The Lowdown

G’day, Rusty here, and I’ve gotta be straight with you – this 16-day run for Sandy Beach is a tough one. There’s no surf worth paddling out for in the first half of the outlook, and it takes a long time before we even see a flicker of hope. The whole forecast period is a battle with poor conditions, cross-shore winds, and lumpy, choppy water. The first real chance to even think about a session doesn’t roll around until late in the game.

From Tuesday, the 14th of July right through to Friday, the 24th of July, it’s a junk show. Every day is marked by poor surf conditions. The wind is relentless – mostly a fresh cross-shore out of the ENE at 18 to 22 mph, kicking up a lumpy cross-chop. The waves are small, usually under 4 ft, and the swell direction is all over the shop, never matching the optimum ESE that Sandy Beach really wants. The combined energy is moderate, but it’s all wasted with the wind. Not a single good wave in sight.

The only thing that changes is a slight shift on Friday morning, the 24th of July. The forecast bumps up to a “marginal” call, with a score of 1 out of 10. The swell is still tiny at 2 ft from the SSW, with a very long period of 18 seconds, but the wind is a moderate cross-shore at 15 mph. The combined energy is strong at 674, but it’s just not enough to overcome the chop. You’d be scratching for a ride.

We get a better look on Wednesday, the 29th of July. The morning shows a 3 ft swell from the ENE, period 13 seconds, with a light cross-shore breeze at only 6 mph. The water temp is a warm 79°, which is about normal for this time of year. The combined energy is moderate at 469, and it’s another “marginal” call. The afternoon picks up a little, with 4 ft from the ENE and a 12-second period, still with that light breeze. The water temp anomaly is only 0.2°, so nothing unusual there. This is the best on offer, and it’s not saying much. It’s the only period where the wind is light enough to give you a clean-ish face, but it’s still cross-shore, and the break is inconsistent. Crowds are often here, so you might have company, but honestly, I wouldn’t rush.

So, the standout is Wednesday, the 29th of July. The morning session is your best bet. The swell is small at 3 ft from the ENE, the wind is light, and the waves might just be rideable. It’s a long wait for a very average day, but it’s the only window in the whole 16 days where the conditions aren’t totally cooked. The rest is a write-off. Keep an eye on the forecasts, because they can change, but right now, it’s a tough stretch.

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.
