The Lowdown
Alright, this is Rusty. Let's get straight into it. Looking at the whole 16-day window, I got to be honest with you, it's a rough one for Udo Shrine (Miyazaki). The first week or so is completely blown out by strong winds, and the second week drops off into tiny, messy stuff. There's no real standout session here, but there's a couple of moments that might be worth a look if you're desperate.
The first bit of surf we can talk about is Monday the 3rd of August. We're looking at 5ft of swell from the ESE, but it's coming with a 16-second period, which is a proper long-period groundswell. That's the good news. The bad news is the wind is cross-on from the NNE at 12 mph, making it choppy. The combined wave energy is moderate at 1346, but the conditions are just marginal. By the afternoon, it's onshore and a write-off.
Tuesday the 4th sees the swell jump up to 8ft, still from the ESE with a very long 17-second period. That's a lot of energy pushing in (3092), but with the wind still howling onshore at 12-16 mph and thunderstorms around, it's going to be a messy, blown-out mess. This is really only for the hardcore with a death wish and a board they don't mind dinging up.
Wednesday the 5th is where it gets silly. The swell is pumping – 16ft to 18ft from the E and ESE. The combined energy is massive (14158 and 19922). The model says the wind and tide are favorable, but the swell is predicted to be too big for this break. We're talking near gale-force cross-onshore winds at 22 mph. Unless you're a tow-in expert, this is a total pass. The whole week from the 5th through the 9th is just brutal – huge swell, storms, and gale-force winds. It's more of a kite-surfing setup if anything.
After the 9th, the swell starts to drop, but the wind stays bad. The combined energy drops from over 12,000 down to a few thousand, but it's still cross-onshore and messy. By the 13th of August, we see a slight reprieve. The swell drops to 5ft from the S with a 11-second period, and the wind finally lightens up to a light breeze at 6 mph. The wave energy is weak (494), and it's still cross-onshore, but it's the closest we get to a clean wave all period. It's still a marginal call.
From the 14th onwards, it's all downhill. The swell drops below 3ft, the wind picks back up, and we're looking at tiny, choppy, blown-out junk for the rest of the window. The last few days are just poor.
So, if you're set on paddling out, keep an eye on the 13th of August. It's the only day with light wind and a hint of swell. But honestly, for this 16-day stretch, the forecast is bleak. It's a classic case of "maybe next week." The water temps are about average for the time of year, so no excuses there.

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.
