The Lowdown
Alright crew, Rusty here. Let’s break down what’s happening for the next couple of weeks.
Honestly, the outlook for Tandjung-Lefts is a real battle. The whole 16-day stretch is looking at onshore and cross-onshore winds, which will mess up the wave face. There’s no absolute standout session that’s going to be a belter. The water is sitting at a warm 81°, which is about average for this time of year, so you won’t need a thick wetsuit.
The first real chance of anything rideable is on Wednesday morning, July 15th. We’ve got a clear sky and a 6ft SSW groundswell rolling in with a solid 16-second period. The energy is strong, clocking in at (1980). The issue is that wind is onshore from the ESE at 9 mph, which will be a bit bumpy. It’s a marginal call, and the tide might be a factor. This is an advanced reef break, so it’s not for the beginners.
After that, it’s a long dry spell. From Thursday, July 16th, right through to Saturday, July 26th, the forecast is consistently poor. Winds are stubbornly from the ESE or SE, blowing at 12 to 19 mph, keeping the surface choppy and lumpy. Swell sizes hang around 3ft to 6ft, but with the wind, the quality is just not there. The energy is moderate to strong, but it’s all wasted.
The last week of the month offers a tiny glimmer. On Monday morning, July 27th, we see a 7ft swell from the SE, but the period is a short 8 seconds, meaning it’s windswell and not much shape. The wind is still cross-onshore. By Tuesday morning, July 28th, the swell drops to 3ft, but the period stretches to a very long 19 seconds. That’s a proper groundswell, but at a reef break, it might run straight and fast. The wind eases to a light breeze at 6 mph, so it could be the cleanest of the bunch, but the energy is moderate (1030) and the size is small. It’s a marginal, tide-dependent call for the experts.
Honestly, if you’re desperate for a paddle, the Tuesday morning on the 28th is the best of a bad bunch. The rest of the window is looking like a write-off for Tandjung-Lefts with these persistent cross-onshore winds.
Rusty.
