The Lowdown

Alright, Rusty here again, same deal but in feet and miles per hour. Sandy Beach is looking rough over the next couple of weeks. Normally this spot is fairly consistent, but we’ve got a long stretch of poor conditions. The wind is stuck out of the ENE, blowing cross or cross-onshore most days, tearing up the surface. The swell is mostly short-period windswell from the east, with a few longer-period pulses from the south that bring better energy but still get chopped up.

From Sunday 19 July through Friday 24 July, it’s all zeros – no surf worth mentioning. Swell heights range from 2 ft to 8 ft, but the wind is strong (19–25 mph) and cross, making everything lumpy and messy. The combined energy on Thursday 23 July morning hits 1466 (moderate energy), but the onshore wind makes it ugly. Not worth paddling out.

Saturday 25 July morning is the first marginal day – score of 1. Swell 6 ft from ENE at 8 seconds, fresh cross wind 22 mph. Still lumpy, but rideable if you’re keen. The rest of that day and into the next few days stay marginal with scores of 1. Sunday 26 July morning has a 3 ft, 17-second swell from the east – nice long period, but the wind is still cross at 19 mph. The energy is strong (1353), but the chop ruins the lines.

The one standout – and it’s not much – is Wednesday 29 July morning. Score of 2, the best of the whole period. Swell 6 ft from ENE at 12 seconds, moderate breeze 16 mph cross-shore. Combined energy 1075 (moderate). Still not clean, but the wind is lighter and the period is decent. It’s the most promising session, but it’s still marginal. The break is a beach and reef setup, so the longer period might work on the reef, but the cross wind keeps it bumpy. Crowds are often here, so expect company even on a so-so day.

After that, it drops back to poor. Tuesday 30 July through Monday 3 August – all zeros or low scores. Swell fades, wind stays cross. The last few days have some 14–16 second ESE swell, but the energy is weak (under 1000) and the wind is still fresh. Not worth it.

So, overall: a tough 16 days. The best bet is Wednesday 29 July morning, but don’t get your hopes up. It’s the kind of stretch where you either stay home or take what you can get. The break is fairly consistent, so it won’t stay this bad forever – forecasts can change. But right now, this is a rough run.

Rusty out.

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.
