Onjuku Surf Forecast and Surf Report

Alright, grab your board. This is Rusty, looking at the Onjuku stretch.

Right off the bat, for the next few days, Onjuku is going to be a bit of a tease. We've got surfable waves, but nothing that's going to have you calling in sick. The water temp is sitting at a normal 80°, nothing wild there. The swell is pretty weak, with combined energy readings mostly in the 200s and 500s (weak to moderate), so it's going to be a grovel-fest for the most part. The wind is a bit of a mixed bag too, with a fair amount of cross-off and cross conditions. Thursday the 13th is looking clean, but that energy is just not there. Don't get too excited for the weekend either, the energy picks up a touch but the wind turns more cross, making things a bit lumpy.

Things get quieter and weaker going into the middle of next week, with the swell dropping out and energy readings falling below 250. It’s not looking great, to be honest. There's a bit of a flat spell from around the 18th to the 23rd where I’d be finding something else to do, maybe fixing your dings. The swell energy is really weak, some days dropping to triple digits (like 103 and 62), and the wave heights are down around 1ft to 3ft. It’s a proper lull.

Now, here's where it gets interesting. There’s a promising pulse on Monday the 24th. The wind goes offshore early, and then in the afternoon, it’s glassy, absolutely clean. The swell comes back up around 4ft from the SE with a long 12-second period, and the energy jumps to 640 (moderate). This is the first real standout of the window.

But the real good stuff, the one we've been waiting for, is that big arrival on the 26th. That Wednesday morning is the one. We’re looking at a solid 7ft of SE swell with that same long 12-second period, and it's glassy. The energy is strong at 1452. This is going to be the pick of the whole stretch, and it’s the best wave you’ll find in the next couple of weeks. Just know that this size will be pushing it for anyone who isn’t comfortable on a bigger day.

After that, it gets big, but it gets messy. By the 27th, we’re talking about 13ft to 15ft of swell from the SE with 14-second periods. Power wise, we’re looking at strong to very strong energy readings of 6514 and 7885. But, this is way too much juice for Onjuku. It’s going to be a washing machine, not a surf spot. The wind is forecast to be on it, and conditions will be poor. Then by the 28th, the wind is howling onshore, and it’s blown out. That big swell is just going to be a messy, dangerous close-out. Unless you’re a masochist with a jet ski, give it a miss.

So, to sum it up: the 24th afternoon is a nice warm-up. The standout has to be the morning of the 26th – that’s the one to circle on the calendar. The swell direction is SSE which is good for this spot, it has size, period, and clean glass. After that, it’s just too much of a good thing.

Rusty, out.
