Mawi Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. The only wave on the menu for the next 16 days is Mawi, a solid reef break. This is a big, powerful setup, and it’s not messing around. We’ve got a serious run of groundswell coming in, so if you’re an advanced surfer, your ears should be perked up.

The pattern starts on Monday, August 10th, and it’s not a gentle start. We’re looking at a massive 10ft swell from the SSW, with a very long period of 18 seconds. That’s a ton of energy – the combined energy reading is a massive 5622, which is seriously strong. The water temp is sitting at 80°, which is bang on average for this time of year, so no surprises there. The wind is a cross-off from the SE at 12 mph, keeping the surface clean. This is a big, powerful, groundswell, and that long period means it’s going to be sucking up and throwing down on the reef. Not a beginner wave by any stretch.

Tuesday, August 11th, keeps the party going. Morning still has 10ft SSW swell with a 17-second period, energy still huge at 5386. The wind is a clean cross-off again. It’s a bit of a grind, but for the right crew, this is pure magic. The afternoon sees it drop slightly to 8ft, but still packing a punch.

The swell hangs around the 7ft to 8ft range for the rest of that first week, always with solid SSW direction and long periods, mostly 16-17 seconds. The wind stays cross-off, keeping the surface clean. It’s a constant, high-energy stretch. Thursday the 13th has a solid 8ft at 17 seconds, with energy at 3642 in the morning.

Now, the standout for the whole run is the morning of Tuesday, August 18th. The swell drops to 6ft, but it’s a clean 16-second SSW groundswell, and the combined energy is still a moderate 1965. The wind is a gentle breeze from the SE, making for glassy, clean conditions. This is the sweet spot. The guidance notes this as excellent for experienced surfers, and I’d agree. It’s the best balance of power and manageability. The crowds are listed as “sometimes,” so you might have some company, but it’s worth it.

The second week gets a bit more interesting. Wednesday, August 19th, sees the swell bump up to 7ft from the SW, and that trend continues. Then Thursday, August 20th, we get another big pulse: 10ft from the SW, with a 16-second period and energy at 4297. That’s a lot of water moving. The wind is a cross-off, but it’s a fresher breeze at 19 mph, so it’ll be a bit bumpier. Definitely an expert-only window.

The run continues with solid 7ft+ SW swell right through the 22nd. Then, a real wildcard shows up on Sunday, August 23rd. The swell drops to just 4ft, but the period stretches out to a massive 21 seconds. That’s a very long period groundswell, and the energy is still a solid 2748. This kind of swell can be weird on a reef – it might break too straight, or it might just pulse with perfect, peaky waves. The wind is light and clean. Worth a look for the early crew.

Finally, Monday, August 24th, we get another 10ft SSW pulse, 17 seconds, with energy at 4606. The wind is light again, so it’ll be clean, but you better know what you’re doing.

So, to sum it up: Mawi is on fire, but it’s a heavy wave. The best bet for the most fun is the morning of Tuesday, August 18th, with that clean, shoulder-high, groundswell. The big, dangerous stuff is on the 10th, 11th, 20th, and 24th for the experts only. Stay safe out there.

Rusty.
