Alright folks, Rusty here. Let's see what's cooking for us at Udo Shrine. We've got a wild ride ahead over the next couple of weeks, with a serious pulse of energy rolling in, but we'll need to pick our moments carefully.
There's a decent gap of a few days with absolutely nothing worth paddling out for right at the start, but the waiting is going to pay off. The first real window to wet a line is Tuesday afternoon the 7th of July. The water is sitting at 79°, which is a bit colder than normal for this time of year – a noticeable nip in the air and water.
The standout session, without a doubt, lands on Friday the 10th of July. That morning we've got a solid 13ft swell out of the SSE, with a long period of 16 seconds, packing serious power. This is proper groundswell, and for a reef break like Udo, that's a beautiful thing. The wind is a light ENE breeze, blowing straight onshore, which keeps it a bit lumpy but still surfable for the experienced crew. The afternoon sees it crank up even more to 15ft, same direction, and that's getting into big-wave territory. This is expert-only stuff here; if you're not comfortable in heavy water, sit this one out.
Saturday the 11th holds that size through the morning, 13ft from the south, still that long 17-second period. It’s carrying massive energy, but the wind picks up to a moderate breeze, making it a bit more challenging. The afternoon session gets a score of zero for surf conditions as the wind really kicks in, so aim for the early bird paddle.
By Sunday the 12th, the swell eases back to 8ft, but the wind turns cross-onshore, and we get a "gentle cross-onshore and fairly choppy" description. It’s not the cleanest, but there are still waves to be had. Things taper off pretty quickly after that.
Monday the 13th drops to 5ft, but the wind is cross-shore and messy. Tuesday the 14th morning sees a brief moment of glassy conditions on a small 3ft south swell, but it’s tiny and weak. A long gap of small, poor-quality, or onshore surf follows until...
Friday the 17th of July morning. This is a sneaky little window. We get a clean 3ft swell from the east with a light offshore wind from the west. It’s small, but for a reef break, that offshore wind will have it looking like glass. One of those sessions where you might get a few fun little runners to yourself.
After that, it's a long, drawn-out fade into tiny, wind-affected slop for the rest of the period. The combined energy drops quite a few times, meaning it's just not worth the effort.
In short: set your alarm for Friday the 10th of July for the big, powerful south groundswell, and keep an eye on Friday the 17th for a clean little offshore session. The rest is a waiting game.
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.
Udo Shrine is 10 km (6 miles) from Nichinan. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Nichinan. Nichinan has rooms for a wide range of budgets as well as car hire and transport links.
