Tengan Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a long, hard look at what’s coming our way over the next couple of weeks. I gotta be straight with you from the jump: this is a rough stretch. We’re looking at a long, frustrating run of onshore gunk and stormy wind, with only a tiny flicker of hope right at the very end. It’s gonna be a test of patience.

We start off on Saturday, August 29th, and straight away it’s a no-go. Tengan’s got a 4.3 ft swell from the ESE, but with a short period of 8 seconds and a cross-on breeze hitting 15.5 mph, it’s just choppy and poor. The combined swell energy is weak at 193, and it doesn’t get any better. That afternoon, the wind picks up to 18.6 mph, making it even lumpier.

Sunday the 30th is more of the same: onshore wind, a short-period 3.9 ft to 4.9 ft swell from the east, and the energy bumps up to 256 on Sunday afternoon, but the wind is still blowing 18.6 mph right on it. It’s a mess.

Then we hit a real stormy patch. From Monday, August 31st, right through to Wednesday, September 2nd, we’ve got risk of thunderstorms and howling wind. Monday morning sees an 8.2 ft swell from the east with a 9-second period, but the wind is a brutal 28 mph onshore. The combined energy spikes to 1098 (strong), but that’s just raw power with no shape. Monday afternoon pushes 9.8 ft swell and 24.9 mph cross-on wind – that’s big, wild, and dangerous, only for experts, and even then, it’s not clean. Tuesday and Wednesday stay in the same ugly pattern, with 3.9 ft to 6.9 ft swells, short periods, and strong cross-onshore winds. The wave energy is moderate (245 to 566), but the quality is zero. This setup is more interesting for kite surfing than paddle surfing.

Thursday, September 3rd, finally shows a glimmer of improvement. The wind swings cross-offshore from the SSW and SW at 18.6 mph, giving us clean conditions. The swell drops to 4.6 ft on Thursday morning and 3.0 ft in the afternoon, with a period of 9 to 10 seconds and moderate energy (394 then 133). It’s clean, but the swell is weak and inconsistent. It’s surfable, but barely worth the paddle.

Friday, September 4th, is the first and only genuine standout in this whole forecast. The wind goes light, 6.2 mph cross-offshore from the SW, and the conditions are clean. We’ve got a small 2.6 ft swell from the east with a 9-second period. The combined energy is low at 110-118. This is a tiny, clean wave – perfect for a longboard or a foamie, and a great session for beginners. The water temperature is about average for the time of year. It’s the only window where it’s actually pleasant, even if it’s small. Crowds are possible at Tengan.

After Friday, it’s back to the grind. Saturday, September 5th, goes flat with 2.0 ft to 3.0 ft onshore junk. Sunday the 6th has a 4.3 ft to 4.9 ft swell from the east, but the wind is cross-onshore again, making it choppy. The energy is moderate (202-298), but the quality is poor.

Then we get another blast of wind. Monday, September 7th, and Tuesday, September 8th, bring strong to gale-force winds, with a 6.6 ft to 6.9 ft swell from the east. The wave energy is strong (403-665), but the wind is howling cross-shore and cross-offshore. Tuesday has a 43.5 mph cross-offshore gale that cleans the surface, but the swell period is only 8 seconds, and it’s a brutal paddle. This is for the kamikaze crew only.

Wednesday, September 9th, is a total write-off. The swell drops to 3.3 ft to 3.6 ft, with a pathetic 5-second period and combined energy of just 45 to 58. The wind is strong offshore, but the swell is so weak and short-period it’s nearly flat and impossible to ride.

Finally, we get one more glimmer. Thursday, September 10th, looks promising. It’s ten days out, so take it with a grain of salt, but the forecast shows a 3.3 ft swell from the east with a 10-second period, light 6.2 mph cross-offshore wind from the north, and clean conditions. The combined energy is moderate at 287. This could offer a few fun, clean waves, but it’s a one-morning
