The Lowdown
Alright, Rusty here, and I’m looking at Tandjung-Lefts for the next 16 days. Man, it’s a rough one. The wind is stuck cross-onshore from the ESE and SE almost every single day, keeping the surface choppy and messy. Water temp is about 81°F, which is normal for this time of year.
The first week, from Thursday, July 16, to July 22, is a total bust. Swell is from the SSW, mostly 3 to 4 feet, with periods of 13 to 15 seconds, but that cross-on wind kills it. Combined energy is moderate, like 992 to 720, but it’s all "poor surf conditions." No scores worth a mention. Nothing.
Then July 20, Monday morning, we get a bump—swell hits 7 feet, with a 17-second period, and combined energy spikes to 2390. That’s strong, but the wind is still cross-onshore, so it’s a lumpy, blown-out mess. Only for experts, and the quality is poor.
The second week, July 21 to July 27, stays in the same rut. Swell drops to 3 to 6 feet, periods shorten, and the wind is relentless. Combined energy is moderate, like 640 to 548. Still all "poor surf conditions."
At the end of the run, from July 28 to July 31, the wind eases to a gentle breeze from the SE, 9 mph. Swell is around 3 to 5 feet, with periods of 14 to 17 seconds, and combined energy is moderate to strong, like 1020 to 1851. Conditions flip to "marginal surf forecast or questionable tide conditions," with scores of 1 or 2. The last day, July 31, has a very long period swell of 22 seconds from the SSW, combined energy of 1851, which is interesting for a reef, but still cross-onshore wind.
The best? July 28, Tuesday afternoon. Swell is 5 feet from the SSW, 14-second period, wind is a gentle 9 mph from the SSE. That’s the lightest wind of the whole period, still cross-onshore, but it’s the closest to clean you’ll get. Combined energy is 1509, score is 2. That’s the best of a bad bunch. Also July 31 has a 3-foot swell with a 22-second period, combined energy 1851, but again, cross-onshore wind.
Crowds at Tandjung-Lefts are sometimes an issue, but with conditions this poor, it’ll be quiet. The break is consistent and fairly exposed.
A long, dry run. Hang tight, check back later. Forecasts can change.

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.
