The Lowdown
Hey, Rusty here. Let’s break down what’s in the water for Sandtracks over the next couple weeks.
Honestly, it’s a slow patch. The swell stays small and the wind mostly works against us, so there’s a lot of ordinary days ahead. Water temp is around 82°F, which is totally normal for this time of year – nothing unusual.
Starting off Saturday the 12th, we’ve got a tiny 2ft SSW groundswell (16 sec) coming in, only 331 combined energy – pretty weak. With a light E cross-onshore breeze, it’s not the best, but you could maybe get wet if you’re keen.
Sunday the 13th is even smaller in the morning, but the afternoon goes glassy with a 1ft SSW swell (15 sec, 286 energy). That’s your best window for the first week – tiny, but clean and calm.
Monday the 14th through Wednesday the 16th is all cross-shore wind and lumpy surf. Swell runs only 1–3ft, periods are long (15–24 sec), but the wind builds from a light breeze to a fresh breeze, killing any quality. Not worth it.
Thursday the 17th jumps up to 6ft of short-period E windswell (10 sec) with strong energy (up to 1306). But the wind stays cross and fresh, and the swell direction is a poor match for the break. That’s more kite-surfing territory than paddling.
Friday the 18th and Saturday the 19th bring a moderate-sized SSW groundswell (3–4ft, 17 sec, energy over 1000) but again the wind is cross-onshore or cross, with light chop. Just average.
Sunday the 20th morning has a big 7ft E windswell (7 sec) with moderate energy (1001) – but the direction’s wrong and the wind is messy. It drops back to 3ft SSW by afternoon, but still not clean.
The best-looking day lands on Wednesday the 23rd. We get 6ft ENE swell (9 sec) with strong energy (1160) and the wind turns cross-offshore NE, giving us much cleaner faces. That morning session is the real standout – not perfect, but the biggest and cleanest we’ll see in the whole forecast.
After that, Thursday the 24th and beyond drop back to smaller, choppier conditions. Nothing to write home about.
So bottom line: mark your calendar for Sunday afternoon the 13th (tiny but glassy) and Wednesday the 23rd (best size and cleanest wind). Everything else is a skip.
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. If you surf the same spot (Sandtracks) 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 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.
