Kamakura Surf Forecast and Surf Report

G’day, I’m Rusty.

Alright, so for the Kamakura outlook we’re looking at a rough 16-day run with only a couple of real windows to get excited about, and they’re both early on. The rest of the forecast is flat and ordinary, so you’ll need to be ready to move when the time is right.

We start off Monday the 7th of September with a bit of grunt but messy conditions. The water’s sitting at 83°, a touch warmer than usual for this time of year, so it’s a little extra muggy out there. Monday morning has heavy rain and a light cross breeze (6 mph) with a solid 6 ft south swell and moderate wave energy (497). It’s a marginal surf call though—not the cleanest. Then Monday afternoon the swell jumps up to 10 ft from the south, with strong energy (2898), but that’s simply too big for this spot, so only for the experts if you’re game, though wind and tide are favourable.

Now, the standout for the whole period is Tuesday the 8th of September, morning session. Kamakura is an exposed beach setup that picks up south swells best. The sky’s clear, wind is light from the NNW at just 3 mph and glassy—dead flat water. The swell holds at 4 ft from the south, period 9 seconds, with moderate energy (550). It’s clean, head-high or so, and the best quality we’re going to see all forecast. Crowds can be a thing here sometimes, so get out early if you can. For beginners, this is a great window—4 ft is not too big.

Tuesday afternoon goes to junk fast: risk of thunderstorms, strong onshore wind (16 mph), and the swell drops to 3 ft from the SSE. Poor conditions. Wednesday the 9th has some hope on the afternoon—offshore wind (NNW, 12 mph) with a 5 ft south swell and clean lines, but the morning looks choppy and messy with a cross-onshore breeze. Thursday the 10th brings moderate offshore winds, but the swell is small at 3 ft–3 ft and short period (8 seconds), only surfable but very ordinary.

From Friday the 11th right through to the end of the forecast on the 22nd of September, it’s flat and dead. You’re looking at waves under 2 ft most days, with periods dropping as low as 7 seconds, and combined energy rarely cracking 100. There are a few glassy moments on the weekend of the 13th–14th, but there’s just no swell to ride. Even the longer-period pulse on the 16th (13 seconds) brings only 0.7 ft—not enough to work with. For an exposed spot like Kamakura, this kind of blank run is normal for the season, so don’t lose hope—forecasts can change, but right now, Tuesday morning is your only true play.

Stay tuned.
