Udo Shrine Surf Forecast and Surf Report

Alright, this is Rusty checking in. Let's have a look at what's on the menu for the Udo Shrine (Japan) region over the next couple of weeks.

Right off the bat, it's a bit of a slow start. We're looking at Tuesday the 8th and it's a write-off – fresh cross-onshore winds and a lumpy mess. Not worth paddling out for. The surf is building a little through the day, but it's just ugly.

The first real glimmer of hope comes Wednesday the 9th. The morning is showing glassy conditions with a light WSW wind, and the swell is a clean 4ft from the ESE. The combined energy is moderate at 254, but the key here is that glassy surface. It's going to be clean. The afternoon stays glassy too, with a little risk of a thunderstorm. For a reef break that's inconsistent, a glassy day like this is a real treat. It's a window of opportunity, even if the swell isn't massive.

The rest of that week and into the weekend is a bit of a letdown. Thursday and Friday are plagued by cross-onshore winds, dropping swell, and just plain choppy conditions. The energy drops off, and it's not going to be fun. Saturday the 12th is glassy in the morning, but the swell is tiny at 2ft – barely a ripple. Sunday the 13th is back to the cross-on wind and chop.

We get a bit of a pulse of energy on Monday the 14th, with the combined energy jumping to over 400 (moderate), but it's blown out by a strong onshore wind. No good. Tuesday the 15th sees some size at 6ft, and the wind eases, but it's still cross-on, leaving it a bit bumpy. The swell period is 10 seconds, so it's a mix of wind and ground swell.

Now, here's where it gets interesting, but you've got to look ahead. The real standout is way out there, on Monday the 21st of September. A very long-period groundswell (16 seconds) from the ESE is forecast to roll in, pushing 7ft in the morning and 8ft in the afternoon. The combined energy is massive – 2449 in the morning and 2676 in the afternoon – that's strong wave energy. Now, this is a reef break, and that long-period swell will be a beauty here, offering up some proper, powerful lines. The wind is light, so it should be clean. Be aware, this is a long-range call, so it's a promising one, but not set in stone. For the experts, Tuesday the 22nd gets even bigger, with 8ft to 10ft swell and energy over 3500, but it's got a bit more wind on it, so expect some chop. That kind of size is for experienced surfers only.

So, the best on offer? Without a doubt, the glassy window on Wednesday the 9th for a clean, small session, and the big potential of the Monday the 21st for those who can wait for a proper groundswell. The 21st is the one to circle on the calendar.
