Tengan Surf Forecast and Surf Report

Alright, let me tell you what I’m seeing for the coming days. It’s a quiet start, so don’t be in a hurry.

Right now and through the first week, Tengan is pretty much flat. We’re talking tiny 1ft SE windswell with periods around 10 seconds, and the wind is mostly onshore or cross-onshore through Sunday and Monday. Not worth paddling out for. Tuesday stays tiny, though Wednesday the 29th sees a brief window of glassy conditions, but with only 1ft on offer, it’s still not enough to get excited about. That flat spell drags on through the end of July and into the start of August, with waves barely reaching 0.7ft and mostly glassy or calm winds. Combine that with a combined swell energy that’s barely double digits (8 to 18), and you’ve got a solid week-plus of nothing doing.

But hang on—things start to stir around Monday the 3rd of August. We see a pulse of E swell building, with combined energy climbing to 164. Still too small at 1.6ft and a bit cross-onshore, but it’s a sign of life.

The real standout kicks off on Tuesday morning the 4th of August. That’s when a clean, glassy 3ft E groundswell rolls in with a 16-second period. The combined energy jumps to 406—moderate and punchy. Winds are glassy early, meaning clean, peeling waves. This is the best session of the whole window: Tengan, a reef break, loves that E swell direction, and with that long period, the waves will have real shape and power. The water temp is a warm 85°F, which is about average for this time of year.

Wednesday the 5th sees the swell push up to 4ft, but the wind swings cross-onshore, putting a bit of chop on it. Still surfable, but not as clean. By Thursday the 6th, the swell hits 4.3ft to 5ft with a 16- to 17-second period, and combined energy climbs to 1320. That’s strong wave energy. The wind remains cross-onshore, so it’ll be a bit messy but the power is there.

Friday the 7th gets bigger—6.9ft to 7.5ft E swell with 18-second intervals. That’s expert territory: too big for beginners, and with moderate cross-shore winds, it’ll be challenging but rewarding for skilled surfers. Combined energy is massive at 3388.

Saturday the 8th is the biggest day: 10ft E swell with a 19-second period and combined energy at 6348—very strong. Winds go clean cross-offshore from the WNW, so the waves will be well-shaped and hollow. That’s a big-wave reef session, only for the experienced crew.

Sunday the 9th still has solid 6.2ft to 10ft swell, but the direction swings around to ENE and NNW. The wind stays clean cross-off, so there are still waves to be had, but the size is dropping.

By Monday the 10th, a new 11.5ft NNW swell arrives, but with strong cross-onshore winds, it’s messy and not recommended for paddle surfing. That setup might be more interesting for kite surfing than a traditional surf.

So, bottom line: the first week is flat. Don’t bother. The standouts are Tuesday morning the 4th of August for clean, fun-sized waves, and Saturday the 8th of August for big, clean, expert-level groundswell.
