Shichirigahama Surf Forecast and Surf Report

Alright, this is Rusty. Let's have a look at the surf forecast for Shichigahama, specifically Shichirigahama, a river mouth setup.

The next week and a half is a real mixed bag. We're looking at a solid build-up of swell, but it's going to take a few days to get going. The water temp is sitting at 82°, which is a touch warmer than usual for this time of year, so you can leave the thick wetsuit at home for now.

Saturday the 1st and Sunday the 2nd are pretty much flat. You'll see some tiny 1ft to 2ft waves, but the energy is weak (22 to 132), and the conditions are just ordinary. Not worth paddling out for.

Things start to get interesting on Monday the 3rd. The wind swings offshore from the NNE, cleaning things up. The swell builds a bit, and by the afternoon we've got 3ft waves from the ESE with a long 16-second period. The combined energy jumps to 476 (moderate). It's not huge, but it's the first sign of life.

Now, Tuesday the 4th is where it starts to get real. The morning sees 5ft of SE swell with a 17-second period, and a fresh NNE offshore wind. The energy is strong (1137). This is a proper groundswell. The afternoon pushes up to 6ft, but the wind goes cross-offshore, so the morning session is the cleaner bet.

The standout window is Wednesday the 5th through to Saturday the 8th. Wednesday morning is already pumping with 8ft from the SSE, but the afternoon is the real hero. We're talking 10ft of SSE swell, 16-second period, with a moderate NNE offshore wind. The wave energy is very strong (4006). This is excellent, powerful surf, but it's strictly for experienced surfers only. This is a big, powerful river mouth wave.

Thursday the 6th keeps the size with 10ft from the S, but the morning is the call with a moderate offshore wind. The energy is 4457. The afternoon gets a bit of a cross-shore wind, making it more marginal. Friday the 7th still has 8ft to 8ft of S swell, but the wind is all over the place, mostly cross or cross-off. It's still surfable, but not as clean.

Saturday the 8th is the last day of proper size, with 6ft of SSW swell and a clean offshore wind in the morning. The energy is still strong (1379). It's a good option for a last hurrah before the swell drops.

After the 8th, the swell fades fast. From Sunday the 9th onward, we're back to small, weak waves, mostly under 3ft, with moderate to fresh winds. The energy drops to weak (273 and below). There are a few glimmers of glassy conditions on the 14th, but with only 2ft on offer, it's not going to be worth the effort.

So, for the best of it, you're looking at the Wednesday 5th through Saturday 8th window. The absolute standout is the afternoon of the 5th and the morning of the 6th for the biggest, cleanest, most powerful surf. If you're not an expert, steer clear of the 8ft+ days. And remember, this is a river mouth, so long-period groundswells like this can sometimes break a bit straight, but with the offshore wind, it should still be fun.
