The Lowdown
Right, grab a coffee, let’s have a look at what’s coming our way for the next couple of weeks at Sandtracks.
To be honest, the start is a bit of a write-off. We’ve got nothing worth paddling out for until around the middle of next week. That’s just how it goes sometimes – the ocean is in a bit of a grumpy mood, with strong cross-shore winds and messy conditions dominating the first week. You’d be fighting a losing battle trying to get a clean one.
The only real standout in this whole 16-day window is shaping up for Sunday, the 16th of August. That morning, the wind swings clean offshore from the north at 9 mph, and we’ve got a solid 6 ft swell arriving from the ENE. The period is a punchy 11 seconds, and the combined energy is way up there at 1984 – that’s proper, strong energy. The water temp is about average for the time of year, so just your usual thin wetsuit or spring suit. Sandtracks is a reef setup, and with a long period swell like that coming out of the ENE, it should line up nicely. This is the morning to be there. The afternoon gets even better: the swell bumps up to 7 ft from the east at 13 seconds, with the energy hitting 2029, and a moderate offshore from the NNW at 12 mph. That’s excellent, heavy surf for experienced surfers only. Beginners, leave this one alone – anything over 8 ft is expert territory, and this is close. It’s going to be a clean, powerful day. Crowds are often a factor here, so expect company.
Before that, Saturday the 15th gives a little glimmer. The morning has 5 ft from the east at 9 seconds with a cross-off shore wind from the ENE at 19 mph. It’s clean, but the swell is short-period, so the waves won’t have much push. The afternoon is slightly better with 6 ft ENE at 10 seconds and a cross-off from the NE. It’s rideable, but nothing like that Sunday.
After the weekend, things drop off quickly. Monday the 17th is messy with cross-on wind, and from Tuesday the 18th onward, the size fades right away. There’s a tiny window on Tuesday afternoon with a glassy 1 ft swell from the SSW, but you’d be lucky to get a wave. The following week is a long, flat stretch of poor conditions with strong cross-shore winds and tiny, weak swell. It’s not worth the drive.
So, it’s a waiting game. Sunday the 16th is your day. The rest is a story of patience.

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.
