The Lowdown
Alright, let’s get this out there. It’s a tricky stretch of days ahead for Tandjung-Lefts. The swell is showing plenty of life, but the wind is going to be the main character for a while, and it’s not a friendly one. The water’s at 80°F, which is pretty standard for this time of year, so no surprises there.
To start, the next few days are gonna be a write-off for a clean wave. We’re looking at cross-onshore breezes in the 12-15 mph range, which is just going to chop things up. The swell is there, around 6ft to 7ft from the SSW with a 16-17 second period, but it’s a mess. The energy is moderate, with readings like 2203 and 2020, but it doesn’t matter when the surface is all over the place. This stretch is for the kites, not the surfboards.
We’ll see a little more size on Saturday, still around 7ft, but the wind stays cross-onshore and the conditions remain choppy. It’s not going to be pretty. Sunday is much the same, with 7ft of SSW swell and a cross-on breeze. Still not worth paddling out for a decent session.
Now, here’s where it gets interesting. Monday the 10th is the first real glimmer of hope. The swell jumps up to 10ft and the period stretches out to 18 seconds. That’s a proper groundswell, and the energy is strong, with a reading of 5292. The wind drops to a gentle 9 mph cross-shore breeze, which is the first time we’ve seen anything like clean conditions. This is the standout of the whole window. The size is solid, but it’s a reef break, so it should handle it. It’s advanced-level stuff at this size, but the shape should be there. Tuesday the 11th holds similar size at 10ft, but the wind swings back to cross-on, making it a bit less appealing.
Things back off a touch for the middle of the week. Wednesday and Thursday will have some waves, but the wind is still an issue. We’ll see a peak again on Thursday the 13th with 10ft of S swell, but it’s cross-on and choppy again. It’s a frustrating pattern.
The following weekend and into the second week just doesn’t have that magic. The swell stays in the 5ft to 8ft range, but the wind is almost always cross-onshore, and the conditions are consistently described as poor or marginal. There’s a lot of energy in the water, with readings over 3000 at times, but the quality just isn't there. The periods are a bit shorter too, dropping to 14-16 seconds, which loses some of that punch.
So, the long and short of it is this: the only real window for a quality session is Monday the 10th. That’s the one to keep an eye on. The rest of the run is a battle against the wind. It’s not a blank run, but it’s a grind. Keep the faith, check the forecasts, and be ready to move when that window opens.
