Tengan Surf Forecast and Surf Report

Alright folks, it’s Rusty here. Let’s be straight with you—this stretch at Tengan is looking pretty grim for a while. The first couple of weeks are mostly a write-off, but there’s a glimmer of hope right at the end of the 16-day window.

Right now, and for the next several days, the swell is tiny and the energy is weak. We’re looking at ankle-to-knee-high waves from the north, with combined energy readings barely hitting 28 on Thursday morning. It’s glassy, which is nice, but there’s just nothing to ride. This flat spell stretches on with no real surf to speak of through the 13th, 14th, 15th, and 16th of August. The swell stays small, and the wind, while light, doesn’t help.

By the 17th and 18th, the wind swings onshore and the swell gets a little bump, but it’s short-period, messy, and still poor. The 20th of August sees a bigger bump in swell—around 5 ft to 6 ft from the ESE (345 to 584 combined energy)—but it’s blowing a fresh 22 mph cross-onshore wind, making it lumpy and unrideable. That one’s more for the kite crew than paddlers.

The real standout comes at the very end of the forecast. On Tuesday, the 25th of August, we finally see something worth waking up for. The morning starts calm with glassy conditions and a 2 ft east swell at a long 12-second period (208 energy). It’s small but clean. The afternoon is the pick of the whole run: 3 ft east swell, 15-second period, combined energy of 374, and glassy, offshore wind. That’s a beautiful window of clean, long-period groundswell. Tengan is a reef break, so this long-period energy will wrap in nicely, offering some proper shape. The water temp is sitting at 84°, which is about average for this time of year.

Then Wednesday the 26th holds some small, clean waves but with a light cross-onshore wind—still rideable for the patient. Thursday the 27th and Friday the 28th of August bring offshore winds and chest-high waves from the east and ENE, with periods holding around 13-14 seconds and energy jumping back up to 350-429. That Friday afternoon is looking real sweet: 3 ft, glassy, clean.

So, if you’re holding out, the last few days of August are your best bet. The 25th afternoon and the 28th are the two true standouts—clean, glassy, proper groundswell. Just don’t expect much before then.

Rusty.
