Alright, folks, Rusty here. Let's take a look at what's cookin' for Uchiumi over the next couple of weeks. It’s a bit of a slow burner, but there’s a big finish on the horizon.

Right out of the gate, we’ve got a bit of a flat spell. The first few days, from Friday the 3rd to Monday the 6th of July, are a write-off. The waves are tiny, around 2 ft to 2 ft, and the conditions are a mixed bag. There’s some glassy moments early on, but the energy is weak – we're talking combined swell energy in the 40s and 50s – so it’s really not worth paddling out for.

Things start to get interesting on Tuesday the 7th. The water temp is sitting at 77°F, which is a bit colder than normal for this time of year, so you might want a light spring suit. Tuesday morning looks like the first real chance. The wind drops to glassy, and we get a nice little 4 ft ESE groundswell with a period of 15 seconds – that’s some proper long-period energy. The combined energy jumps to 897. It won’t be huge, but it should be clean and fun for an intermediate on a reef like Uchiumi. The afternoon gets bigger, 6 ft, but the cross-onshore wind kicks in and makes things pretty ordinary.

Wednesday the 8th sees the swell really start to build, hitting 10 ft from the SE with a period of 18 seconds. That’s a powerful, very long-period groundswell (combined energy over 5400). But here’s the thing – that’s getting big for this spot, pushing into expert-only territory. The wind is onshore and sideshore, so it’s going to be a choppy, challenging mess unless you’re really experienced and know where to sit. This big energy sticks around through Thursday the 9th and Friday the 10th, with the swell peaking at 13 ft on Friday afternoon. The winds remain tricky, so even though the numbers are massive (combined energy over 8400 on Friday), the quality isn't there for a relaxed session. If the wind cleans up, this could be incredible, but as it stands, it's a watch-and-see situation for the pros.

We finally get a bit of a window on Sunday the 12th. The swell drops to a more manageable 6 ft from the SSE, the period is a solid 12 seconds, and we get a clean cross-offshore breeze. The combined energy is still a moderate 951. That’s probably the most user-friendly day of the first week for an intermediate surfer looking for clean, lined-up reef waves. After that, the swell slowly fades through the middle of the week, with clean but small conditions returning.

Now, the real standout. Mark your calendars for Thursday the 17th of July. Friday the 17th, honestly. Friday morning is shaping up to be absolutely nuts. The forecast shows 13 ft of SE swell, a period of 16 seconds, and glassy conditions. The combined energy is through the roof at 7964. That is a world-class, groundswell wall heading straight for Uchiumi. It’s for experts only at that size, but if you can handle it, those waves will be perfect. The afternoon, however, might be too much of a good thing, with the swell jumping to a colossal 20 ft. At that point, it’s likely just unsurfable closeouts. So, the early morning of the 17th is your golden ticket – a true, but long-range, standout for the big dog surfers.

Saturday the 18th drops off quickly with a shorter period windswell, so that big window slams shut fast.

So, to wrap it up: the start is a bust, we get a few okay windows in the middle of the first week, but the real, epic, no-doubt-about-it session to keep an eye on is the morning of Friday the 17th of July. It's a promise from the charts, but it's two weeks out, so we’ll have to keep our fingers crossed it holds.

Stay stoked,
Rusty

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.
