The Lowdown

Alright folks, Rusty here. Let’s dig into this forecast for Sandy Beach. We’ve got a pretty long stretch of time ahead, but honestly, it’s a story of persistence over quality. The first few days are a write-off, but there’s a small window of hope if you’re patient.

Right off the bat, the water temp at Sandy Beach is sitting at 80°, which is pretty much bang on for this time of year – nothing unusual there.

The opening days from Wednesday the 22nd right through the weekend are just not worthwhile. We’re looking at a small 2ft to 2ft swell from the SSW with a moderate combined wave energy (872 to 1004), but the wind is a fresh onshore breeze from the ENE, blowing straight across or onshore, and it’s got the ocean all lumpy and crossed up. The wave comment says it all: poor surf conditions. There’s nothing to get excited about here.

Come Friday the 24th, the swell actually bumps up to a solid 7ft to 7ft from the ENE, but it’s short-period wind swell, only 7 seconds. The energy is strong (1091 to 1067), but that wind is still a fresh to strong cross-shore from the ENE, making for a messy, lumpy sea. That’s more of a kite-surfing setup than a paddle-surfing one. This continues through Saturday the 25th, with a mix of that short-period ENE swell and a long-period 18 second SSW groundswell on Saturday afternoon, but the wind stays cross and messy.

Sunday the 26th sees a slight improvement in the wave comment to “marginal,” with a 3ft to 4ft swell and a long period of 15 to 16 seconds. The energy is high (1236 to 1321), but the wind is still a fresh cross-shore, so you’re dealing with a lumpy cross-chop. It’s not good, just a little less bad.

The best on offer looks like it’ll be around Wednesday the 29th of July. On Wednesday afternoon, we get a 7ft swell from the ENE with a period of 11 seconds. The combined energy is strong (1492), and the wind finally shifts to a moderate cross-offshore breeze from the NNE. The wave comment even says “clean.” For Sandy Beach, that’s the standout window. The water will be clean, the swell is a decent size, but keep in mind that 7ft is getting into expert territory for a beach break, especially with that moderate wind. The break is exposed to the ESE swell and the direction is ENE, so it’s not a perfect match, but it’s the best we’ve got.

After that, it drops back into poor or marginal conditions. Thursday the 30th has a light S wind, but it’s cross-on, and the swell drops to 5ft to 6ft. The rest of the run into the first week of August is dominated by a fresh cross-shore wind from the ENE, with swells ranging from 3ft to 7ft, but the period is short (7 to 8 seconds) and the conditions are lumpy and choppy. The energy drops off significantly (down to 314 to 461 range) by the 31st.

There’s a late hint of something on Wednesday the 5th of August, with a 8ft swell from the ENE and a 13-second period, giving a very strong energy of 2167. But the wind is still a fresh cross-shore, and it’s rated as marginal. It’s a long way out, so keep an eye on it, but don’t bank on it.

So, to sum it up: the first week is a total bust. The best chance for a clean, decent-sized wave is Wednesday the 29th of July. After that, it’s mostly a choppy, cross-shore mess. Sandy Beach can be fairly consistent, but this run is a test of patience. The forecasts can always change, but for now, that Wednesday afternoon is your only real shot.

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.
