The Lowdown

Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for Sandy Beach, so don’t get your hopes up right away.

We’ve got a real dry spell on our hands. Looking at the whole 16-day window, the surf is mostly a no-go. The first few days are a write-off, and after that, it’s a long stretch of poor conditions. You’re looking at a gap of nearly a week from the start where there’s just nothing worth paddling out for.

The first hint of anything rideable won’t come until Tuesday, July 28th. Even then, it’s marginal. Tuesday morning, the swell is 7 ft from the East, with a period of 13 seconds. That’s some decent energy, with a combined energy of 1825, but it’s a bit of a beast. Over 5 ft, so it’s getting too big for the beginners. The wind is a cross-offshore from the North-Northeast at 15 mph, which will keep it reasonably clean. Tuesday afternoon stays similar with 8 ft East swell, but the wind picks up a bit.

If you’re an experienced surfer, Tuesday morning might be your only real look. The water temp is a warm 80°, which is pretty much bang on average for this time of year. That’s about the only positive.

After that, it turns ugly. From Wednesday the 29th onwards, the wind swings onshore and the quality drops off a cliff. We get a mix of cross-onshore and strong cross-shore winds, with the swell getting shorter and messier. The energy drops, and the conditions are just lumpy, choppy, and poor. By Friday the 31st, the wind is howling from the East-Northeast at 25 mph, and the swell is 7 ft with a short 8-second period. That’s a nasty combo. For the beach-and-reef setup at Sandy Beach, with that strong cross-shore wind and chunky, short-period swell, this setup looks more interesting for kite surfing than paddle surfing.

The second week doesn’t offer any relief. It’s a relentless run of poor conditions through the 1st of August all the way to the 9th. The swell stays between 4 ft and 7 ft, but the wind is always a problem, and the periods are short. There’s a brief blip on the 10th and 11th of August with a tiny, long-period south-southwest swell (2 ft, 16 seconds), but that’s not going to do anything at this exposed beach. It’s a classic case of a blank run for the area.

So, for the standouts, it’s really just that Tuesday morning window. If you’re keen and experienced, you might get a few. Otherwise, give it a miss.

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.
