Onjuku Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cooking at Onjuku.

Right off the bat, the next few days are a bit of a write-off. There’s some small swell bumping around, but the wind is all wrong—cross-on, onshore, or just messy. Water temp is sitting about average for this time of year at 79°, so at least you won’t be shivering while you wait for nothing.

The first real glimmer of hope comes on Saturday morning, the 5th. A clean 4ft swell from the east with a short period of 6 seconds, but with offshore winds. The energy is pretty weak at 232, so it’s more of a novelty wave than a solid session. It’s inconsistent here at Onjuku, so don’t expect much.

Saturday afternoon pumps up to 5ft, but the wind gets messy again. Sunday morning, the 6th, sees 7ft east swell, but again, wind is a problem. The energy is starting to build, hitting 470, but the onshore flow is keeping it lumpy.

Monday the 7th is interesting. We’ve got strong offshore winds, a solid 6ft to 6ft east swell, and the energy is cranking at 534 and 461. The period is still short at 8 seconds, so it’s going to be a bit crumbly, but it’s clean. This is a good window for the intermediate crew. The wind is strong, so paddling out will be a workout, but the waves will be clean.

Tuesday the 8th turns ugly. The onshore wind comes back with a vengeance, and a 7ft SSE swell with an 11-second period gets completely shredded by a 28 mph cross-on wind. The energy is massive at 1266, but it’s a mess. Skip it.

Wednesday the 9th is a weird one. The swell is huge—16ft on the morning with a 12-second period, and the energy is off the charts at 7241. But the wind is cross-on, making it choppy and dangerous. This is big, powerful, and messy. It’s not a paddle-surfing day unless you’re a masochist or a kite surfer. The afternoon drops to 15ft, but the wind is howling onshore.

Thursday the 10th is the standout. The morning is still a bit cross-on with 10ft S swell, so it’s not perfect. But the afternoon? That’s the session. The wind goes glassy, the swell drops to a clean 6ft from the SSE with a 10-second period, and the energy is solid at 824. This is the best on offer in the whole forecast. Expect very good surf conditions. The crowds are possible here, so get out early.

After that, Friday the 11th is a drop-off. The swell fades, and the wind is clean but the waves are small.

Saturday the 12th sees a spike in swell again. 8ft from the NE with a clean offshore wind in the afternoon. The energy is high at 934, but the period is short at 8 seconds. It’s a solid option, but the period holds it back from being a classic.

Sunday the 13th is another good one. Morning has 8ft from the ENE, a light offshore breeze, and very good surf conditions expected. The energy is 850. This is a proper session for the intermediates.

The following week gets messy again. A big 10ft+ SSE swell returns on Wednesday the 16th, but it’s too big for this break and the wind is not ideal. By Thursday the 17th, we’re into gale-force offshore winds, which is just nasty.

So, to wrap it up: the best windows are Thursday afternoon the 10th for glassy, clean conditions, and Sunday morning the 13th for a solid, clean east swell. Get on it.

Rusty.
