The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for Uchiumi over the next couple of weeks.

Honestly, it's a pretty quiet start. We're looking at several days of tiny, weak waves with no real energy behind them. The first half of the outlook is a bit of a flat spell, but don't lose hope—there's a proper pulse of swell trying to build in the second week, though it comes with some serious size.

The first real chance to get wet comes up on the morning of the 28th of July. The swell is still small, only around 2ft from the ESE, but the wind goes glassy, making it ridable. The energy is weak (95), so you'll be fighting for every bit of push, but it's clean. That same glassy, clean theme pops up again on the morning of the 29th, with the same small surf, but it's still small.

We've got a long stretch of small, unremarkable surf until things start to change. The morning of the 3rd of August is the first real turning point. The swell picks up to 3ft from the ESE, with a nice 12-second period, and the wind is glassy. The energy jumps to a moderate 320, and it's finally looking like a proper session. That morning is likely the best of the early window.

The real standout, though, is the 5th of August. Wednesday morning we see a solid 12ft swell from the east, with a long 18-second period. The energy is massive (8366), and the wind is light cross-onshore. This is big, powerful, groundswell. The same hits again on Wednesday afternoon with 13ft at 19 seconds, and energy over 10,000. This is not a beginner wave. With that size and long period, it's going to be a proper, heavy, expert-only affair. The 6th of August looks even bigger, with 18ft swell, but it's flagged as too big for the break. If you're a seasoned charger, the 5th is your window.

After that big pulse, the swell drops back quickly. The 7th of August sees it drop to 4ft, and the 8th brings a bit of a bump from the SSE at 5ft, but it's nothing like the earlier days.

So, looking at the whole stretch, the morning of the 3rd of August is the pick for a clean, fun, medium-sized session. But if you're looking for raw power and size, the 5th of August is the one to circle on the calendar, though it's for the experienced crew only.

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.
