Alright mate, let's chew the fat on Uchiumi for the next couple weeks.
It's looking like a rough stretch, to be honest. There's some serious size on the charts, but the wind and conditions are going to be a constant headache. The only real window of opportunity is shaping up for Friday, July 10th, and even that one's a fight.
Right from the start, Tuesday the 7th and Wednesday the 8th have some swell in the water, but it's all a bit marginal. We're talking 4ft to 8ft of groundswell from the ESE and SE with a really long period of 14 to 17 seconds. That long period brings energy, but for a reef like Uchiumi, those long lines can be a bit of a handful. The combined swell energy is climbing from a moderate 540 up to a strong 2955, but the wind is cross-on or onshore, and with storms brewing, it's not going to be clean. A hard pass.
Things get interesting on Thursday the 9th and into Friday the 10th. The swell really cranks up. Thursday morning we're looking at a solid 10ft from the SE, period of 15 seconds, and the energy is pumping at a very strong 4406. But that onshore easterly wind at 15 km/h is going to put a chop on it. Still a poor outlook.
Friday the 10th is the big dance, but you have to pick your moment. The morning offers a thumping 12ft from the SSE with a 16-second period and a massive energy reading of 7477. The wind is onshore from the east at 20 km/h, making it marginal but not a total write-off. That's a whole lot of ocean moving. This is serious, expert-only territory—over 8ft, so leave the soft tops at home. The afternoon gets even bigger, hitting 13ft from the SSE with an 18-second period (very long period groundswell) and monster energy of 9544, but the wind swings cross-on and the call is "poor surf conditions" and choppy. What a shame.
Saturday the 11th still has plenty of size, 10ft from the SSE, but that wind is still a problem, either onshore or cross-on. It's big and messy.
After that, from Sunday the 12th onward, the swell drops off a cliff. We go from 6ft down to under 3ft for a few days. The wind stays onshore or cross-on, and the conditions are labeled as "poor" for a solid week, from the 13th through the 19th of July. It’s a long, quiet stretch.
The last glimmer is on Tuesday the 22nd of July. We get a 6ft swell from the east with a short period of 9 seconds and moderate energy of 732. But the wind finally shifts offshore! It's a cross-off breeze from the SSE at 25 km/h. The wave state is described as clean. That one is a hopeful note way out there in the forecast, but it's a long way off, so take it with a grain of salt.
So, to wrap it up: the one and only true standout is Friday, July 10th. Go for the morning if you're an expert and can handle a windy 12ft of SSE groundswell with heavy energy. It's big, it's powerful, and it's going to be a battle. For everyone else, this is a waiting game until that flicker of hope on the 22nd.

Information about the Uchiumi Surf forecast
The above surf forecast table for Uchiumi provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Uchiumi can be found by selecting the local surf guide option on the grey menu. Our Uchiumi 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 (Uchiumi) 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 Uchiumi 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.
Uchiumi is 19 km (12 miles) from Miyazaki-shi. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Miyazaki-shi. Miyazaki-shi has rooms for a wide range of budgets as well as car hire and transport links.
