The Lowdown

Alright, Rusty here. Let's talk about what we've got coming up at Sandtracks.

It's a bit of a tough stretch ahead, to be honest. The next week or so is looking pretty marginal, with a lot of cross-shore winds and lumpy conditions messing up what little swell there is. You're going to have to be patient. The water is sitting at a warm 81°, which is about average for this time of year, so at least you won't be freezing while you're waiting.

The first few days are a write-off. Thursday the 10th through to Monday the 14th are all showing poor surf conditions, with small swells and that persistent cross-shore breeze making a mess of things. There's a bit of energy hanging around, like on Thursday morning with a combined energy of 589 (moderate), but the 2ft SSW groundswell with a 16-second period is just going to look ugly in that cross-chop.

We get a slight pulse mid-week. Tuesday the 15th morning shows a bit more promise with the swell pushing up to 3ft from the SW with a nice long 20-second period. The combined energy climbs to 623 (moderate), and while the wind is still cross-shore, it's only a gentle breeze, so it might just be rideable. That's probably the best of a bad lot for the first week. Wednesday the 16th afternoon sees the swell hit 3ft and the energy jump to 1002 (strong), but that's accompanied by a fresh, lumpy cross-shore wind, so it'll be a challenge.

Then things get a bit more interesting, but not necessarily better. From Thursday the 17th, the swell sizes start to climb, but so does the wind. Thursday afternoon sees a 6ft ENE windswell with a short 9-second period and a strong breeze. That's a lot of energy (1548 – very strong), but it's going to be a messy, blown-out situation. Honestly, with that much wind and a beach setup, those days might be more fun on a kite than a paddleboard.

The real standout, and the one that has me a little buzzed, is looking like Wednesday the 23rd afternoon. It's over a week away, so take it with a grain of salt, but the forecast is calling for glassy conditions. Literally "glassy". The swell drops back to a clean 2ft from the SSW with a long 19-second period, and the combined energy is a solid 723 (moderate). That long period groundswell will wrap in nicely at this reef setup, and with the wind dying to nothing, it should be clean and offering some nice lines. That's the session to aim for, but as always with long-range forecasts, keep your fingers crossed.

After that, it's back to the cross-shore grind for the final days, with moderate energy but messy conditions.

So, there you have it. A lot of waiting for one golden, glassy afternoon. Stay patient.

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.
