Table - best surf conditions forecast for Kodogawa over the next 16 days.
Alright folks, Rusty here. Let’s get straight into it. The outlook for Kodogawa is a real mixed bag over the next 16 days, and it’s one of those stretches where you’ve gotta be patient and pick your moments. The swell is mostly small and inconsistent, with a brief window of cleaner, more energetic waves early on.
The standout of the whole period is hands down Monday morning, July 13th. We’ve got some solid SSE groundswell rolling in at 4ft with a nice long 11-second period, pushing a decent amount of energy (438). The wind is glassy from the south at just 3 mph, so it’s going to be clean and lined up. This is your best bet for a proper surf. The water temp is about average for the time of year, nothing wild. Just keep in mind that Kodogawa is a beach/sandbar setup that’s inconsistent and can get crowded often, so be prepared to share the peaks.
After that, Tuesday morning, July 14th, is still worth a look. It’s smaller, dropping to 3ft from the south, but it’s glassy calm with zero wind. The energy is moderate (154). It’s a low-key session for a longboard or a fun board, but don’t expect anything firing.
From Wednesday, July 15th, right through to the end of the first week, the surf really drops off. We’re looking at tiny waves, mostly under 2ft, with weak energy (down to 41-70). The wind is light, but the swell just isn’t there. It’s a solid gap of poor conditions.
There’s a little spike around Saturday morning, July 18th, with a 4ft ESE swell and a 12-second period, pushing moderate energy (432). But the wind is cross-shore, making it messier, and the score is marginal. It’s a maybe, but not a standout.
The second week is a waiting game. From July 20th into the 23rd, there are a few mornings with glassy conditions and 3ft to 5ft ESE swell, but the energy is only moderate and the consistency is poor. The mornings are the only chance, and the afternoons get blown out. It’s surfable, but ordinary.
After July 24th, it goes flat again. The swell drops below 2ft, energy is weak, and the wind is often cross or onshore. The last few days of the month are a write-off.
So, to sum it up: Monday morning, July 13th is the clear winner. Glassy, decent chest-high swell, and a bit of push. Tuesday morning, July 14th is your backup. Everything else is for the die-hards or the kite crew, because honestly, with the wind and small swell, it’s looking more interesting for kiting than paddle surfing.
Stay patient, and keep an eye on the forecasts.

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.
