Asakawa Surf Forecast and Surf Report

Alright, this is Rusty.

First off, let’s be straight with you. The next week or so is pretty flat and quiet around Asakawa. We’re looking at a long stretch of tiny, weak surf from the 20th right through the 24th. Swell heights are mostly around 0.7ft to 1ft, with energy readings in the low double digits to seventies, so there’s just nothing doing. The water temp is sitting at 83°, which is a touch warmer than normal for this time of year, but that’s small comfort when there’s no waves.

We get a slight bump on the morning of the 25th, with a 1ft SE swell showing up, period around 16 seconds, and moderate energy of 136. The wind is glassy, so it’ll be clean. But honestly, it’s still very small. The 26th morning is similar—1ft SE, period 15 seconds, 133 energy—but again, it’s nothing to get excited about.

Then things start to get real. The morning of the 27th brings a solid change. Swell jumps to 4ft from the S, period 12 seconds, and the energy is strong at 586. The wind is glassy, so it’ll be clean. This is a proper groundswell, and the longer period means better shaped waves, but with a point break setup, it should handle it well. This is the first real standout.

The 28th morning pushes up to 8ft from the S, with a very long period of 14 seconds. Energy is huge at 3622, but the wind is cross-on, so it’ll be a bit bumpy. At 8ft, this is getting into expert territory, especially with that long period, which can make beach breaks close out but a point like Asakawa should handle it. The afternoon is 12ft S, 15 seconds, energy at 5128, but wind is picking up to 12 mph cross-on, making it choppy.

The 29th morning is the biggest—15ft from the S, period 15 seconds, energy at 9173. Wind is cross-on at 6 mph, so it’s not perfect, but it’s still powerful. The afternoon goes to 16ft S, 15 seconds, energy at 11609, with wind at 12 mph cross-on, giving it moderate chop. This is huge, expert-only stuff.

The 30th morning is 21ft S, 14 seconds, energy at 14941, but wind is onshore at 12 mph, making it poor. The afternoon is 26ft from SSE, period 13 seconds, energy at a massive 37238, but the wind is fresh cross-on at 19 mph, and the swell is simply too big for the break. That’s a solid pass.

The 31st sees a drop to 10ft SE, period 11 seconds, energy 2066, with a clean cross-off wind from the north at 19 mph. That’s a strong wind, but it’s offshore, so it’ll be clean. This is still big, but a good option for experienced surfers.

From the 1st of August onward, it drops back to tiny, weak surf again, with poor conditions and no real recommendations.

So the standout here is the morning of the 27th. That 4ft S swell with glassy wind is your best bet for a fun, clean session. The 29th morning is also a standout for the big wave crew, with 15ft S and long period, though the cross-on wind is a bit of a buzzkill. If you’re an expert, the 31st morning with 10ft SE and clean offshore wind is also worth a look.

Signing off, Rusty.
