Table - best surf conditions forecast for Kodogawa over the next 16 days.
The Lowdown
Alright, this is Rusty. Let’s break down what’s on the table.
We start off slow at Kodogawa on Monday morning with a calm, glassy 3ft wave from the ESE, period around 9 seconds. Water temp is 81°, about normal for the season. The energy is weak (213), so it’s small and nothing special. The break is inconsistent, so you’ll be doing more sitting than riding.
Tuesday morning improves a touch – 4ft, still glassy, from the same direction, with a 10-second period. Energy bumps to moderate (398). It’s clean and surfable for intermediates, though the beach can get crowded when conditions are half-decent.
Wednesday through Friday are messy with onshore winds and poor conditions. The swell tries to build but it’s all blown out and choppy. Not worth getting wet.
Then we hit the good stuff. Saturday the 19th of September through Monday the 21st, Kodogawa sees a major pulse. Saturday morning is the pick: 8ft of long-period groundswell from the ESE, 16-second period, clean cross-offshore wind, and massive energy (5159). This is powerful, serious surf – best left to experienced surfers. The long period gives it real punch, with long lulls between sets. Sunday and Monday are even bigger, with 13ft and 12ft respectively, still clean but huge – experts only.
After that, a gale on Tuesday the 22nd destroys the surf, and the rest of the forecast is flat with tiny, weak waves (energy mostly under 100). The last week is a write-off.
Your best window: Saturday the 19th morning. Big, clean, and powerful. Expect a crowd and bring your A-game.

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.
