Alright, Rusty here, letting you know how things are shaping up for our local stretch.
Alright, mate, let’s have a look at what’s on the cards for Kodogawa. It’s a bit of a slow-burner this forecast period, but there’s a real pulse of energy building if you’re patient. The water’s sitting at 78°, which is pretty much what you’d expect for this time of year, so no surprises there.
The first real chance for a wave comes Monday afternoon, July 6th. It’s a small, glassy start with a tiny 2ft swell from the ESE and a nice long 17-second period. The energy is low at 216, so it’s more about getting a feel for the water than catching anything substantial. The spot is inconsistent and can get crowded often, so keep that in mind. It’ll be a quiet session for the patient crew.
Tuesday morning, July 7th, is where it starts to get interesting. The swell picks up to 4ft from the ESE with a 13-second period, and the wind is dead glassy. The energy jumps to 491, and conditions are set to be clean. This is a solid option for a morning paddle before the afternoon storms mess things up.
Now, the standout sessions are Wednesday, July 8th, and Thursday, July 9th. Wednesday morning brings a 7ft SE swell with a long 17-second period, and it’s glassy again. The energy is screaming at 2566, which is significant. This is good power, but at over 8ft, it’s only for experienced surfers. The long period means those waves will have plenty of punch, and being a beach/sandbar setup, it might wall up and close out a bit. Thursday morning is even chunkier, with a 10ft SE swell and 15-second period, and again, glassy conditions. Energy is at 3589. This is big, powerful surf, and it’s definitely not a beginner’s game.
The middle of the week, from Thursday the 10th through Saturday the 11th, sees the swell peak but the wind turns cross-onshore, making things a bit messy. The swell gets up to 13ft on Friday afternoon with extreme energy levels (8193!), but with that cross-on wind, it’s going to be a ragged, challenging beast. This might be more of a kite-surfing show than a clean paddle session.
The weekend calms down a bit. Sunday the 12th has a drop to 5ft SSE swell with glassy conditions in the morning, but the energy is down around 746. It’s a decent window for a surf, but nothing compared to the midweek pulse.
After that, there’s a real lull. From Monday the 13th through the following weekend, the swell drops right off, mostly under 3ft. The wind is a mix of onshore and glassy, but there’s just no wave energy to work with. The combined energy values stay well below 300, so it’s flat and quiet. A long gap of several days with nothing to recommend.
There’s a flicker of hope around Monday the 20th and Tuesday the 21st of July. A new ESE swell pushes in, hitting 7ft on Tuesday morning with a 10-second period and glassy conditions. The energy gets back up to 805. It’s not the masterpiece of the 8th and 9th, but it’s a solid run of surf to close out the forecast period. Keep an eye on that.
So, the best bet by a long shot is the glassy, powerful mornings of Wednesday the 8th and Thursday the 9th of July. That’s the big, clean, groundswell energy you wait for.
Stay safe, and I’ll see you out there.

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.
