The Lowdown
Alright, let’s get into it. For the next 16 days, there’s a long quiet spell before things really fire up, so patience is the name of the game.
First up, we’ve got a real dry patch. From Saturday 25th July right through to Monday 3rd August, Kodogawa is basically a write-off. The swell is tiny, around 1 foot to 2 feet, and even though we get glassy mornings – especially on the 28th and 29th with dead calm conditions – the wave energy is just pathetic. The combined energy is barely hitting three digits at best (86 to 124), and most days it’s weak. The water temp is about average for the time of year, nothing wild. The swell is coming from the SE, which is the optimum direction for this sheltered beach/sandbar setup, but with that little size and the period being short (9 to 11 seconds), there’s nothing to get excited about. Crowds are often around here, but honestly, nobody’s paddling out.
We get a little bump on Monday 3rd August morning. The swell picks up to 3 feet from the ESE, and with a period of 12 seconds, there’s a touch more energy (253). The wind is glassy, and the conditions are surfable, but it’s still very ordinary. Not a standout.
Now, hold onto your board. The real action kicks off on Tuesday 4th August. The morning brings a solid 7 feet ESE swell with a very long period of 17 seconds (combined energy 2743). The wind is glassy, so the waves will be clean and powerful. This is good for experienced surfers, and with that long period, it’s going to be a proper groundswell, best handled at a point or reef – but this is a beach/sandbar, so it might break a bit straight. Still, a standout morning.
Then Wednesday 5th August morning is even better. We’re looking at 12 feet from the ESE, period 19 seconds (combined energy 7937). The wind is glassy again. This is big, powerful, and for experts only. If you’ve got the skills, this is the pick of the whole window. The crowds are often here, but on a morning like this, only the brave will be out.
Thursday 6th August morning is the biggest of the lot. 15 feet from the east, period 18 seconds (combined energy 13977). Glassy wind. This is exceptional, but it’s only for expert surfers – way too big for anyone else. The swell direction is slightly east of optimum, but with that size and period, it’ll still be a monster.
After that, the swell drops fast. Friday 7th August morning sees a 3-foot east swell, period 12 seconds (278), glassy, but it’s back to very ordinary.
Saturday 8th August morning offers a bit of a change: 4 feet from the SSE, period 10 seconds (443), with a cross-offshore wind from the NNE. That’s clean and should give some decent, surfable waves.
Sunday 9th August morning is a solid 7 feet from the SSE, period 9 seconds (913), with a clean cross-offshore wind. That’s a good, punchy short-period swell, and it’s for the more experienced crew.
So, the clear standout window is the mornings of Tuesday 4th, Wednesday 5th, and Thursday 6th August. If I had to pick just one, Wednesday 5th morning is the absolute best on offer – big, glassy, and powerful. Get on it.

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.
