The Lowdown
Righto, Rusty here. Let's take a look at what we've got for the one spot in the zone over the next couple of weeks.
Look, I'm not gonna sugar-coat it. The outlook for Tandjung-Lefts is a frustrating one. We've got a solid, persistent pulse of SSW groundswell running the whole time, with most days seeing 5ft to 7ft waves, and some serious energy behind it – we're talking combined swell energy figures regularly up in the 1500 to 2300 range, so there's plenty of power. The problem is the wind. For the bulk of this run, it's locked in from the ESE or SE at 9 to 16 mph, which is a cross-on direction for this reef. That means the wave faces are going to be chopped up and messy, and the forecast notes are telling a sad story of "poor" or "marginal" conditions all the way through to the end of the month.
Friday the 11th kicks off with a 6ft SSW swell (16-second period), but the 12 mph ESE cross-onshore breeze just ruins it. Saturday is much the same story. This pattern basically holds for the entire first week. We get a bit of a break in the wind strength around Wednesday the 16th afternoon with only 6 mph, but it's still cross-on, so only a slight improvement. Don't get your hopes up.
The standout window, the one that actually looks worth setting an alarm for, is Tuesday the 22nd of September into Wednesday the 23rd. On Tuesday morning, the wind shifts to a true cross-shore from the SSE at 9 mph. The swell is still a solid 6ft from the SSW (14-second period), and the combined energy sits at 1406. That cross-shore breeze is a huge deal for this break – it should clean the lines up considerably, making that powerful reef wave much more rideable. Tuesday afternoon gets even better with the wind dropping to a light 6 mph from the South, also cross-shore. It's not the most perfect offshore, but for this forecast, it's as good as it gets. Wednesday the 23rd morning drops a little in size but holds a clean cross-onshore with a 16-second period, keeping it in the mix.
Now, a word of warning: Tandjung-Lefts is an advanced reef break, and when you've got a 6ft to 7ft SSW groundswell wrapping in, it is going to be a serious, thick, and powerful wave. This is not beginner territory. With a 14 to 16-second period, those sets will have plenty of punch. Being a reef, the shape should be there, but it'll be a proper challenge. Also, the crowds are noted as "sometimes", so you might have some company, but it shouldn't be a circus.
From Thursday the 24th, the wind looks like it wants to go back onshore again, though the size remains. The very end of the run, Saturday the 26th, has a big 6ft to 7ft SSW swell with a 17-second period and energy up at 2383, but once again the cross-onshore wind kills it. Short version: sit tight, wait for that cross-shore window around the 22nd and maybe 23rd, and if you're an experienced surfer, that's your time to paddle out.
Stay safe, and keep an eye on the sky.
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. If you surf the same spot (Tandjung-Lefts) 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 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.
