Asakawa Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s suss out what’s on the menu for Asakawa over the next couple of weeks.

We’re kicking off with a big, powerful pulse of swell that’s going to be a serious handful. The water’s sitting at a warm 85° – a touch warmer than normal for this time of year, so you can leave the steamer at home. This first run is for experienced crew only, and the wind is a real issue, making it messy. Things start to settle down for a brief window of proper glass, but then it fades out. It’s a tale of two halves.

Tuesday 4th August sees the first surf of the forecast, but it’s a tricky one. We’ve got a solid 10 ft swell from the ESE with a very long period of 16 seconds. The energy is massive (6633), but the wind is a light cross-on from the SE. That long-period groundswell will be trying to bend around the point, but the onshore kick will make it lumpy. Wednesday 5th gets even bigger with 15 ft to 16 ft of ESE/SE swell (energy pushing 11470) – that’s expert territory only. Cleaner cross-shore winds on Wednesday morning give a glimmer of hope, but the sheer size keeps it intimidating. This pattern holds through to Sunday 9th; the swell hangs around the 12 ft to 18 ft range, but every session is plagued by cross or cross-onshore winds, often with thunderstorms or rain. It’s a big, powerful, but messy setup.

Monday 10th is a write-off with poor conditions.

Then we get the moment. Tuesday 11th August morning. The swell drops to a much more manageable 6 ft from the S (period 12 seconds) and the wind goes glassy, coming from the ENE at just 6 mph. The energy is still moderate (2433), but the conditions are described as excellent for experienced surfers. This is the standout. The light offshore/glass makes it clean, and the holding power of a 12-second period on a point break like Asakawa should give some proper lines. The crowd factor is “sometimes” here, so you might have a few out, but for that quality, it’s worth it.

After that, the week goes quiet. Wednesday 12th and Thursday 13th mornings are glassy again but the swell is fading fast – down to 4 ft to 4 ft, with energy under 650. Nice for a longboard or a foiler, but not a lot of push. Friday 14th stays clean but small.

There’s a gap of a few days without much to get excited about before a new, short-period swell tries to build from the ESE on Saturday 15th August. It’s 8 ft but with a period of only 7-9 seconds, and the wind is cross-on from the SE. The energy is moderate (895-2072) but the short period means it’ll be lumpy and weak. This one runs through the weekend, but it’s marginal at best. By Monday 17th, it’s fading again.

The best bet is absolutely Tuesday 11th morning. Get on it before the swell dies.

Rusty.
