The Lowdown
Alright, this is Rusty. Let's be real about what we've got coming up for Kodogawa. It's a beach-and-sandbar setup, and it's a bit of a tease. The water's sitting at about 81°F, which is a touch cooler than average for this time of year, but nothing to shake a stick at.
First up, we've got a dry spell of no surf worth mentioning. From Wednesday the 22nd all the way through to Friday the 31st of July, it's pretty much a bust. We're talking tiny, weak waves, with the combined energy struggling to get past 150 (weak energy). The swell is all over the place, but mostly tiny and short-period. There are a few glassy mornings, but the waves are just too small and gutless to bother with. Even the 26th and 27th of July, which have a bit more energy (around 150), are still called "very ordinary." Don't bother.
Now, hold onto your board, because things change drastically. The first real sign of life arrives on Saturday, the 1st of August. The morning session is looking promising with clean, glassy conditions and a pulse of ESE swell at 3ft, with a long period of 16 seconds. The energy jumps to 502 (moderate). That's a proper groundswell. The wind is dead calm, so it'll be clean. But this is just the warm-up.
The standout period, without a doubt, is Sunday the 2nd through Tuesday the 4th of August. We're looking at a solid run of ESE groundswell. Sunday morning kicks off with 5ft swell at 18 seconds (very long period) and a massive energy reading of 1472 (strong). It's glassy, it's clean, and this is the best on offer. Monday the 3rd steps it up even more, with 6ft swell at 18 seconds and energy hitting 2359 (very strong). That's some serious juice, but at 6ft, it's getting into expert territory. The morning is glassy again, so if you can handle it, it's going to be epic. Tuesday the 4th still has a great 6ft swell with energy at 1827 (strong), and the morning is clean.
The caveat with this long-period swell (18 seconds) is that it's going to be a bit straightened out by the beach break. It'll be better if you can find a corner or a sandbar that lines up with it. But for power and shape, this is the best window we've got.
After that, Wednesday the 5th and Thursday the 6th of August start to wind down, dropping to 4ft and 3ft. The afternoons get cross-onshore, so make the most of those mornings.
So, to sum it up: the first week and a half is a total write-off. The second week, specifically the mornings of August 1st through 4th, are your only real chance at some quality. The standout is Monday the 3rd of August, with that 6ft, 18-second groundswell and glassy conditions—that's the one to circle on the calendar.
Rusty.

Information about the Kodogawa Surf forecast
The above surf forecast table for Kodogawa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kodogawa can be found by selecting the local surf guide option on the grey menu. Our Kodogawa 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 (Kodogawa) 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 Kodogawa 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.
Kodogawa is 16 km (10 miles) from Nobeoka. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Nobeoka. Nobeoka has rooms for a wide range of budgets as well as car hire and transport links.
