The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer for Uchiumi.
To be straight with you, the next week and a half is a real struggle. We’ve got a long stretch of small, weak surf and sketchy conditions. From the 15th right through to the 22nd, it’s mostly tiny waves with combined energy struggling to hit triple digits, often sitting between 47 and 175. The swell is tiny, around 1ft to 3ft from the ESE or E, with a period of 9 to 11 seconds. It’s marginal at best, and honestly, most days are getting a “poor surf conditions” tag. The wind is a nightmare too – swinging from cross to cross-onshore, and even when it goes glassy in the morning, the swell is just too weak to bother with. Saturday the 19th has a glassy morning, but the swell is still only 2ft, so it’s a session for the log or maybe a paddle.
Now, the first real glimmer of hope comes on the morning of Thursday the 23rd. The swell picks up to 3ft from the E at 11 seconds, and the combined energy jumps to 164. It’s still not huge, but with glassy conditions, it’s “surfable waves but very ordinary conditions.” That’s the best we’ve seen in over a week. Friday the 24th morning is similar, with glassy winds and 2ft, 11-second swell (energy 144).
But the real standout, the one to circle on your calendar, is the morning of Wednesday the 30th of July. This is a proper long-range promise. The swell builds to 5ft from the ESE with a very long period of 16 seconds. The combined energy is a massive 1,195. That’s a serious groundswell. Now, the caveat: it’s a long-period swell, which loves a point or a reef, and Uchiumi is a reef break, so it could set up nicely. The wind is a light cross-onshore from the NNE, which isn’t perfect, but it’s light. The afternoon of the 30th holds 6ft swell from the ESE at 15 seconds (energy 1,282), but it goes onshore from the ENE. For experts, that morning window on the 30th is the one to watch. The water temperature is sitting at 82°F, which is pretty much normal for this time of year, so no surprises there.
The 28th and 29th also show some building energy, but the wind is cross-onshore, making it a messy proposition. The 30th morning is the clear pick of the whole 16-day window.
So, to sum it up: a long, flat, frustrating run until the 23rd, then a slow build, with the real pay-off coming at the end of the month. For now, keep the board waxed and wait for that 30th.
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.
