The Lowdown

Alright folks, Rusty here. Gotta be straight with you—this is a tough stretch for Sandy Beach. We’ve got a solid 16-day window ahead, but don’t expect much to write home about for a long while. The first real chance of anything surfable doesn’t show up until Tuesday the 28th, and even that’s a bit of a gamble. Before that, it’s a whole lot of nothing.

The Pattern

Right now, and for the next several days, we’re stuck in a rut. Strong cross-shore winds from the ENE are just mucking up the water. The wave energy is actually moderate to strong (values between 836 and 1297), but it’s all wind-driven, short-period junk with a messy cross-chop. The water temp is sitting at a pleasant 80°, which is totally normal for this time of year, so at least the water feels good while you’re getting skunked. From Thursday the 23rd through Monday the 27th, the surf is either poor or just marginal at best. Don’t bother.

The First Real Glimmer (Tuesday, 28th July)

Alright, Tuesday the 28th is where we start to see a little hope. The morning session still has a moderate cross-shore with a cross-chop, but the swell is starting to build. By Tuesday afternoon, the wind shifts to a cross-offshore from the NNE at 19 mph, cleaning things up nicely. The swell is a solid 6 ft from the ENE, with a moderate period of 13 seconds and a strong combined energy of 1479. It’s still a bit of a gamble, but the clean conditions make it worth a look if you’re desperate.

The Real Standout (Wednesday, 29th July)

Wednesday the 29th is the only true standout in this whole outlook. The morning session is firing—a 10 ft swell from the ENE, with an 11-second period. That’s *big*. The combined energy is a very strong 1898, so there’s plenty of power. The wind is from the north at 16 mph, which is a clean cross-offshore breeze. Now, the big caveat here: the forecast says the swell is too big for this break. At over 8 ft, it’s really only for the experts. The afternoon sees a drop to 7 ft, but the wind swings to a light cross-onshore from the south, which ruins the party. So, if you’re an experienced surfer, this Wednesday morning is your one and only shot at something epic. After that, it’s back to the grind.

The Long, Slow Fade

From Thursday the 30th all the way through to Friday the 7th of August, it’s a real slog. The swell sticks around in the 3 ft to 7 ft range, but it’s almost always hammered by cross-shore winds from the ENE or NE. The energy levels drop off significantly, going from moderate (544) down to weak (314) by the end. The period is often short, between 7 and 8 seconds, which is just sloppy. There are a few marginal moments, like the morning of the 7th of August, with a gentle cross-shore and a 5 ft NE swell, but it’s not worth getting excited about. This is a long stretch of poor to marginal conditions.

Bottom Line

For this 16-day window, there’s only one real standout: the morning of Wednesday, July 29th. It’s a big, powerful swell with clean wind, but it’s expert-only. If you’re not at that level, you’re looking at a lot of frustrating, choppy days. The rest of the time, the setup is so messy and cross-shore that it honestly looks more interesting for kite surfing than paddle surfing. Don’t hold your breath, but forecasts can change.

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.
