Kodogawa Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are serving up for us.

First up, the water temp at Kodogawa is sitting at 84°F, which is a touch above the long-term norm for this time of year by about 0.5°F – nothing wild, just your usual warm bath.

Right now, we’ve got a bit of a lull. The first real chance to get wet is on Friday the 21st morning. It’s not going to blow you away, with clean glassy conditions and a small 3ft south swell, period around 9 seconds. The energy is pretty weak (203) – honestly, it’s just surfable, very ordinary stuff. That afternoon looks like a write-off with onshore wind and risk of storms.

Saturday the 22nd morning offers another tiny window: glassy again, but the swell drops to 2ft from the south. Combined energy is a measely 110. After that, Sunday and the rest of the weekend are pretty flat and poor.

Now, here’s where it gets interesting. Monday the 24th morning has a real glimmer of hope: glassy conditions, a clean 3ft swell from the southeast, but look at that period – 19 seconds. That is a proper groundswell, with a combined energy reading of 1040 (moderate). For a beach/sandbar break like Kodogawa, that long period means it could break a bit straight, but those waves will have some shape and power. It’s only small, but this is your standout for the week if you want clean, lined-up waves. The afternoon gets a big bump to 8ft but with onshore wind, so it gets messy.

Hold onto your board for Tuesday the 25th morning. We’ve got a 15ft southeast swell, 16-second period, and cross-offshore wind from the north-northeast. The combined energy is an enormous 9695 (very strong). This is for experienced surfers only – that’s heavy, powerful surf. The wave comment says it’s excellent for experienced surfers, and I’d agree, but the afternoon gets a bit unruly with cross-shore wind. If you’re not an expert, stay on the sand for this one.

After that, Wednesday the 26th is a write-off with howling onshore wind at 25 mph and rain. Thursday and Friday see the swell dropping but still with onshore winds, so marginal at best.

Looking into the second week, there’s a pulse on Thursday the 3rd of September. The morning is only 3ft but with a period of 22 seconds – an absolute monster groundswell. Combined energy hits 1771, but the wind is cross-shore, so it’s not perfect. The afternoon bumps up to 8ft with a 20-second period, energy at 4839, but again with cross-onshore wind. It’s promising, but less certain this far out. Friday the 4th morning might offer a window with 8ft from the east and a 15-second period, light cross-shore breeze. Worth watching, but don’t book the day off yet.

Overall, the clear standout is Tuesday the 25th morning for the big, powerful stuff, and Monday the 24th morning for a cleaner, smaller option. The rest is mostly a waiting game or for the die-hards.

Stay salty,
Rusty
