Asakawa Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Asakawa over the next couple of weeks.

First off, the water temp is sitting at about 84°F, which is pretty much what you’d expect for this time of year. Nothing wild there.

The opening part of the forecast is a bit of a slow burn. Sunday afternoon the 23rd has a tiny 1ft swell from the SE, but the wind is onshore and it’s just poor. Not worth paddling out for. The real action doesn’t kick off until Monday morning the 24th. That’s our first standout.

Monday morning the 24th is where you want to be. We’ve got a clean 4ft SE groundswell, with a lovely 19-second period, and the wind is off the land – glassy conditions. The combined energy is pumping at 1288 (moderate), and the report says “expect very good surf conditions.” That’s a proper session. Asakawa is a point break, so that long period groundswell will wrap in nicely. Just keep in mind it can get a bit inconsistent here, and crowds are possible, so get in early.

The swell builds through the week. Tuesday morning the 25th sees 10ft from the SSE at 14 seconds, but the wind is cross-onshore, which messes it up a bit. That’s a lot of power (3685 energy), but it’s not clean. Wednesday the 26th is similar – plenty of size but cross-on winds. The swell stays solid through the end of the month, but the wind is a problem. We get a few glassy mornings on the 28th, 29th, and 30th with smaller 2ft to 3ft swell, but it’s very ordinary, weak energy (around 100-200). Not much to write home about.

Then we hit a bit of a lull. The first few days of September are quiet, with small waves and onshore winds. The next real standout pops up on Wednesday morning the 2nd of September. Now we’re talking. The swell is 6ft from the S at 14 seconds, the wind is cross-offshore from the NE, and the energy is strong at 1675. The report says “excellent surf conditions for experienced surfers.” That 8ft+ threshold is for experts, but at 6ft this is a solid intermediate session. The direction is S, which matches the optimum swell direction for Asakawa (SE is close enough). This is the pick of the second week.

Thursday morning the 3rd of September is another good one. Similar 8ft S swell, 13-second period, cross-offshore wind, and strong energy at 2165. Again, it’s for experienced surfers, but the conditions are clean. The wind stays favorable through the 4th, but by the 5th and 6th, a strong onshore breeze from the E and SSE ruins it, with the swell getting messy and lumpy. That’s the end of the run.

So, to sum it up: your best bets are Monday morning the 24th for clean, glassy, long-period fun, and Wednesday morning the 2nd of September for a bigger, cleaner groundswell session. After that, the wind turns ugly and the swell drops off. Get it while you can.
