Kandui Left Surf Forecast and Surf Report

Alright, surfers, Rusty here. Let’s get into it. We’ve got a solid stretch of waves on the horizon, but it’s not all gonna be easy. There are some proper standouts to keep an eye on, along with a few days in the middle where you might want to sleep in.

We kick things off on Friday, August 7th, at Kandui Left (Mentawai Islands). The water is a warm 85°F, which is right about normal for this time of year. Swell is coming in at a healthy 8ft with a long 18-second period, and there’s a nice cross-off breeze from the north at 9 mph. That’s a recipe for some real classic reef-break lines. The energy is strong, with the combined swell energy reading 3564. It’s not perfect everywhere, but there are some excellent waves for the experienced crew out there.

Saturday, August 8th, builds on that. Swell drops slightly to 8ft but the period remains a solid 16 seconds. The N wind is gone, replaced by a light 3 mph SE offshore breeze in the morning, which is even better for clean surfaces. Saturday afternoon looks absolutely glassy, with 3 mph SE winds and a distinct lack of any wind chop. This is one of the best windows on offer. This is the one I’d be circling.

We’ve got a bit of a lull from Sunday, August 9th, to Wednesday, August 12th. The swell sticks around the 6ft to 8ft range, but the wind turns cross and cross-on, with increasing strength. It’ll be lumpy and not the cleanest by any stretch. The energy remains moderate, but quality is just not there. The combined energy is in the 2,000 to 3,000 range - all that juice with nowhere civilized to go. You might get a couple, but it’ll be a fight.

Things pick up again on Thursday, August 13th. The swell gets a little more organised, with a period stretching out to 19 seconds. Still a bit of cross-shore chop, but you can feel it building.

Then, on Friday, August 14th, the swell jumps up to a full 10ft. That’s a big, powerful SSW groundswell with a 16-second period. The energy reading jumps to 3970. This is one for the experts, and even then, it's heavy. The wind is light from the SSE at 6 mph, which helps, but with 10ft on the reef at Kandui Left, you need to know what you’re doing. This is the start of the bigger stuff.

Saturday, August 15th, brings a brief moment of calm with a 7ft swell and morning glass. A tiny window where you can get it clean again before the next pulse. Energy has dropped a bit, sitting around 2063, so it’s not as powerful, but it’s much more manageable.

Sunday, August 16th, sees the swell fade a bit more to 5ft, but the wind turns cross-off from the ESE, which should keep the lines pretty clean. Not the big stuff, but a fun, rippable size.

Monday, August 17th, is a bit of a letdown. The swell drops to 5ft and the energy falls away. The morning might be okay, but the afternoon looks poor and choppy with a cross-on wind. I’d take that day off.

Now, here’s where it gets interesting. We’ve got a long-range pulse arriving in the second week. The standout for the whole run is Thursday, August 20th. The forecast shows a solid 12ft SSW swell with a strong 17-second period. The combined energy reading is a massive 7109, the biggest we see by a long shot. Winds are moderate and cross-shore from the SE, but with that size and period, it’s gonna be a heavy, powerful day. This one is for the hardcore guys only, and it’s still a week and a half out, so you’ve got time to plan. There’s also a push on the morning of Tuesday, August 19th with 10ft swell, which looks okay, but the 20th has the size and the energy.

After that big day, the swell slowly backs down through Friday and Saturday the 21st and 22nd, getting smaller and less consistent, with the wind turning more onshore and messing things up. By Saturday afternoon, it’s looking pretty average and the fun is over.

So to sum it up: grab the morning of Saturday the 8th for sure. Then keep Saturday the 15th and Sunday the 16th in your back pocket for something a bit more relaxed. And if you’re a serious charger, circle the 20th of August. It’s a long way out, but it's got all the makings of a proper session.

Rusty, out.
