The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, it’s a pretty grim start here for the next couple of weeks. We’ve got a long dry spell of surf that just isn’t worth paddling out for. The first week is a write-off for Tandjung-Lefts, with nothing but poor conditions and cross-onshore winds messing up the lineup. From Tuesday the 21st right through to Tuesday the 28th of July, it’s all “poor surf conditions” – choppy, lumpy, and just plain ugly. The wind is a moderate to fresh breeze from the ESE and SE, keeping everything cross-onshore and messy. The swell is there, but it’s not clean enough to ride.
We finally see a slight shift beginning Thursday the 30th of July. The conditions are still only marginal, but the wind drops to a light breeze from the SE, and the swell is a consistent 4 ft from the SSW with a solid 15-second period. The combined swell energy is moderate to strong (1126). It’s not perfect, but it’s the first sign of life. The water is sitting at 81°F, which is about average for this time of year.
Friday the 31st of July stays marginal, with a light cross-shore breeze. The swell drops to 3 ft but the period stretches to a very long 18 seconds from the SSW. That long period groundswell is going to be tricky for a beach break, but Tandjung-Lefts is a reef, so it might find its way in. The energy is still moderate (1053).
The real standout, and the only one worth getting excited about, is the weekend of the 1st and 2nd of August. Saturday the 1st of August sees a 5 ft SSW swell with a 17-second period, light cross-shore winds from the south, and strong wave energy (1624). That’s a solid, long-period groundswell hitting the reef. Crowds are a possibility here, but for a wave this clean, it might be worth it. Sunday the 2nd of August is similar, with a 6 ft SSW swell and a 16-second period, though the wind turns slightly cross-onshore. Still, the energy is strong (1580).
Into the second week, Tuesday the 4th of August brings the biggest swell of the window – 8 ft from the SSW with a very long 19-second period, and very strong energy (5128). That’s expert territory, and the wind is a moderate cross-onshore, so it’ll be a beast. Not for the faint-hearted.
Wednesday the 5th of August is still big, with 7 ft SSW swell, but the wind picks up and the conditions start to slip again. After that, the window closes.
Overall, the best on offer is Saturday the 1st of August at Tandjung-Lefts. That’s your pick. It’s not a perfect run, but it’s the cleanest window we’ve got.
Rusty.

Information about the Tandjung-Lefts Surf forecast

A general guide to surfing at Tandjung-Lefts can be found by selecting the local surf guide option on the grey menu.

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.
