The Lowdown

G’day, Rusty here. Look, I’ve gotta be straight with you – the next couple of weeks at Udo Shrine (Japan) are a mixed bag, and honestly, there’s a lot of waiting involved. The water temp is sitting about average for this time of year, nothing to write home about.

The week kicks off with a real dud. Wednesday the 26th is a write-off – we’ve got a solid 10ft SSE swell rolling in, but it’s getting hammered by a cross-on ESE breeze at 16 mph, making it choppy and messy. The combined energy is strong at 3286, but it’s a waste. Afternoon drops to 6ft, still cross-shore and lumpy. Thursday the 27th is a little better – morning is still cross-shore and messy with 7ft, but the afternoon cleans up nicely with a cross-offshore S wind at 12 mph. That’s your first real window: 7ft from the SSE at 8 seconds, but the period is short, so it’s a bit weak.

Friday the 28th morning is the standout of the first week. The swell drops to 4ft from the SSE, but the wind is a light cross-offshore breeze from the south at 6 mph, and it’s clean. The energy is weak at 351, but it’s surfable. Afternoon flattens out to 2ft from the east with a long 13-second period, but it’s pretty weak. Saturday the 29th morning is tiny at 2ft from the east, 12-second period, clean and light, but you’ll be fighting for scraps. Sunday the 30th morning is glassy – 2ft from the east, 12-second period, and the wind is dead calm. It’s tiny, but if you’re desperate, it’s there.

Monday the 31st through Tuesday the 1st of September gets ugly. Onshore winds blow everything out. Tuesday the 1st has a big 10ft SE swell with a 14-second period, but it’s onshore at 22 mph – dangerous and messy. Wednesday the 2nd is even worse, with 12ft and a near-gale cross-on shore. Don’t bother.

Then, on Thursday the 3rd of September, we get a serious pulse. The swell jumps to 16ft from the SE at 11 seconds, with a clean cross-offshore SSW wind at 12 mph in the morning. The combined energy is pumping at 6411 – that’s strong. This is the best on offer, but it’s massive. Over 8ft means it’s for experts only. The afternoon holds at 15ft with a lighter W wind, also clean. This is a true standout, but it’s a week away and the long-range forecast has some uncertainty. Friday the 4th sees 15ft dropping to 12ft, but the wind shifts cross-onshore, so it’s less clean. By Saturday the 5th, it’s back to onshore junk.

The second week from the 5th onward is mostly onshore slop, with a few pulses of size but poor wind. That 16ft day on the 3rd is your best bet, but bring your big-wave board and don’t expect any company – it’s too big for most.

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.
