Asakawa Surf Forecast and Surf Report

Alright, this is Rusty comin' to you live. Let's have a good look at what's on the cards for our local stretch at Asakawa (Japan). I’ve got a 16-day outlook right here, so let’s get into it, yeah?

This is a bit of a weird one, to be honest. The first few days look tidy enough, but we’re in for a long, quiet spell after that, especially into the second week. The early part of the window is where all the action is, with some clean chest-high stuff and light winds. After that kicks in, get ready for a lot of flat, small days that are barely worth the paddle out.

We start this week off nicely. Monday the 10th is looking like the stand out period. We’ve got chest-high sets coming from the S at 4 ft with a lovely 10-second period, and it’s clean with a light cross-offshore breeze from the NNE. The water is 84°, which is bang on average for this time of year, so no surprises there. The energy is solid too (513), enough to push you along nicely. It’s not a massive swell, but for a point break like this with good shape, that’s all you really need. Tuesday the 11th keeps that clean 3 ft S swell going, but the wind picks up a notch, making it a bit more of a cross-off, so still doable.

By Wednesday the 12th, we start to see the swell fading, dropping under 3 ft. Thursday and Friday slip into pretty ordinary territory with onshore winds and very weak energy readings down around 100 – 120. We get a brief glass-off on Friday morning the 14th, but the swell is barely breaking at 2 ft. Saturday the 15th pokes its head up with a clean 3 ft on the morning cross-off, but it feels like a tease.

Then from late next week, we hit a long flat spell. From around the 17th onwards, we’re getting a bit of a shift in swell direction (ESE), but the heights are tiny and the period drops to 6 seconds – that’s basically just wind chop. Not worth the effort. From the 19th of August all the way through to the end of the outlook on the 25th, the energy is below 150 most days, with heights barely scraping 3 ft. The 21st sees a bit of a lully 1 ft swell but with a period of 11 seconds – that’s nice energy but with that tiny height, it’s not going to do much here.

Honestly, if you don't get out Monday morning (10th) or maybe Saturday morning (15th), you’re looking at a big stretch of flatness with just a few tiny, glassy moments that are only good for a log maybe. For the rest of it? The setup gets so weak and small, with onshore winds on the afternoons, you might be better off on a kite board than a paddle board on those brief afternoons with a bit of SE wind. It’s a proper lull for Japan. Don’t hold your breath for the second week; forecasts can change, but right now it’s a write-off. For a point break, we need that S swell to stick around, but it just fades out.

Rusty out.
