Asakawa Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s see what’s brewing for Asakawa over the next couple of weeks.

Right off the bat, we’ve got some serious, heavy water rolling in. A massive swell is hitting Thursday morning, August 6th, with waves around 15ft coming from the southeast. The ocean is absolutely thrumming with energy (8335), and that’s only going to build. The problem is, this is a big, raw, and powerful swell for a point break. The wind is up, too – a moderate cross-shore breeze – so it’s not going to be pretty. The water is a touch warmer than normal for this time of year, sitting at 84°.

By Thursday afternoon, things get even more intense. The swell pushes to 18ft from the southeast, with a very long period of 15 seconds, and the energy reading is a massive 21069. That’s a serious, deep ocean groundswell, but it’s just too much for this spot. The wind swings onshore, making it choppy. This is not a paddle session; this is big-boy, expert-only territory, and honestly, even for them, it’s a messy, dangerous proposition. This setup looks more interesting for kite surfing than paddle surfing.

Friday the 7th still holds a big 13ft SE swell, but it’s cross-onshore and choppy. The swell is still carrying a solid 13-second period, but the conditions are just poor. Saturday the 8th sees the swell drop to a more manageable 8ft, but the wind is still cross-onshore, and the quality is poor. The whole first week is a write-off for a clean, fun surf.

There’s a gap of a few days of poor-to-marginal conditions, but then we get a brief window. Tuesday morning, August 11th, the winds go glassy. The swell is down to a gentle 3ft from the SSW, with a 12-second period. It’s small, but it will be clean. The energy is weak (631), but for a logged-in, mellow session on a point break, it'll be there. The glassy conditions are the real highlight here.

The real standout, the one you’ve been waiting for, is Thursday morning, August 20th. The forecast shows a total glass-off: zero wind, clean as a whistle. The swell is a nice 4ft from the SE with a 9-second period. The energy is still modest (385), but the conditions are perfect. For a point break like Asakawa, with that optimum swell direction from the southeast, this is the best on offer. It’s an inconsistent break, so you’ll need some patience, but when a set comes through, it’ll be clean and lined up.

The Sunday before that, August 16th, also has some hope with a 7ft ESE swell under cross-offshore winds, but the period is short (7 seconds), so it’ll be a bit weak and bumpy. The 20th is the clear winner.

So, to sum it up: the first week is a no-go. The second week has some small, clean windows. The absolute best call is the dead-calm morning of Thursday, August 20th, at Asakawa. It’s not going to be epic in size, but it’s going to be perfect.

Rusty.
