Asakawa Surf Forecast and Surf Report

Alright folks, Rusty here. We’ve got a 16-day window for Asakawa, and it’s a real mixed bag—a front-loaded pulse of serious size that fades fast, then a long wait for the next decent one.

The first few days are the highlight, but only for the experienced crew. Sunday morning, the 12th of July, is the standout. You’re looking at a solid 10ft groundswell from the SSW with a very long period of 16 seconds pushing in. The combined energy is pumping at 4895, which is seriously strong. Best part? It’s glassy, dead calm wind. That’s a recipe for some heavy, powerful lines at this point break. The water is a bit colder than normal for this time of year, sitting at 77°. This is expert territory only, mind you—that size with that period will be a handful.

Sunday afternoon holds up nicely with 8ft SSW swell and still glassy, just a risk of storms. The energy drops to 2771, still strong. Monday morning, the 13th, we’re down to 5ft but still a solid 12-second period, glassy and clean—expect very good surf. It stays rideable through Monday afternoon at 5ft, but after that, the swell drops off a cliff.

From Tuesday morning, the 14th, through the rest of the week, it gets small and ordinary. We’re looking at a run of poor conditions or very marginal surf, with the swell dipping below 3ft and the energy dropping into the low hundreds or even double digits. It’s a long gap of flat to tiny waves for about four days.

Then, just when you think it’s over, Saturday morning, the 18th of July, brings a new pulse: 6ft from the ESE with a 13-second period. Energy is back up to 939, moderate. It’s a bit lumpy with a cross-onshore wind, so it’s marginal, but it’s something. An interesting note: Sunday morning, the 19th, shows a clean 8ft ESE swell, glassy calm, but it’s a short 9-second period—good energy at 1595, but that short period might make it a bit crumbly and less organized. It’s a promising option for experienced surfers again, but it’s a week out, so a bit less certain.

The rest of the second week looks small and mostly poor, with only a few glimmers of small, clean, but weak waves. Not much to write home about after that Sunday peak.

So, bottom line: the best on offer is the Sunday the 12th through Monday the 13th—big, powerful, and clean. Then a long wait for a decent but less reliable pulse around the 18th-19th. Get on it early if you’ve got the skills.

Rusty.
