Shichirigahama Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s on the menu for Shichirigahama over the next couple of weeks. It’s a bit of a slow burn, so don’t be in a rush.

We kick off this Sunday morning, August 2nd, with a tiny, clean little wave. The water is sitting at a warm 82°, which is a touch warmer than normal for this time of year. A small 1ft groundswell out of the ESE with a very long 16-second period is pushing in, but it’s weak, with combined energy of just 107. The wind is a light cross-off, making it look clean, but it’s honestly more of a paddle-around session than anything to get excited about. The afternoon goes onshore and messy, so forget it.

Monday, August 3rd, we see a slight bump. The swell sticks to 2ft to 3ft from the SE, period still a lovely 16 seconds. The morning is a bit tricky with that 19 mph offshore, but the afternoon settles into a cleaner, moderate offshore. The energy is climbing into the moderate range (around 277 to 449), but it’s still small. It’s marginal, but the cleanest of the small stuff.

Now, Tuesday morning, August 4th, brings a more noticeable jump. Swell hits 5ft from the SE, period 16 seconds, and the wave energy is strong at 1059. Offshore wind is fresh and clean. This is the start of the build. It’s not quite a standout, but it’s getting there.

The real action kicks off on Wednesday, August 5th, and runs through to Saturday, August 8th. This is the window. Wednesday morning sees 8ft from the SSE with a fresh offshore, and the energy is pumping at 3499. By the afternoon, it’s up to 10ft. That’s big, expert territory. Thursday, August 6th, is the absolute peak: 10ft of solid S swell, period 16 seconds, and the energy is massive at 4406. The morning is a clean offshore, and the afternoon is a cross-off with a gentle breeze – this is the best on offer. The water is still warm, and while the waves are going to be strong and powerful, the conditions are excellent for experienced surfers. Friday, August 7th, drops a touch to 8ft, still clean with a cross-off, but the energy is backing off. Saturday, August 8th, is a solid 7ft from the SSW with a moderate offshore in the morning, making it another good option for those who know what they’re doing.

After that, the swell fades fast. From Sunday, August 9th, onward, the size drops back to 5ft and smaller, and the conditions become increasingly marginal or poor. The wind stays clean but the energy drops out. From Tuesday, August 11th, through to the end of the run on August 17th, it’s a real lull with weak, small waves and mostly poor conditions. The wind is often strong offshore, but with the swell so tiny, it’s just a clean, flat lineup.

So, the standout is the run from Wednesday, August 5th, through to Saturday, August 8th. Thursday, August 6th, is the peak. That’s 10ft of S groundswell, combined energy of 4406, and a clean cross-off breeze. It’s a powerful, deep-water swell that will be breaking straight at a river-mouth break, so expect it to be a bit shifty and heavy. This is only for the experienced.

Rusty.
