Onjuku Surf Forecast and Surf Report

Alright, this is Rusty. Let’s talk surf for Onjuku.

Right off the bat, the water’s running a bit colder than normal for this time of year, 72°F, so you might want a spring suit.

The first few days are pretty average. Monday the 6th and Tuesday the 7th offer some waist-high swell, but the wind is messy and cross, so don’t expect much. There’s decent energy in the water though, with the combined energy reading 509 (moderate) on the 6th, building to 895 on Tuesday morning. Still, not worth paddling out for if you’re chasing quality.

Wednesday the 8th morning is where it starts to get interesting. A solid 7ft southeast groundswell with a 16-second period rolls in, and with light east-northeast winds, it’s cross-off and clean. The combined energy jumps to 2444 – that’s proper strong. This is the standout session for the week. Onjuku will be handling that long-period swell well, but that size and period mean it’s for experienced surfers only. Anything over 8ft is expert territory, and at 7ft, it’s still pushing limits. Crowds are likely to be around, as it’s inconsistent here but when it fires, everyone knows.

From Thursday the 9th through to Sunday the 12th, the swell stays strong, 7ft to 7ft, but the wind swings onshore from the south and southwest. The combined energy stays high, between 1708 and 2924, but it’s wind-affected and choppy. Not the clean lines you want.

Then we hit a lull. From Monday the 13th of July through to Wednesday the 15th, it’s pretty grim – onshore winds, dropping swell, poor conditions. Combined energy drops below 1200, and the scores reflect it. That’s about three days of flat, blown-out surf.

Thursday the 16th morning offers a little window. Glassy conditions with a light west-southwest breeze, 5ft swell from the east-southeast, period 11 seconds. Combined energy is a moderate 593. It’s clean, but the swell is weaker and shorter period – it’ll be fun for a cruise, but nothing epic.

Friday the 17th morning goes glassy again, with a calm wind and 3ft east-southeast swell. Combined energy is just 266. Small and clean, good for a longboard or a beginner session.

The final weekend, Saturday the 18th and Sunday the 19th, brings another change. Sunday morning the 19th sees a 5ft east-southeast swell with a short 9-second period and a light north-northeast offshore wind. Clean conditions. The combined energy is low at 355, but it’s rideable. Monday the 20th keeps that 5ft east swell rolling, with clean cross-off winds and combined energy around 327. Short period, so it’ll be a bit fat, but fun.

Tuesday the 21st? More of the same, 5ft to 5ft, but the wind picks up to a moderate breeze. Not bad, but not great.

Overall: the real standout is Wednesday morning, July 8th. That’s the one to circle. After that, it’s a mix of clean smaller days and blown-out bigger days. Nothing else truly fires.
