Mawi Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what we’ve got coming up at Mawi.

This is a solid run of surf stretching right across the next 16 days, with no real gaps in the action. It’s an advanced reef break that’s fairly consistent and exposed to the southwest swell, meaning it catches a lot of what the ocean throws at it. The water temp is sittin’ right around 79°, which is bang on average for this time of year, so no surprises when you splash in.

We start off Tuesday the 25th and Wednesday the 26th with some clean, cross-off conditions from the southeast, but the surf is a bit ropy. Swell is around 6 ft from the SSW with a moderate combined energy (1291 to 1049). The period is 14 to 16 seconds, so there’s some push, but the quality is marginal, and the score reflects it. It’s surfable for the experienced crew, but nothing to rush for.

Thursday the 27th sees the swell drop back to 3 ft to 4 ft, but check this out – the period jumps to a very long 20 seconds under a gentle cross-off breeze. The combined energy actually spikes to 1815, which is moderate but punchy for the size. That’s a proper groundswell pulse. It’ll be clean, but that long period at a reef like Mawi means the waves will have real shape and power between sets. The paddle out will be easier between the lulls.

Now, the real standout. Friday the 28th of August. We get a pumping 10 ft SSW swell (8 ft in the arvo) with a 16-second period. The combined energy jumps into the strong zone at 4302, so you’re gonna feel that in your chest. Winds stay cross-off and light enough to keep it clean. This is big, powerful swell at an exposed reef – experts only territory. No beginners here. This is the pick of the 16-day window by a decent margin. The water will be churning, and the sets will be lined up and heavy.

Saturday the 29th is very good too, especially the morning. The swell drops to a still-chunky 7 ft, period 15 seconds, with gentle cross-off winds. The comment says “excellent surf conditions for experienced surfers” – I’d back that up. Combined energy at 1885 is strong enough to give you plenty of push. That Friday and Saturday morning combo is the heart of this forecast.

Sunday the 30th through Monday the 31st is still clean but the swell backs off a touch to the 5 ft to 6 ft range. The period on Monday morning spikes again to 19 seconds, which is very long, so expect clean, powerful lines with longer waits between sets. The combined energy (1614 to 2133) keeps it interesting.

Heading into September, Tuesday the 1st and Wednesday the 2nd see the swell holding steady around 7 ft from the southwest, period 16-17 seconds. Combined energy stays in the moderate-to-strong bracket (2166 to 2478). Winds are a consistent moderate cross-off breeze. It’s solid, consistent, and clean, but the scoring suggests the tide or some other factor keeps it from being epic.

From Thursday the 3rd of September onward, the swell gradually fades. We go from 6 ft down to 4 ft by Friday the 4th, with the combined energy dropping below 1000. The wind stays cross-off, and the wave state remains clean, but you’re into smaller, less powerful surf. Still worth a paddle if you’re keen on a mellow session.

Things perk up again on Sunday the 6th of September. The swell jumps back to 8 ft from the SSW, period 15 seconds, combined energy at 2910. The afternoon session on Sunday is rated higher, with a 4 out of 10 and a clean outlook. Monday the 7th holds onto that 8 ft range. Then Tuesday the 8th and Wednesday the 9th see it taper off again, with the swell dropping to 5 ft to 6 ft, but still clean and rideable.

So to sum up: The absolute best on offer is Friday the 28th of August, with that 10 ft SW groundswell and clean cross-off winds. Saturday morning the 29th is a close second. After that, there’s a solid run of 6 ft-plus days right up to Monday the 7th of September that will keep the stoke alive. It’s a classic exposed reef run with plenty of long-period groundswell.

Keep your wits about you when it’s over 8 ft – this is not a forgiving break when it’s big. That Friday is for the chargers only.

Stay salty,
Rusty
