Asakawa Surf Forecast and Surf Report

G’day, it’s Rusty here.

Let’s be straight with you—this outlook for the next couple of weeks is a bit of a mixed bag, but there is some serious potential hiding in the back half. The start is dead, absolutely dead. We’re looking at a solid blank run of about eight days where there’s just nothing worth paddling out for at Asakawa. The swell is tiny, the wind is mostly onshore or cross-onshore, and the energy in the water is weak, with combined swell energy values mostly in the double digits, struggling to break past 100. We’re talking knee-to-waist high slop, man. Save your energy.

The first real glimmer shows up on Friday the 21st. We see a pulse of S swell pushing the wave height up to 5ft, but the period is a short 11 seconds. The combined energy jumps to a moderate 548, but it’s just not enough to clean it up. The wind is light but cross-onshore, making it lumpy and weak. It’s marginal at best, a real maybe-morning-session kind of call.

The next week stays pretty lackluster. There’s some inconsistent SSW swell, but it’s small and messy. The water hit 83°F at the start of the period, which is right on the average for this time of year, so nothing weird there.

Now, pay attention because this is where it gets interesting. The standouts are on Monday the 24th and Tuesday the 25th. A proper, long-period SE groundswell rolls in. We’re talking 16 second period. Monday afternoon sees 7ft waves and the combined energy jumps to a strong 1989. It’s big and it’s powerful. Tuesday morning is still big at 8ft, and then the magic window hits Tuesday afternoon. The wind goes glass, absolutely glass, and the swell holds at 8ft with 16-second period. The energy is pumping at 3699. This is the best conditions for experienced surfers, full stop. This is the one to circle. This point break at Asakawa is going to have some proper lines, especially with that long period. It’s a point break, so it should handle the long-period energy well. But heads up, this is inconsistent, and with a swell this size, it’s pushing into expert territory. This is not for beginners.

The run continues into the rest of that week. Wednesday the 26th is still solid, but the wind turns onshore. Thursday the 27th, though, is another gem. We’re seeing 12ft of SE swell and the wind goes cross-offshore from the NE in the morning. The energy is massive, a very strong 5343. That’s going to be a beast of a day, big and powerful. Again, for experts only.

Don’t get too excited about the weekend, though. Friday the 28th turns to garbage. The wind howls onshore from the E at 19 mph and the swell jumps to 13ft, but it’s messy, lumpy, blown-out chaos. Then Saturday the 29th is just ridiculous. It’s way too big, with 25ft of SE swell and 25 mph onshore winds. That’s not surfing, that’s a survival mission. Even the forecast is telling us it’s too big for the break. It’s more of a kite-surfing day with that much wind and swell.

The very end of the window, Sunday the 30th and Monday the 31st, backs off a bit. The swell drops back to 10ft and 12ft with cross-offshore winds, so it cleans up nicely, but the period drops back down to 9 seconds. It’ll still be fun and powerful, but not the perfection of the earlier days.

So, bottom line: the first week is a write-off. The second week, from the 24th through the 27th, is where the real deal is. The absolute standout is Tuesday the 25th afternoon. Get on it, but be ready. This is big, serious surf.

Rusty, out.
