The Lowdown

Alright, let me level with you. The next 16 days are honestly a tough watch for proper surf at Sandtracks. We’ve got a solid run of onshore and cross-shore winds with lumpy, choppy conditions that make most of the forecast a write-off for paddle surfing.

The water temp is sitting at 27°C, which is pretty much average for this time of year, so at least you won’t need a thick suit for the few moments it might look okay.

Through the first week, from Monday 10 August up until Friday 14 August, it’s constant cross-shore winds around 25 to 35 km/h and mostly poor surf conditions. The swell is small, only 0.6m to 1.1m, and mostly from the SSW and S. The combined swell energy sits between 389 and 983, which is moderate at best but completely let down by the wind chop. The surf is messy and not really offering much. Thursday 13 August morning has the most size at 1.4m (moderate energy at 1125), but with a fresh cross-shore and lumpy conditions, it’s still a pass.

There’s a brief window on Friday 14 August morning when the wind goes cross-offshore and the surface cleans up, with 1.1m S swell at 14 seconds. It’s marginal but probably the least frustrating session of the early run.

Saturday 15 August and Sunday 16 August see a jump in size. By Saturday morning we’ve got 2.1m from the east at 10 seconds, building to 2.4m from the east at 12 seconds in the afternoon. The wind is cross-offshore and clean, so the surface will look good, but the energy is very strong (1246 to 1805). That east swell direction isn’t the best match for Sandtracks, as it favours an SSE optimum. Sunday 16 August pushes up to 3.5m to 5.5m from the ENE with onshore wind and risk of thunderstorms. That’s too big and blown out – only for very experienced chargers if anyone even considers it.

The standout window in the whole forecast is hard to call, but if I’ve got to pick one, it’s Saturday 15 August morning. Clean conditions from a cross-offshore northeast breeze, 2.1m of east swell with steady 10 second period, moderate-to-strong energy. Crowds are possible as it’s often busy, but the quality is only marginal for Sandtracks given the direction mismatch. Still, it’s the closest we get to a proper session.

From Monday 17 August onward it’s back to small, wind-affected, and mostly poor surf. There’s a brief lift on Tuesday 25 August morning with 1.1m S swell at 19 seconds, long period groundswell, and moderate-to-strong energy (1463). But the cross-shore wind is still there at 35 km/h, creating a lumpy mess. That long period swell would work better at a reef or point, but Sandtracks is exposed and will be breaking straight in those conditions.

In short, it’s a lean 16 days. There’s one half-decent clean morning on Saturday 15 August. If you’re desperate, that’s your window. Otherwise, it might be more interesting for kite surfing on the bigger days when the wind is solid.

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.
