Table - best surf conditions forecast for Kodogawa over the next 16 days.
Alright, let’s break down Kodogawa (beach/sandbar) for you.
First thing – this spot is going to be a bit of a slow burn. Most of the first week and a half is pretty ordinary, but there’s a real bright spot at the end of July.
Friday the 10th of July starts with a solid 12ft SSE swell, long period of 16 seconds, and the wave energy is pumping at 6300. But the wind is cross-onshore, conditions are messy, and there’s thunderstorms around. That swell is too big for beginners, and with that period, it’ll be closing out hard on the sandbar.
Saturday the 11th is much the same – still 12ft and 17-second period in the morning, but by afternoon the wind goes onshore and the quality drops. Not a day to get excited about.
Sunday the 12th of July – things shift. The swell drops to 7ft from the SSE, period down to 13 seconds, and the wind goes glassy in the morning. Wave energy is moderate at 1334. That’s your first real chance: clean, glassy, but still a solid wave – better for confident intermediates. The afternoon turns onshore again.
Monday the 13th morning sees the swell back to 4ft, glassy, 11-second period (445 energy). Clean but small, and with this spot being inconsistent, you’ll be waiting for sets.
From Tuesday the 14th through to Wednesday the 22nd of July, it’s mostly tiny, weak, and messy. Swells drop below 3ft, periods are short, and energy numbers are in the low double digits or hundreds. A few glassy mornings but honestly, not worth the paddle. There’s a long stretch of days with nothing decent.
Then Thursday the 24th of July morning – this is the one. Swell bumps to 5ft from the SSE, 12-second period, with wave energy at 729. Wind is glassy. That’s the standout session of the whole outlook. Clean, proper groundswell, good shape if the tide plays nice. The afternoon still has 5ft but the wind goes onshore, so the morning is the peak.
Saturday the 25th of July morning keeps it going: 4ft SSE, 10-second period, glassy, with 513 energy. Still a decent little option, but not as punchy as the 24th.
Bottom line: circle Thursday the 24th of July morning – glassy, 5ft SSE groundswell, clean. That’s your best bet. The rest of the month is either too big and blown out, or too small to bother.

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.
