Mawi Surf Forecast and Surf Report

Alright, Rusty here. Let’s break down what’s cooking at Mawi for the next couple of weeks.

We’re looking at a solid stretch of south-west groundswell, but the wind is blowing from the south-east or south-south-east nearly every day, coming cross-off. That puts a bit of texture on the surface. The water temp is 80° today, which is pretty normal for this time of year.

The first real standout kicks off Tuesday, September 8th morning. Swell is 7 ft from the SSW with a 13-second period – proper groundswell. The combined energy is strong at 2803. The morning looks clean with a moderate breeze, but it’s cross-off, not offshore. This is a reef for advanced surfers only at this size.

That same Tuesday afternoon, the swell drops to 6 ft but the period stretches to a very long 18 seconds. Energy jumps to 3561. Those sets will have real punch and draw out nicely on the reef.

Wednesday, September 9th morning brings 8 ft SSW swell at 16 seconds, with energy at 3569. That’s big, powerful, and definitely expert territory. The afternoon is similar at 8 ft and 16 seconds, 3182 energy.

Sunday, September 13th morning has 7 ft SW swell with an 18-second period and energy at 3268. The wind eases to a gentle 9 mph from the SE – still cross-off, but lighter and cleaner. The afternoon bumps to 8 ft SW at 18 seconds, energy at 3681 – the biggest energy reading of the whole run.

Wednesday, September 16th morning is another one: 8 ft SW at 16 seconds, 3057 energy, cross-off wind at 16 mph. The afternoon holds 8 ft at 16 seconds, 3158 energy, with wind dropping to 12 mph.

The last real highlight is Sunday, September 20th afternoon. Swell is a smaller, cleaner 5 ft from the SW, but the period is a massive 21 seconds – the longest in the forecast. Combined energy is still strong at 2941. The wind is a gentle offshore from the SE at 9 mph, and the “excellent” surf conditions tag fits. This is your best bet for a smooth, manageable, long-wave session at the reef.

For the rest of the days, expect consistent chest- to head-high surf with cross-off wind. Crowds are possible here sometimes. Beginners should sit this whole run out – it’s too big most days and the reef is unforgiving. If you’re experienced and can pick your tide, the 8th, 9th, 13th, and especially the 20th of September afternoon are your go-tos.

Rusty.
