Kamakura Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s run it down. The first week is a total dud. From now through the 5th of September, the swell is flat, tiny, and weak. Water temp is a balmy 82°, which is a bit warmer than usual for this time of year.

We’re looking at a stretch of nothing until the 6th of September. The swell is all under 2ft, mostly from the south or southeast with short periods. The wind is mostly cross or onshore, and the wave energy is weak. There’s a glassy moment on the morning of the 4th, but with only 1ft on offer, it’s not worth the paddle out.

Then things crank up. On the 6th of September, early Sunday morning, we get a fresh offshore wind from the north at 22 mph, and the swell jumps to 4ft from the south with a solid 14-second period. The combined energy is moderate (491). This is a groundswell with some real grunt. The afternoon holds the same quality, with the wind still offshore. The water is clean, and the height is just over 3ft, so it’s not too big for a confident beginner.

Monday the 7th is the real standout. The morning kicks off with a moderate offshore breeze and a 4ft south swell, period 14 seconds. The combined energy is strong (638). This is the best of the run. The waves will have proper shape, good power, and that long-period energy means nice, clean lines. The wind stays favorable into the afternoon, though it swings cross-offshore. This is a solid option for intermediate to advanced surfers.

The quality holds through the 10th and 11th of September. On the morning of the 10th, we’ve got 4ft from the SSE with a 12-second period, and the combined energy is strong (518). The wind is a gentle cross-offshore breeze, keeping it clean. The 11th morning looks even better, with a 4ft south swell at 13 seconds and a combined energy of 543. The wind is almost glassy (3 mph). It’s a real sweet spot.

After that, the 12th and 13th drop off a cliff. The swell drops back to 3ft and 2ft, the energy weakens, and the wind gets messy. It’s a wrap.

So, the call is simple. The best surf on offer is the morning of the 7th of September, with that 4ft south swell and strong offshore winds. The consolation prize is the morning of the 11th, which is also very clean, but a little less punchy. Get on it while it’s good.

Rusty.
