The Lowdown

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.

Rusty.

Information about the Udo Shrine Surf forecast

The above surf forecast table for Udo Shrine provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Udo Shrine can be found by selecting the local surf guide option on the grey menu. Our Udo Shrine surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Udo Shrine) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Udo Shrine may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
