The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next stretch.

First up, we’re lookin’ at Kodogawa, a beach and sandbar set-up that’s a bit sheltered and inconsistent. The water temp is sittin’ at 82°, which is bang on average for the time of year, so no surprises there.

The forecast kicks off with a long, slow grind. From Tuesday the 8th through to the tail end of the following week, the surf is pretty ordinary. There’s a bit of wave energy around, with combined swell energy reading 301 (moderate) on Tuesday morning, but the conditions are just average. The 4ft of east swell, at a short 8-second period, is not gonna get the heart pumpin’. The wind is cross-offshore, which keeps it clean, but it’s just not got that spark. Wednesday the 9th through Friday the 11th stays in that same zone – small, short-period swell, and mostly cross-off breezes, but nothing to write home about.

Saturday the 12th and Sunday the 13th see the swell drop right off, with heights barely 1ft to 2ft. The period jumps to 14 seconds on Saturday morning, which is a long-period groundswell, but it’s so small it’s barely a ripple. Saturday morning is clean, and Sunday morning is glassy, which is a treat, but with no wave size, you’re just floatin’ around.

We hit a few more days of small, inconsistent surf through the start of the next week, with combined energy between 100 and 300. The wind stays light and mostly cross-off or glassy, so it’s clean, but the energy is just not there.

Now, here’s where it gets a bit interesting. The standout is the pair of days on Monday the 21st of September and Tuesday the 22nd of September. The swell finally puts in an appearance. On Monday morning, we’ve got 8ft of east-southeast swell, with a very long period of 16 seconds. The combined energy is a massive 4264 (very strong). This is a proper groundswell. The wind is cross-off from the north-northwest, so it’s gonna be clean. This is big, powerful, long-period swell – it’s not for the faint-hearted. Over 8ft, this is expert-only territory. The long period will make it break straight at a beach break, but with that size and direction, the sandbar might line up some wedges. Tuesday is similar, 8ft, still 15-second period, and clean. This is the best on offer, no question.

The first week of the forecast is a write-off for quality surf. There’s a big gap of nothin’ decent until that big pulse arrives around the 21st. After that, Wednesday the 23rd still has some clean, smaller waves at 4ft, but it’s a step down.

So, the honest truth is: wait for that big groundswell around the 21st and 22nd. It’s a long way out, but it’s the only real shot at something memorable. Keep an eye on it, but don’t bet the farm yet.

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.
