Asakawa Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at the next 16 days for Asakawa. It’s a point break that’s fairly exposed to the open ocean, with an optimum swell direction from the southeast, but it’s inconsistent – it doesn’t fire all the time. Right now, the water temperature sits at 28°, which is about average for this time of year, so nothing unusual there.

The first few days are a bit of a write-off. Thursday the 20th and Friday the 21st have tiny, weak swell – only 1ft to 3ft – and the combined wave energy is very low at 48 to 193. The wind is glassy in the mornings, which is nice, but the waves are just too small and ordinary to bother with. Saturday and Sunday the 22nd and 23rd are similar, with small 2ft to 3ft swell and light glassy mornings, but the energy stays weak (107 to 181), and the conditions are just "surfable but very ordinary." It’s a flat spell, no doubt.

Then Monday the 24th starts to get interesting. The swell jumps to 6ft from the southeast, with a solid 17-second period, and the combined energy rockets up to 2600 – that’s moderate, and it has real punch. The morning is glassy, and these are excellent conditions for experienced surfers. The wind is light and glassy, so it’ll be clean. The afternoon gets a bit onshore but still 8ft from the same direction, though the energy is massive at 4107. The period is very long, which means Asakawa, being a point break, will handle it well with long, peeling waves.

But the standout, the absolute one to circle, is Tuesday the 25th. Morning sees 15ft of southeast swell, a 17-second period, and the combined energy hits a massive 11759 – that’s strong. The wind is off the northeast, so it’s cross-offshore and clean. This is exceptional surf, but it’s only for experts – 15ft is way too big for beginners. The afternoon is even bigger at 16ft, but the energy is 15454, and the wind goes cross-onshore, making it a bit messier. The morning is the pick.

After that, things go downhill fast. Wednesday the 26th brings heavy rain and strong onshore winds with 18ft swell, but it’s choppy and poor. The wind is 20-25 km/h from the southeast, and the energy is still high but the quality is gone. Thursday the 27th is similar with 13ft and strong onshore winds – more of a kite surfer’s playground than a paddle surfer’s. The rest of the week into early September sees the swell dropping back to 3ft to 7ft, but the wind is often onshore or cross-onshore, and the energy drops to between 44 and 1122. Conditions are marginal or poor, and there’s a long gap with no real quality.

There is a glimmer right at the end. Monday the 31st of August has a 5ft southerly swell with a 13-second period, glassy wind, and combined energy of 1081 – that’s good quality. Tuesday the 1st of September has a 4ft south swell with clean offshore wind, but it’s smaller. Still, it’s a nice way to finish the outlook.

So, the best on offer is clear: Tuesday the 25th of August, early morning, at Asakawa. It’s big, it’s clean, and it’s got that long-period southeast groundswell. If you’re an expert, that’s the session. The rest is small, blown out, or just plain ordinary.

Rusty.
