Alright, crew, Rusty here. Let’s talk about what’s cooking for Udo Shrine over the next couple of weeks.

Right off the bat, we’ve got a bit of a slow start. Monday morning is small – just 0.4m from the ESE, with a very long 18-second period. The water temp is running a bit colder than normal for this time of year, coming in at 26°. It’s surfable but nothing to write home about. The afternoon stays small, but the conditions look better with offshore wind, so the quality improves.

Now, Tuesday 7 July is where it starts to get interesting. The morning is the real standout early in the period. We’ve got a clean 1.4m swell from the SE, 14-second period, and the wind is glassy – absolute perfection for a reef break like this. The combined swell energy is moderate at 685. This is the session to aim for if you want smooth, well-shaped waves without the hassle of wind. Crowds are common here, but on a morning like this with that quality, you’ll be sharing it with some happy locals.

Tuesday afternoon gets a bit trickier. The swell jumps to 1.6m from the SE, but the wind swings cross-onshore and there’s a risk of thunderstorms. The wave energy climbs into strong territory at 1192, but the conditions are marginal. Still surfable if you’re keen, but the morning is where it’s at.

From Wednesday 8 July through to the weekend, the story changes. Swell sizes start climbing fast – 2.5m on Wednesday morning, 3.0m in the afternoon, then 3.5m on Thursday, 4.0m on Friday. The direction shifts from SE to SSE and later S, and the periods stay solid between 16 and 18 seconds. This is proper groundswell. But here’s the catch – the wind is onshore or cross-onshore for almost all of this run, with moderate breezes and stormy conditions likely. The wave energy is huge, topping out at 12,382 on Friday afternoon (very strong energy), but it’s going to be big, messy, and blown out.

This kind of size – over 2.5m – is for experienced surfers only, and honestly, with the wind on it, it’s not going to be pretty. If the wind had cooperated, this would have been epic, but as it stands, it’s more of a spectacle than a go-out.

Saturday 11 July and Sunday 12 July are still big – 3.5m dropping to 2.1m – but the wind stays tricky. Saturday has cross-onshore chop, Sunday is onshore with period dropping to 12 seconds. The quality just isn’t there.

Now, we get a bit of a breather early the following week (13 July), with smaller swell around 1.6m to 1.8m, but the wind is cross-shore or cross-onshore. Nothing special.

But hang on – Tuesday 14 July morning is another genuine standout. The swell jumps back up to 3.5m from the ESE, period around 10 seconds, and the wind goes glassy again. Combined energy is 4682 – strong wave energy. This is excellent surf for experienced surfers. Glassy conditions on a reef with that kind of size? That’s a proper session. The swell direction from the ESE is a good match for the optimum S direction, and with no wind, it’s as clean as it gets. Later that afternoon it gets bigger at 4.5m but the wind swings cross-shore and messes it up.

Wednesday 15 July morning has a smaller 2.1m ESE swell with glassy winds again – very good conditions, though only moderate energy (888). Thursday 16 July morning stays clean with cross-offshore wind, 2.1m from the E, and Friday 17 July is smaller but clean in the morning.

Then we roll into Saturday 18 July and Sunday 19 July. Saturday morning is glassy with 1.9m from the E – very good. Sunday morning is absolutely still – zero wind – and 2.2m from the E. That’s a dreamy morning for the reef. Combined energy is moderate at 781 and 838 respectively. Keep an eye on those.

After that, Monday 20 July is still decent size at 2.3m from the E, but the wind gets tricky, and by Tuesday 21 July we’ve got strong cross-onshore winds (35-40 km/h) and the wave quality drops hard – poor conditions and nothing worth chasing.

So, if you want the absolute best windows, focus on Tuesday 7 July morning for a clean, smaller session, and Tuesday 14 July morning for bigger, glassy power. Sunday 19 July morning is also a beauty if you’re around.

Rusty out.

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.
