The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – this is a tricky outlook for Tandjung-Lefts. There’s a heap of swell on the charts, but the wind is a real bastard for most of the run. This is a reef break, so we’re dealing with a consistent, advanced wave, but it’s going to be a battle against the chop for much of the next two weeks.

The real story here is that we’ve got a long period SSW groundswell, with periods pushing 16 to 18 seconds, pumping in a lot of energy. The combined swell energy is often in the thousands (3202, 3607, 3174), which is strong to very strong. But the wind is hammering it from the SE and ESE, giving us a cross-on mess. The water temp is sitting at 80°F, which is about normal for this time of year – nothing to get excited about there.

We kick off on Wednesday, 19 August, with a 7ft SSW swell, but that cross-on breeze from the SE at 9 mph is already making it choppy. That theme continues all through the week and into the next. Thursday morning, 20 August, sees a 8ft swell, but it’s still cross-on and choppy. The swell stays solid, around 5ft to 7ft, but the wind is persistently from the SE or ESE, 9-12 mph, making it a messy, frustrating paddle.

Honestly, most of the first week is a write-off for a clean wave. The models are calling it marginal or poor, and I’d have to agree. On Saturday, 22 August, it’s even worse – 16 mph winds and poor conditions. For a reef break, that’s just not fun.

There’s a light at the end of the tunnel, though. The standout from this entire forecast is the weekend of 29-30 August. On Saturday, 29 August, the wind finally swings to the SSW at 6-9 mph, giving us a clean cross-off breeze. The swell is around 5ft to 6ft from the SSW, with a period of 14 seconds. It’s not the biggest, but the quality will be there. The combined energy is moderate (1230, 916), but with clean conditions, this is your best bet. Tandjung-Lefts will be offering some proper, lined-up waves.

After that, another gap of poor conditions. The wind goes back to cross-on on the 30th and 31st, with a 4ft to 5ft SSW swell. There’s another pulse of bigger swell (7ft to 8ft) from the SSW on the 1st and 2nd of September, but the wind is back to being a problem – cross-on from the ESE at 12 mph. The models are still calling it marginal, so it’s not a guarantee.

In short, for the advanced surfer, the 29th of August is the one to circle. The rest you can probably sleep in for.

Rusty.

Information about the Tandjung-Lefts Surf forecast

The above surf forecast table for Tandjung-Lefts provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tandjung-Lefts can be found by selecting the local surf guide option on the grey menu. Our Tandjung-Lefts 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.

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 Tandjung-Lefts 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.
