Suruga Bay Surf Forecast and Surf Report

Alright, let’s talk Suruga Bay. It’s the only game in town, and the first week is a total dud. Tiny, weak, onshore slop with barely any energy. Water temp is 27°, about average for the time of year, no big deal.

From Monday 17th through Saturday 22nd, waves are under 3 feet, mostly from the SSW, periods around 6 to 10 seconds, and the wind is all over – mostly onshore or cross-onshore. The combined energy barely hits 100 most days, just weak and messy. Not worth getting wet.

Sunday 23rd morning shows a little life. Still only 3 feet, but the wind swings cross-offshore from the NNE, cleaning things up. The combined energy hits 103 (moderate). It’s rideable but barely. Monday 24th sees a bump – 6 feet in the morning from the SW, but with a short 7-second period, it’s going to be a bit of a mess. The wind is cross-off again, so it’s clean, but the quality is still marginal.

Now, Tuesday 25th morning is a real standout. Glassy conditions, dead calm wind, and a long-period groundswell from the SE at 14 seconds. Combined energy is 329 (moderate but solid). Only 2 feet, but that period and glassy surface will make for some surprisingly tidy lines. The swell direction is SE, a bit off the optimum SSE, but the clean conditions and long period make up for it.

Then the big stuff starts Wednesday 26th. The swell jumps to 5 feet in the morning, hitting 6 feet by afternoon, both from the SSE with a very long 17-second period. Combined energy rockets to 1613 (strong). This is proper groundswell – the kind that’ll push through and wrap around the breakwater. The caveat: with that long period, it might be a bit too lined up for a beach break, but on a breakwater, it could be magic. The morning has light cross-shore wind from the ENE, so it’ll be a bit rippled, but still surfable.

Thursday 27th and Friday 28th get bigger – 7 feet to 10 feet – but the wind goes nasty. Fresh to strong cross-shore and cross-on, making it a lumpy, chopped-out mess. Combined energy hits 4,000+. This is too big and blown out for most, and at these sizes, only experts should even look at it. The period stays long (16-17 seconds), so it’s got power, but the wind is a killer.

Saturday 29th morning is a real standout for experienced surfers. 12 feet from the SSE, 15-second period, combined energy at 5103 (very strong), and clean cross-offshore wind from the WSW. That’s a proper big-wave session – but only for the crew who know what they’re doing. The afternoon turns rubbish with a strong cross-shore again.

Sunday 30th morning is another gem: 10 feet, S swell, 13-second period, combined energy 3694, clean cross-offshore winds from the WSW. This is excellent for experienced surfers. The swell direction is a bit more south, which is fine for the bay.

Monday 31st morning: 7 feet, S swell, 12-second period, combined energy 1105, and glassy calm. This is a solid, clean, mid-size session for confident surfers. You’ll get some proper waves without the terror of the 10-foot plus days.

Tuesday 1st September morning rounds out the run: 6 feet from the SSW, 13-second period, combined energy 1252, and glassy. Another excellent morning for experienced surfers.

So, if you’re patient, the last week of August and first day of September deliver. The standout windows are Tuesday 25th morning for clean, small, long-period fun, and Saturday 29th and Sunday 30th mornings for the big, clean, powerful stuff. The rest of the time, it’s either flat, messy, or blown out. Keep an eye on those long-range forecasts, they’re promising but not set in stone.

Rusty.
