The Lowdown

Alright crew, Rusty here. Let’s suss out what Sandtracks is doing for the next two weeks or so.

I’ll be straight with you – this is a grim outlook. The whole 16-day window is a struggle. We’ve got lumpy, wind-affected junk for most of it, and the swell is tiny and messy early on. The first few days are a total washout with poor surf and strong cross-onshore wind. It’s a rough start.

The best chance to get wet is on Wednesday afternoon, September 9th. The swell drops right down to 3ft, but the wind goes glassy, which is a huge win. The swell is a long-period 13 seconds from the SSW, so it’s got some energy (combined energy of 368), and those clean conditions will make it super user-friendly. The water temp is about 81°, which is pretty standard for this time of year – nothing unusual. The offshore direction is NNW, so that glassy period is a rare treat. It’s a reef break, so it’s for the intermediate crew, but it could be a nice, mellow session.

After that Wednesday, it’s back to the grind. Thursday the 10th through Monday the 14th is a gap of several days with no real recommendations, just tiny, junky swell and cross-shore winds. The swell is tiny, often under 2ft, and the wind is just never right. The combined energy drops to three-digit figures, showing weak to moderate wave energy.

We do see a bit of a pulse around the 15th and 16th of September, with the swell picking up to 3ft from the SSW and a meaty period of 18-20 seconds, and the combined energy jumps back up to the 600s (moderate). But the wind is a persistent cross or cross-onshore, which will keep it choppy and bumpy. It’s just not clean enough to get excited about. The long period from the SSW is a nice groundswell, but with the wind on it, Sandtracks will be a bit of a mess.

From the 17th through to the 23rd, we’re into fresh breeze territory with winds from the ENE, often 18-22 mph. The swell stays small, between 2ft and 4ft, but the wind is going to kill any chance of quality. The combined energy gets up to 943 (moderate) but it’s all wind chop. This setup is honestly looking more interesting for kite surfing than paddle surfing, given the consistent cross-shore wind and the small, messy waves.

The standout here is that Wednesday afternoon, September 9th. It’s the only window where the stars align for a clean, glassy session. The rest of the run is a long wait for the wind to back off. Keep an eye on the forecasts, but don’t hold your breath.

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.
