Tengan Surf Forecast and Surf Report

Alright, let’s get into it. It’s Rusty here. Not gonna lie, we’re in for a bit of a dry spell to kick things off.

Right off the bat, for the first few days, Tengan is getting absolutely hammered by onshore winds and messy conditions through the 1st and 2nd of September. The swell is there, around 6 ft to 7 ft from the east, but with that wind it’s just blown out and ugly. The combined energy is moderate to moderate-strong (485 to 675), but it’s all for nothing with the wind.

We finally get a window on the afternoon of Thursday, 3rd September. The wind swings offshore from the WNW at 15 km/h, and the swell drops to a clean 4 ft from the east with a period of 10 seconds. Combined energy reading is 288 (weak to moderate), so it’s not a big day, but it’s clean. That’s the first real chance for a wave.

Friday morning the 4th is cross-off with a tiny 4 ft from the north, but the real gem looks like Friday afternoon. Wind goes light offshore from the west at 10 km/h on a dropping 3 ft NNE swell. Glassy conditions are possible early Saturday the 5th, with a 4 ft north swell and that ENE wind going glassy. The combined energy that morning is 253 (weak to moderate). Not epic, but for consistency, that might be the best window early on.

After that, it all falls apart. From the 6th through to the 10th of September we get a long stretch of strong cross-onshore or messy winds, and the swell either drops or gets too short period. The 9th shows a 12-second easterly swell (groundswell) at 3 ft, but the wind is a fresh cross-onshore 30 km/h—completely unsurfable. There are a few clean-looking cross-off windows on the 10th, 11th, and 12th of September, but the wind is howling at 35 to 40 km/h. The wave faces will be clean, but you’ll be paddling into a strong breeze. Not recommended unless you’re tough. The 12th afternoon turns choppy again.

Then from the 13th into the 14th, onshore winds and cross-onshore chop ruin things again. Even a 5 ft ENE swell on the 14th afternoon doesn’t save you.

The real standout, and I mean the one that grabs you by the collar, is that last record: Tengan on the afternoon of 16th September. This is a massive pulse. We’re looking at a 23 ft north swell, with a 10-second period. The combined energy is a monstrous 19,158 (very strong). Wind is cross-shore at 20 km/h, but at that size, it doesn’t matter as much—this is solid expert territory. Anything over 8 ft is for experts, so 23 ft is huge. It’s a reef break, so it will handle the size, but the period is moderate at 10 seconds. This is a big, powerful, critical wave. The score for that afternoon is high, and it’s the only real jaw-dropper in the whole 16-day window.

Earlier that morning on the 16th, there’s a 15 ft swell (combined energy 2,558 – strong), also cross-shore and challenging.

Water temp is about average at 83°F with a tiny anomaly, so nothing unusual there.

So, to sum it up: it’s a slow start with a few clean but small windows around the 3rd and 4th/5th of September. After a long gap of poor conditions, the real payoff is the 16th of September, where Tengan turns into a big-wave beast. That’s the one to circle on the calendar.

Stay patient.

Rusty.
