Mawi Surf Forecast and Surf Report

Alright, Rusty here. Let’s check the waves.

We’ve got a solid run of swell coming in for Mawi, but it ain’t all sunshine and barrels. The whole 16-day window is active, but most of it is for the experienced crew. Water temp is sitting around 79°, which is pretty normal for this time of year.

The first action kicks off Wednesday afternoon, September 9th. We’re looking at an 8ft SSW groundswell with a very long 16-second period from the southwest. That’s a ton of energy – the combined energy is pumping at 3182 – but the wind is a cross-off from the SSE at 12 mph. It’s clean, but not glassy. For a reef break exposed to SW swell, this is a solid start. This is advanced territory; 8ft is getting up there.

Thursday the 10th and Friday the 11th keep the swell coming, mainly in the 6ft to 7ft range, still with that long-period SSW to SW pulse. Winds stay cross-off, keeping things clean, but the conditions are a bit touchy. Same story for Saturday the 12th: 5ft to 5ft SW swell with a 14-second period, winds drop to a gentle breeze. It’s cleaner, but the energy is still moderate.

Sunday the 13th is interesting. The morning shows a 6ft SW groundswell with an 18-second period – that’s a very long period. The combined energy jumps to 2792. On a reef like Mawi, that could be beautiful, but those long intervals mean you’ll be waiting between sets. Still, it’s clean with cross-off winds.

Now, the real standout is Friday the 18th and Saturday the 19th. On Friday morning, we’ve got a 5ft SW swell with a 16-second period, and the wind drops to a light breeze from the SSE at just 6 mph. That’s about as clean as it gets. The comment calls it excellent for experienced surfers. Saturday morning the 19th is similar: 5ft SW swell, 14-second period, and again just a light breeze. Glassy conditions.

The other big highlight is Sunday the 20th and Monday the 21st. Sunday morning sees a 8ft SW groundswell with a 16-second period – combined energy at 2966 – and light winds. That’s big, powerful, and clean. Sunday afternoon bumps to 8ft. Monday morning is 8ft. This is expert territory, but it’s going to be pumping. Crowds at Mawi are just “sometimes,” so you might have some company but not a circus.

After Monday the 21st, the swell backs off but stays active. Then another pulse shows up on Wednesday the 23rd with 7ft to 8ft SSW swell, and by Thursday the 24th we’re back to 8ft SSW swell with a 17-second period and combined energy of 3937 – the biggest energy reading of the whole run. That’s deep in the forecast though, so take it as promising but not locked in.

All in all, Mawi is the only break on offer, and it handles SW swell best. The whole period is consistent with long-period groundswell, which means better shape and more energy, but also long lulls. For the advanced crowd, the standouts are Friday the 18th/Saturday the 19th for clean, moderate-sized perfection, and Sunday the 20th through Monday the 21st for bigger, powerful surf. That last pulse on the 24th is a wildcard for the brave.

Rusty out.
