The Lowdown
Right then, grab a cuppa, let’s have a look at what’s coming up for Kodogawa.
Honestly, for the first few days, it’s a bit of a write-off. We’re looking at flat, tiny slop until the end of the month and into the start of August. The water temp is about average for the time of year, nothing to write home about. From Tuesday the 28th of July right through to Saturday the 1st of August, the swell is barely a ripple – 1 foot to 2 feet at best, with weak energy readings (75 or less). The winds are light and glassy in the mornings, which is nice, but there’s just nothing to push you around. It’s a frustrating stretch of flatness.
Then we get a tiny pulse on Sunday the 2nd of August. The morning shows a 1 foot swell from the ESE with a long 16-second period, and the combined energy jumps to 117 (weak). Early glassy conditions might make it surfable for a log, but it’s very ordinary. The afternoon turns poor again.
Monday the 3rd of August sees a real jump. The morning swell is 4 feet from the ESE, with a period of 14 seconds and a moderate energy reading of 661. The wind is a light cross-onshore, which is a bit messy. The afternoon gets bigger, 5 feet from the ESE, but the period stretches to 16 seconds and the energy jumps to 1087. Still, it’s cross-onshore, so it’s not clean.
Now, Tuesday the 4th of August is where it gets serious, but it’s not for everyone. The morning brings a 8 foot ESE swell with a massive 18-second period and a strong energy reading of 3299. The wind is light cross-shore. This is too big for beginners, and that long period groundswell will be breaking a bit straight on the beach, so it’s a tricky one. The afternoon is 8 feet and cross-onshore, which is even messier.
The standout window is Wednesday the 5th of August. Early morning, the stars align. We’ve got a 10 foot ESE swell, an 18-19 second period, and a very strong energy reading of 7298. The wind is glassy from the NNW. This is the best of the lot – clean, powerful, and organised. It’s a big day for experienced surfers only. The afternoon gets cross-onshore and messy again.
Thursday the 6th of August is a total washout for paddle surfing. The swell is 20 feet to 23 feet with a 19-second period and energy readings through the roof (24,235 and 32,634). The wind is a strong offshore, but the swell is simply too big. For a beach setup, this is more of a kite surfing zone than a paddle board.
The 7th and 8th of August are blown out or too big. The swell peaks at 44 feet with severe gale force winds.
After that, the swell drops back. Sunday the 9th of August morning is interesting: a 7 foot S swell with a short 8-second period, but glassy conditions and a moderate energy reading of 937. It’s surfable, but the short period means it’ll be a bit fat and disorganised. The rest of the second week (10th to 12th of August) looks like a return to weaker, wind-affected conditions with poor surf.
So, to put it simply: the first week is a dud until the 3rd, and the 5th of August is the only real standout for experienced crew. The big stuff on the 6th and 7th is a no-go for paddle surfing.

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.
