The Lowdown

Howdy, I'm Rusty. Let's take a look at what's cookin' on the local banks for the next couple weeks.

First off, the water's sittin' at about 83.1°, which is pretty normal for this time of year—no surprises there. The spot we're talkin' is Kodogawa, a beach-and-sandbar setup that's a bit inconsistent and sheltered from the swell. It can be a fun little wave when things line up, but it ain't the most reliable.

The forecast starts Wednesday, September 2nd, but it's a slow roll. Wednesday morning has a 4.6ft SSE swell with a 9-second period, but the wind's cross and there's a risk of thunderstorms. The energy's moderate (418), but the conditions are just marginal. Wednesday afternoon is worse—cross-on wind and poor surf. Best to wait it out.

Thursday, September 3rd, morning shows a bit of promise with a 4.9ft SE swell and cleaner cross-off wind. The energy's still moderate (423), but it's only marginal. By Thursday afternoon, the swell bumps to 5.6ft, the period goes to 10 seconds, and the wind is cross-off—clean conditions. Energy jumps to 633. It's a solid intermediate option, but nothin' special.

Friday, September 4th, is the first real highlight. The morning has a 5.2ft E swell, but the period is short at 7 seconds, so it won't have much grunt. The wind is cross-off and clean, and the energy is moderate (982). It's a good surf, but the short period means it'll be a bit messy. Friday afternoon, the swell jumps to 8.2ft from the east, but the wind swings cross-on at 18.6 mph, makin' it lumpy and poor. That's a pass.

Now, Saturday, September 5th, is where things get big but messy. The swell hits 11.5ft from the ESE with a 10-second period, but the wind is cross at 15.5 mph, and the energy is strong (2498). This is expert-only territory—too big for beginners, and the cross-chop will make it a battle. Saturday afternoon is similar, with 9.8ft and fresh cross wind. Not your day unless you're a charger.

Sunday, September 6th, is a nice clean-up. The morning has a 5.6ft E swell, cross-off wind, and clean conditions. Energy is moderate (481). It's a good, fun size for intermediates. The afternoon sees 7.2ft, still clean with cross-off wind, and energy ramps up (1363). This is a solid session.

Monday, September 7th, the morning swell drops to 5.6ft, but the wind is cross-off at 15.5 mph. It's clean, but the energy is moderate (615). The afternoon is similar with 6.2ft and fresh cross-off wind. Not the best, but surfable.

Tuesday, September 8th, brings a 9.8ft ESE swell with an 11-second period—long period groundswell. The wind is cross-off, but it's fresh at 18.6 mph. The energy is strong (1899). This is for experts only, and the long period means it'll be breakin' straight at the beach, so reefs or points would be better, but we're stuck with the sandbar. It's a beast.

The second week gets patchy. Wednesday, September 9th, is a small window: 5.9ft in the morning, droppin' to 5.2ft in the afternoon, with clean cross-off winds. The energy is moderate (706 and 523). It's ordinary but surfable. Thursday, September 10th, the swell fades to 4.6ft, and by afternoon, the wind goes cross-on, killin' it.

The real standout in the second half comes on Tuesday, September 15th. The afternoon session sees a massive 13.1ft ESE swell with a very long period of 15 seconds. The energy is enormous (6324). The wind is light and cross, so it's clean. This is a world-class swell, but it's massive—experts only. The long period means it'll be powerful and lined up, but at a beach break, it might close out. Still, if you're a big-wave surfer, this is it.

Wednesday, September 16th, morning is glassy with a 9.8ft ESE swell, 13-second period, and energy at 3457. The wind is calm, the conditions are glassy, and it's excellent for experienced surfers. This is the best of the run—clean, powerful, and well-shaped. The afternoon has a bit of cross-on wind, but it's still solid.

Thursday, September 17th, morning is glassy again with a 6.6ft E swell, 11-second period, and moderate energy (1025). It's a great session for intermediates. The afternoon picks up to 8.2ft with a 12-second period

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.
