and it’s getting torn up by that strong breeze. The combined energy hits 847 early on, and we see high numbers like 976 later, so there’s power in the water (moderate to strong wave energy), but it’s raw and messy. This is shaping up to be more of a kite surfing show than a surfing one.
The water temp is sitting at 80°F with a tiny anomaly of 0.9°F, so it’s about average for this time of year. Not that you’ll be in the water long on most days unless you love getting chopped up.
Because the surf condition is described as "poor" on every single entry across the entire 16-day window, there are honestly no standout days to recommend. A big blank run like this is pretty tough for the area. Don’t lose all hope – forecasts can shift, and this run of lumpy conditions can’t last forever. But for now, keep your board in the car and wait for a cleaner day.
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.
