Udo Shrine Surf Forecast and Surf Report

Alright, this is Rusty, and I’ve got the goods on the Udo Shrine (Japan) region for the next couple of weeks. Let’s cut the chit-chat and get to it.

Right off the bat, for the next week, we are looking at a real stretch of poor conditions. We’ve got days of onshore winds, thunderstorms, and messy cross-chop that are just not worth paddling out for. The energy is weak to moderate through this period. The water temp here is sitting at 83°F, totally normal for the time of year, so that’s one thing we don’t have to worry about.

Friday the 21st sees a little spike in energy (combined swell energy of 533), but it’s coming with moderate rain and a cross-shore wind. The swell is 5ft from the south at a 10-second period, but it’s still only marginal surf. Not the standout by a long shot.

Now, hold onto your leash, because this is where it gets interesting. Monday the 24th is the beginning of something special. The morning brings clean conditions with a light offshore breeze. The swell is only 3ft, but check this: it’s coming from the ESE with a monster 18-second period (combined energy of 1097). This is a long-period groundswell. Udo Shrine is a reef break, so this long-period energy is going to wrap in beautifully, offering clean, lined-up waves. This is the best first call.

Then, the absolute standout, the one you clear your calendar for, is Tuesday the 25th. Get this: 13ft of southeast swell, 16-second period, with glassy conditions in the morning. The combined energy hits 7163. We are talking exceptional, expert-level surf. This is big, powerful, and clean. This is not for beginners – at over 8ft, it’s expert territory only. The wind goes a little cross later, but the morning window is pure magic.

Wednesday the 26th keeps the swell pumping, with 16ft in the morning, but the wind turns cross-onshore. Still a big day for experienced surfers, just not as pristine as Tuesday. After that, the wheels come off again. From Thursday the 27th through to the end of the month, we are back to strong onshore winds and stormy conditions. The swell stays huge (over 12ft), but with onshore winds howling from the NNE, it’s going to be a blown-out mess. The combined energy is massive, topping out at 12976 on Saturday the 29th, but with 19 mph onshore winds, this is a kite-surfing show, not a paddle-surf one. There is a glimmer on Monday the 1st of September, with a 10ft ESE swell and a 17-second period, but the wind is still onshore and the rating is marginal.

So, to sum it up: suffer through the first week. Monday the 24th is your starter. Tuesday the 25th is the absolute standout – a glassy, 13ft groundswell at a reef break. After that, it’s a week of wind and washing machines.
