The Lowdown
G’day, Rusty here. Let’s be straight with you – the next couple of weeks at Sandtracks are looking pretty average. The wind is the main enemy, blowing cross-shore for most of the run, which is going to chop things up and keep the quality down. We’re looking at a lot of lumpy, cross-shore slop rather than anything clean.
The first few days are a write-off. Tuesday and Wednesday have that fresh cross-shore breeze up to 19 mph, and the sea surface is going to be a mess. We’re talking poor surf conditions with all that chop. The swell is there, around 2ft to 4ft, but it’s not doing anything for us. The combined energy is moderate, but the wind kills it. It’s a frustrating start, no doubt.
Thursday is more of the same. The swell builds a touch to 4ft, but that wind is still cross and fresh, so it’s still lumpy. No good.
Friday, still not happening. The swell drops back to 4ft, and that fresh cross-shore is still on it. We’re just not getting any quality.
Then we get a bit of a tease on Saturday. The wind swings to a cross-offshore from the NE, and the surf cleans up nicely. Swell jumps to 5ft to 6ft, and it’s looking surfable. But the period is only 9 seconds, so it’s a bit weak and crumbly. It’s marginal, but at least it’s not a complete mess. The water temp is about average for this time of year, so no worries there.
Sunday the 16th is the only real standout in this whole window. We’ve got a proper swell filling in, 8ft in the morning with an 11-second period. The energy is strong, way up there in the 2638 bracket. The wind is still cross-offshore, and the waves will be clean. The problem is that at 8ft, this is expert territory – it’s going to be big and powerful. It’s a short window though, as the afternoon sees it back down to 7ft and the wind picks up to 25 mph. If you’re a solid surfer, get out there Sunday morning. This is the one to watch.
After that, it all falls apart again. Monday brings onshore winds and rain, with a storm risk – that’s a complete washout. The swell is still 7ft, but with that wind, it’s going to be horrible.
From Tuesday the 18th onwards, we’re looking at a long, long stretch of poor conditions. The wind stays cross or cross-on, and the swell fades away. We’re talking mostly 2ft to 4ft of weak, short-period slop with no energy. There’s a bit of a pulse around the 26th, with the energy jumping to 1280, but it’s still cross-shore and only marginal. It’s a grim outlook, folks.
So here’s the summary. The only day worth getting excited about is Sunday the 16th, and that’s only for the experienced crew. For everyone else, this looks like a dry spell, and you might be better off finding something else to do. The setup at Sandtracks with the wind and the beach is looking more like a kite-surfing day than a paddle-surfing day for much of this period. Sorry to be the bearer of bad news.
Rusty.

Information about the Sandtracks Surf forecast
The above surf forecast table for Sandtracks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandtracks can be found by selecting the local surf guide option on the grey menu. Our Sandtracks 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.

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 Sandtracks 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.
