The Lowdown

Alright, Rusty here. Let's get into it.

We're looking at a pretty grim stretch ahead for Tandjung-Lefts. This is an advanced reef break that needs a good southerly swell and clean conditions, but we're just not getting the combo. The wind is locked in from the ESE to SE, which puts it straight into cross-onshore territory for this spot, and it's blowing a solid 12 to 19 mph most days. That means the surface is going to be choppy and lumpy, and the wave quality is shot. The forecast is dominated by poor surf conditions, with the combined swell energy bouncing between moderate and strong, but it's all wasted on the wind.

For the first week, from Sunday the 19th right through to Friday the 24th, it's a write-off. The swell is coming from the SSW, but the cross-onshore wind is just ruining it. The period is decent, often 13 to 17 seconds, which means there's groundswell energy in the water, but the wind chops it all up. We're talking about combined energy values from 467 to 2046, so there's plenty of push, but it's ugly. The water temperature is about average for this time of year, but that's small comfort.

The only glimmer comes on the morning of Saturday the 25th of July. The wind shifts to being directly onshore from the ESE, and the swell is still solid from the SSW at 4 ft with a period of 15 seconds. The forecast still says "poor surf conditions" but the wind state is listed as "unknown," which could mean it's glassing off for a moment. The combined energy is a strong 1536, so there's power. It's a gamble, but if that wind lays down, this advanced reef has the potential to offer a few good ones. Don't get your hopes up for the afternoon, though, as the wind swings back to cross-on.

After that, it's back to the same story. The wind returns to a cross-onshore ESE-SE flow for the rest of the month. The swell height does push up to 7 ft on the 1st of August, but with a 19 mph cross-onshore, it's just a messy, lumpy affair for experts only. The period drops to 8 seconds on the 26th, which is a short period windswell, offering no shape. The final morning on Monday the 3rd of August is classed as marginal, with a 6 ft SSW swell, but the cross-onshore wind is still there. It's a long stretch of poor to marginal surf, with no real standouts.

Rusty, signing off.

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

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.
