Shichirigahama Surf Forecast and Surf Report

Alright folks, Rusty here, let’s have a look at what’s cooking for Shichigahama over the next couple of weeks. It’s a bit of a slow burner, but we’ve got a proper window of quality groundswell if you play your cards right.

First up, the water temp is sitting at 74°, which is about 1° cooler than the norm for this time of year. Nothing to get weird about, just a touch of that early summer chill.

Right, the start of the period is flat and messy. Sunday the 5th and Monday the 6th are a write-off – weak, short-period slop with onshore wind. It’s all poor surf conditions. Just forget about it and do something else.

Things start to look alive on Tuesday 7th July. By morning we’ve got an offshore breeze from the NNE at 12 mph and a clean 2 ft swell from the SSE with a solid 15-second period. The combined energy is moderate (466). It’s small, but clean. Then by the afternoon, it builds to 4 ft from the SE with 15 seconds and a cross-offshore wind (763 energy). It’s gonna be smooth and getting more push. A good day to ease in.

Wednesday 8th July is where it really wakes up. Morning brings 5 ft from the SSE with a long 17-second groundswell. The wind is a light cross-off at 9 mph and the energy jumps to a strong 1605. This is excellent for experienced surfers – proper groundswell lines, clean faces. The afternoon has the same size but the wind swings onshore from the SSW, so grab the morning session.

Now, Thursday 9th July morning – this is a standout. It’s glassy, dead calm (3 mph from the east), with 5 ft of 15-second S swell. The energy is very strong at 1496. The water will be like a mirror. This is prime, clean, powerful surf. For the experienced crew, this is your pick. The afternoon gets onshore again, so don’t sleep in.

Friday 10th July morning is even bigger – 7 ft from the S with a 17-second period and a massive 2339 energy. It is glassy again (3 mph from the SSE). That is strong, long-period energy hitting an exposed river mouth. It’ll be pushing, powerful, and it’s only for experienced surfers. It could be a bit dicey if the river mouth lines up wrong with that long period, but the conditions are perfect. Afternoon gets onshore and lumpy, so all eyes on the morning.

Saturday 11th July morning still has size (7 ft, 17 seconds, 2574 energy) but the wind is onshore from the south. It’s not the clean window the day before. Afternoon turns into a fresh cross-onshore mess.

From Sunday 12th through to the end of the period, it drops off fast. There are scattered days with 3 ft to 4 ft of short-period, onshore wind swell. It’s a long stretch of poor to marginal conditions. The 18th of July has a brief moment with 3 ft from the S but it’s onshore. Not worth stressing over.

So the bottom line: the window is Wednesday 8th July through Friday 10th July mornings. Friday 10th is the standout for the real size and power (7 ft, 17-second S swell, glassy conditions) but it’s for experts. Thursday 9th is the sweet spot for high-quality clean waves at 5 ft with no wind. Don’t expect much else for two weeks after that.

Rusty.
