Udo Shrine Surf Forecast and Surf Report

Alright, Rusty here. Let’s get into it.

First off, it’s a pretty quiet start for the next few days. The swell is small and the wind is just not doing us any favours. We’ve got a bit of a wait on our hands.

Looking at Udo Shrine (Japan), the first glimmer of hope shows up on the morning of Sunday, August 2nd. The forecast is calling for a clean, glassy morning with a small 2ft swell from the ESE. The period is a very long 16 seconds, which is proper groundswell, and the combined energy is moderate at 260. This is a reef break that’s inconsistent, so it doesn’t break often, but when it does, that long period could set up some nice lines. Keep in mind crowds are often a factor here. The water temp is about average for this time of year.

Sunday afternoon gets a bit more size at 3ft, but the wind goes cross-shore and the conditions become marginal. Monday the 3rd gets bigger, with 5ft to 6ft swell from the ESE, but a strong cross-onshore wind makes it choppy and messy. The combined energy jumps to strong levels (1356 to 2025), but the wind is the enemy.

From Tuesday the 4th onwards, the swell just keeps building, but it gets ugly. By Wednesday the 5th, we’re looking at 16ft to 20ft waves with a monstrous 18-19 second period and energy readings over 14,000 — that’s very strong. But the wind is howling onshore at 25 mph, turning it into a complete mess. The forecast notes straight up say the swell is too big for this break. This is more of a kite surfing situation than paddle surfing.

The big stuff keeps rolling through the 6th, 7th, and 8th, with waves up to 31ft and energy over 100,000, but it’s accompanied by near-gale force onshore winds. Absolutely not for the faint of heart, and not for a clean surf.

Things start to settle down a bit from the 9th, but the onshore wind persists, keeping conditions poor through the 10th and 11th. We get a few marginal windows on the 13th and 14th, with 4ft to 5ft ESE swell, but the wind is still cross-onshore, so the quality is low.

The standout session is undeniably the morning of Sunday, August 2nd. That’s your best bet. It’s the only time we get glassy conditions and a clean, rideable wave. The swell is small, but that long period will give it some punch for a reef. It’s inconsistent, but when it’s on, it’ll be worth it.

Other than that, this 16-day window is mostly a write-off for Udo Shrine. The first few days are flat, we get one good clean morning, then it’s either too small, too windy, or dangerously big. A tough stretch.
