Omaezaki Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s in store for Omaezaki (Japan) over the next couple weeks.

First up, the start is a bit sleepy, but there’s a few windows to wet a line. Thursday morning, September 3rd, you’ll find glassy water and a 2ft easterly swell with an 11-second period. Combined energy is moderate (222). It’s small but clean. Water temp’s about average for the season. Could be a few others out—crowds show up sometimes.

Thursday arvo the wind swings cross-onshore and ruins it. Skip it.

Friday morning, September 4th, is the early highlight. Some clouds, glassy again, with a 4ft south-southwest swell at 10 seconds. Combined energy hits moderate-strong 421. Clean, fun, beginner-friendly. Friday arvo stays clean with cross-off wind.

Saturday 5th has fresh offshore wind all day, but the swell’s only 3–5ft with short period (7–9 seconds) and tide issues. Clean but average. The 5ft later might be a touch much for beginners but doable.

Sunday 6th is a total blowout—gale-force offshore winds, tiny 1–2ft swell, weak energy (82–86). Not worth paddlin’ out.

Monday 7th brings cleaner but marginal waves—5–5ft from the east then south-southeast, period 8–9 seconds. Fresh cross-off wind keeps it clean-ish, but quality is only so-so with storms possible.

Tuesday 8th sizes up to 8ft in the morning from the south, period 10 seconds, strong energy (1142). But the wind goes cross-shore and gets messy, with 8ft and strong chop by arvo. That’s expert-only size, and the wind kills it.

Wednesday 9th is huge—13ft in the morning, south-southeast, 11-second period, very strong energy (3822). But it’s cross-onshore and lumpy. That’s a kite-surf day, not for paddle-surfers. Too big and messy for everyone but the hardcore.

Thursday 10th stays big at 8–8ft, onshore wind, poor conditions.

Then there’s a quiet spell—Friday 11th and Saturday 12th are small or average, though Saturday 12th morning has a little gem: 2ft but a 14-second period from the east, gentle offshore, moderate energy (286). Clean, long-period groundswell—nice for the reef, but sets will be spaced.

Sunday 13th morning: 3ft southerly, 10 seconds, gentle offshore, moderate energy (414). Clean and fun.

Monday 14th morning: 3ft from east-southeast, 9 seconds, moderate offshore, moderate energy (324). Clean again.

The standout to watch is Friday morning, September 18th. This is a long way out, so don’t bank on it, but the signals are strong. 8ft of south-southeast swell, 15-second period—very long-period groundswell. Combined energy is very strong at 2887. Wind is a light air from the north-east, glassy. That’s excellent surf for experienced surfers only—too big for beginners. For the crew that knows, Omaezaki could be a gem with that south swell and offshore breeze.

There are a few days with no real options—the 10th, 11th arvo, 15th, 16th, and 17th—so expect some quiet days before that possible standout.

Your best safe bets are the mornings of the 4th and 13th for clean, small waves. The 18th is the one to dream on.

Rusty.
