Asakawa Surf Forecast and Surf Report

Alright, let’s break it down. This is Rusty, and I’m looking at the outlook for Asakawa, a point break that’s got decent exposure. The water’s around 83°, which is about normal for the season.

The first week is a total dud. From Monday the 17th through Thursday the 20th, there’s no real surf to speak of. Swell is tiny, under 3 ft, with onshore wind and weak energy – the combined energy is just 81 to 194, which is pitiful. You’re better off doing something else.

Friday morning the 21st is the first real chance. The wind goes glassy, and we’ve got 4 ft of south swell with a period of 11 seconds. The energy jumps to 472, which is moderate and clean. But it’s a short window – the afternoon turns poor, and the rest of the weekend into Monday the 24th is mostly messy with cross-on or cross-off winds and small, weak surf. Not worth chasing.

The standout window is the last week of August and into September. Tuesday morning the 25th brings 4 ft of SE swell with a period of 14 seconds – that’s a proper groundswell – and clean cross-off winds from the NE. The energy is strong at 617. This is a good one, but it’s just the warm-up.

The real standout is Wednesday the 26th afternoon. We’ve got 8 ft of SE swell, a period of 17 seconds – that’s a very long-period groundswell – and the wind goes glassy. The combined energy is 3112, which is strong. This is excellent surf for experienced surfers. The point break at Asakawa loves a long-period SE swell, so the shape should be solid. But keep in mind, this is a big swell, over 8 ft, so it’s only for experts.

Thursday the 27th and Friday the 28th build even bigger, with 10 ft to 13 ft SE swell, but the wind is cross-off and a bit stronger. The energy is huge – 5103 to 8617. These are expert-only days, and the long period might make it a bit tricky, but if you’re skilled, it’ll be a session to remember.

Saturday the 29th is the peak of the run, with 16 ft SE swell and a period of 16 seconds. The energy is massive at 11713 to 12378. This is only for the brave, and the wind on Saturday morning is glassy, which is a massive plus. But again, 16 ft is pure heavy-water territory.

After that, Sunday the 30th morning drops to 15 ft with glassy wind, and Monday the 31st morning has 8 ft from the south with a period of 13 seconds and glassy conditions – that’s a more manageable size for experienced surfers, and the energy is still strong at 3160.

The best on offer is without a doubt Wednesday the 26th afternoon and Thursday the 27th morning for the combination of clean wind, solid size, and that long-period SE groundswell. But remember, Asakawa can get crowded at times, so get in early if you’re chasing the good ones.

Rusty.
