The Lowdown

Alright, Rusty here, let's talk about what's on the cards for Kodogawa over the next couple of weeks.

Straight up, this is a pretty quiet start for the sandbar. We’ve got a few days of tiny, weak surf to kick things off, but nothing worth paddling out for until we get into the first week of August. The energy is just not there in the beginning.

Friday the 31st through to Saturday the 1st of August are a write-off – flat, weak waves, with the combined swell energy sitting at only 45 and 29. There’s just nothing doing. Sunday morning the 2nd sees a little bump, with a 2 ft swell from the ESE and a long 16-second period, pushing energy up to 199. It’s glassy, which is a bonus, but the waves are just too ordinary to get excited about.

Now, Monday the 3rd is where things start to get interesting. The swell builds to 5 ft from the ESE, with a 16-second period, and the combined energy jumps to 1103. The wind is cross-shore, but light. It’s still a bit marginal, but for the more experienced crew, there’s potential for some fun, lined-up waves. This is a so-so start, but it’s the best we’ve seen. The water temperature is about average for this time of year, so no shocks there.

The real standout, and the only one I’d call a true highlight, is Thursday the 6th of August. The swell is pumping from the ESE at 25 ft to 26 ft, with a 19-second period and a massive combined energy of 38,356. This is serious, powerful groundswell. However, the wind is a fresh cross-onshore breeze, which will chop it up, and the forecast explicitly says the swell is too big for this break. This is experts-only territory, and even then, it’s going to be a wild, challenging session. The long period will make it a bit walled-up at the beach, but for the few who can handle it, there will be some bombs.

Wednesday the 5th also has solid size at 13 ft to 16 ft, with energy up to 10,325, but the wind is less favourable, and the quality is still marginal. The run from the 8th of August onwards drops off quickly, with the swell backing down to 12 ft but cross-on winds and poor conditions spoiling the party. By the 10th, we’re back to weak, choppy surf, and the second week looks mostly flat with small, messy waves and poor conditions.

So, to keep it simple: don’t bother until at least Monday the 3rd. The best shot is Thursday the 6th, but it’s a big, heavy, challenging swell that’s really only for the hardcore crew. The rest of the window is a write-off.

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.
