Mawi Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on the cards for us.

The big story here is a long, drawn-out run of solid, long-period SSW groundswell hitting Mawi, a reef break for advanced surfers only. It’s not a clean, easy wave for everyone, but for those with the skill, there’s plenty of energy to play with. The water temp is about average for the time of year, nothing weird there.

The action kicks off Monday, August 10th. We’ve got a 6ft SSW swell rolling in at a very long 19 seconds, pumping out a massive combined energy of 3992. The wind is a cross-off from the SE at 12 mph, keeping things clean. Monday afternoon sees that swell jump to a solid 10ft, with the same long 18-second period, and energy hitting 5622. That’s serious power. For an advanced surfer, this is the standout window early on. The wave is too big for beginners, but for the crew that can handle it, the conditions are clean.

Tuesday, August 11th, keeps the size up. Morning has 10ft at 17 seconds (energy 5386), a touch of cloud cover but still clean with the cross-off. Tuesday afternoon eases a touch to 8ft at 16 seconds (energy 4841), still clean. The drop-off is gradual.

Wednesday, August 12th, the swell backs down a bit. Morning is 6ft at 14 seconds (energy 2397), afternoon goes to 7ft at 16 seconds (energy 2109). The wind stays cross-off, but the quality is dropping. By Thursday and Friday, August 13th and 14th, we’re seeing 8ft to 8ft swells with periods of 16 to 17 seconds, and energy in the 2000s to 3000s. The comment on the data says “marginal surf forecast,” so the tide might be a factor. Still cross-off winds, but the juice isn’t as clean.

Now, the standout moment arrives on Saturday, August 15th, in the afternoon. The data flat-out says “excellent surf conditions for experienced surfers.” We’ve got a 8ft SSW swell at a long 17 seconds, combined energy of 3028, and a gentle 9 mph SE breeze. That’s as clean as it gets for this setup. For an advanced surfer, that Saturday afternoon session is the best bet on offer.

Sunday, August 16th, sees a slight drop to 7ft and 7ft, still long period at 16 seconds, but the energy is falling into the 1000s and 2000s. The wind stays cross-off, but it’s not as punchy.

The second week gets a bit grim. From Monday, August 17th, through to Tuesday, August 25th, the swell stays in the 4ft to 8ft range, with periods from 13 to 16 seconds, and energy mostly in the 1000s to 2000s. The wind picks up, becoming a fresh 19 to 22 mph cross-off from the SE. That’s a lot of wind. For a clean reef break, that’s rough. The data keeps calling it “marginal” or worse. The week of August 19th to 25th looks like a long stretch of poor quality.

The only real high note in the second week is the Saturday after the 15th, but after that, it’s a hard slog. The crowd situation at Mawi is “sometimes,” so on the good days, expect a few others in the lineup.

For the best of the best, point your board at Mawi on Saturday afternoon, August 15th. That’s the one. The rest of the week is for the dedicated, hardcore, and the very patient.

Rusty.
