The Lowdown
Right, let’s have a look at what’s coming up for the next couple of weeks. To be straight with you, it’s not a classic run. The surf is going to be pretty inconsistent and on the small side for most of the period. We’ve got a few windows where it might get interesting, but you’ll need to pick your moments.
The first real chance to get wet is on Saturday the 5th of September. Kodogawa is a beach/sandbar setup, and it’s a sheltered spot, so it needs a bit of size to work. Saturday morning, we’re looking at 5ft of easterly swell, period around 8 seconds, which is short-period windswell. The combined energy is moderate at 390. The wind is cross-off from the NNE at 9 mph, which will keep things clean. The water temperature is 83°F, which is about average for this time of year. It’s surfable, but nothing to write home about.
Sunday the 6th of September is where the energy picks up. The swell builds to 7ft from the ESE on Sunday morning, with a period of 9 seconds (combined energy 669), and by Sunday afternoon it’s up to 8ft from the east, period 10 seconds, and the combined energy jumps to 1309. That’s strong wave energy. The wind is cross-off from the north both sessions, but it’s blowing 12-16 mph, so it’ll be a bit of a battle. The water is still warm. This is the standout of the whole forecast: Sunday afternoon has the biggest swell and the most energy. However, it’s a beach break with a short-period swell, so it’ll be a bit lumpy. That 8ft is solid and will be too much for beginners; it’s for the experienced crew. The consistent north wind will keep the faces clean, but it’s going to be a workout.
Monday the 7th of September still has some size, with 6ft from the east on the morning (period 10 seconds, combined energy 1064), but the north wind is 19 mph. It’s cross-off, but that’s a fresh breeze. The afternoon drops to 5ft. It’s marginal, but if you’re desperate, the morning has the better energy.
After that, the window slams shut. From Tuesday the 8th of September through to the end of the forecast, the swell drops away. The combined energy falls into the weak to moderate range, mostly under 300. The waves are small, with heights from 1ft to 5ft, and the period is mostly short (7-9 seconds) or very long (14-15 seconds) on a couple of days. That long-period stuff on the 12th and 13th of September will be too straight for the beach break, offering little shape. The wind is often cross-off or glassy, but there just isn’t enough swell to make it worthwhile. There are gaps of several days where the surf is just not worth paddling out for.
To be honest, if you see a big north wind and a bit of swell, it might look more interesting for a kite session than a paddle. The quality is just not there for most of the second week.
So, the one true standout is Sunday the 6th of September, specifically the afternoon. Get on it if you’re experienced and don’t mind a strong wind. After that, it’s a waiting game.

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.
