Suruga Bay Surf Forecast and Surf Report

Alright folks, Rusty here with a look at the surf ahead for Suruga Bay. Gotta be straight with you—this is a classic tale of two halves. The next week and a half is pretty flat and messy, but if you can wait, there’s a serious pulse of energy lining up for the final weekend and into the next week. Hold tight.

The first real action worth paddling out for is on Tuesday morning, September 8th. We’ve got a clean 5ft south swell rolling in with a 9-second period, producing moderate wave energy (443). The wind is glassy out of the east at just 3 mph, so conditions will be smooth. The water temp is sitting at 81°, which is pretty much bang on average for this time of year, so don’t stress about a wetsuit. This is the only real highlight for days, and it’s a short window.

After that, things fall apart quickly. From Tuesday afternoon right through to Saturday, September 19th, it’s a long, grim stretch of weak, wind-affected waves. Swell drops below 3ft, periods get short and periods of onshore and cross-shore winds dominate, leaving the bay choppy and uninviting. There’s a run of ten days where you’re better off doing something else.

But then everything changes. Sunday, September 20th kicks off a proper late-season groundswell event. Sunday morning brings glassy conditions with a 3ft swell, but don’t let the size fool you—the period is a massive 21 seconds, and the energy is strong (843). By Monday, September 21st, it gets serious. The swell jumps to 7ft out of the southeast with an 18-second period, absolutely cranking (3384 energy). The wind is light cross-offshore in the morning and glassy calm by Monday afternoon. This is excellent, powerful surf, but at over 8ft combined with that long period, this is strictly for experienced surfers—this break will be thumping. The deep water groundswell will unload with authority. Expect a crowd, as this spot does get busy when it’s on. This is the true standout of the whole outlook.

Tuesday, September 22nd hangs in there with a solid 6ft swell and glassy conditions in the morning from the west. Still plenty of grunt (1808 energy) and a long 16-second period for more great waves, but again, that size is in the expert zone.

That’s the window. By Wednesday, September 23rd, it fades back into small, wind-blown junk. So, if you’re in Suruga Bay, save your energy for that September 20th to 22nd window—the Monday the 21st is the day to circle on the calendar.

Stay sharp, keep an eye on the sky.
Rusty.
