The Lowdown
Alright, Rusty here. Let’s break it down.
The next 16 days are all about Tandjung-Lefts, a consistent advanced reef break that’s fairly exposed to the swell. There’s no surf on offer right now, so we’re looking at a gap until the first real recommendation kicks in. The water temperature is 80°F – that’s about normal for the time of year, so no surprises.
We start on Tuesday afternoon, August 4th, with a 5ft SSW swell running at 14 seconds. There’s a solid moderate wave energy (1045) but the wind is cross-on from the SE at 9 mph, making it fairly choppy. Not great. The next few days are similar – Wednesday the 5th has a 5ft SSW swell, but the wind picks up to 12 mph cross-on, and the forecast is poor. Thursday morning the 6th sees a 6ft SSW swell with a very long period of 17 seconds, but the wind is onshore from the ESE at 16 mph, which is a write-off.
The real standout arrives early on Monday, August 10th. The swell drops to 5ft, but the period stretches to a massive 20 seconds – that’s a proper groundswell. The combined energy is still strong (2629). The wind is cross-on, but it’s a gentle breeze. This is the best wave shape of the run, but remember, a long period like that at a reef break like Tandjung-Lefts can be a bit straight and fast. Still, it’s the pick of the first week.
After that, the swell builds quickly. Tuesday the 11th morning sees a 10ft SSW swell with a 17-second period and strong energy (4461). That’s big – expert territory only. The wind is still cross-on, so it’ll be a messy, heavy beast. Not for the faint-hearted.
The second week is a continuation of the same pattern: solid SSW swell, mostly between 6ft and 8ft, with periods of 15-18 seconds. The wind is persistent cross-on from the SE or ESE, 9-12 mph. The wave energy is consistently strong to very strong (3-digit to 4-digit values). The best bet in the second week is probably Thursday morning, August 13th, with a 8ft SSW swell, 17-second period, and a gentle cross-on breeze. It’s a “marginal” call, but that’s the cleanest you’ll get.
Honestly, if you’re a kite surfer, this setup is way more interesting than paddling. The cross-on wind and consistent, powerful swell will make for good sessions on a kite. For paddle surfing, it’s a battle with the wind every day, and the surf quality is always just on the edge. The real standout is that Monday, August 10th morning – the long period, smaller swell, and lighter wind. That’s the one.
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.

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.
