Mangamaunu Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got Mangamaunu on the menu for the next couple of weeks, and it’s a bit of a mixed bag but with some absolute crackers in the mix.

The overall pattern starts nice, fades away for a bit, then comes roaring back with some serious power. The first few days are the clear standouts before we hit a lull, and then the second week ramps up into proper, heavy, expert-only territory.

Tuesday, July 21st is where you want to be. Morning kicks off with clear skies, a light offshore wind from the West, and a solid 5ft south swell pumping in with a long 14-second period. The combined energy is strong at 923, and it’s going to be clean as a whistle. By the afternoon, the wind drops to a dead glassy calm, the swell is still 5ft, and it’s just pure, lined-up perfection. This is the best of the whole run. The water temp is about average for the time of year, so a 3/2mm should be fine.

Wednesday, July 22nd is still good but smaller. A 3ft south swell with a cross-offshore wind in the morning keeps things clean. The energy drops to 223, so it’s a bit more relaxed. Afternoon gets a bit messy with a cross-onshore wind though.

Thursday, July 23rd through Friday, July 24th is a quiet period. Swell drops right off. The energy falls to two-digit numbers, barely a ripple. You'd be struggling to get wet.

Saturday, July 25th gets interesting for the wrong reasons. The morning is blown out by an 18 mph wind, but the afternoon sees a jump in size to 8ft from the SSW. The problem is the period is short at 7 seconds, and it’s still cross-offshore with a fresh breeze, making it lumpy. The energy is moderate at 765 but it’s not clean.

Sunday, July 26th shows some promise again. A 3ft swell from the ESE with a very long 14-second period and a cross-offshore wind. The energy is 521, and the waves will have good shape, but it's not huge.

Monday, July 27th is another standout. The morning has a 4ft easterly swell with a 15-second period, very long period groundswell, and clean cross-offshore winds. The energy is 1028, moving into strong territory. The afternoon is even better: 6ft, glassy, and a 13-second period. The energy jumps to 1387. This is excellent, powerful surf. It’s getting into the size where it’s for the more experienced crew, but the conditions are pristine.

Tuesday, July 28th and Wednesday, July 29th see a bump in size but a drop in quality. We’re looking at 7ft and 6ft swells, but the winds turn cross-shore and cross-onshore, putting a bit of chop on the face. The energy is high (1635 and 893), but the conditions are only marginal.

Thursday, July 30th cleans up again. Morning brings a 5ft ESE swell, long 13-second period, and a light cross-offshore wind. Energy is 883, and it’s clean. This is a good session.

Friday, July 31st starts clean with a smaller 4ft ESE swell, but the afternoon gets blown out again by a 15 mph southerly.

Saturday, August 1st is a wild card. The morning is glassy, with a 7ft SSW swell but a short 8-second period. The energy is 905. The afternoon jumps to 8ft, which is big and pushing into expert-only territory, with a light cross-onshore wind.

Sunday, August 2nd is firing. The morning is glassy, with a 6ft south swell carrying a 14-second period. The energy is 1248. This is excellent, powerful surf for experienced surfers. The afternoon gets bigger at 8ft, but the wind turns onshore.

Now, Monday, August 3rd through Wednesday, August 5th, things get serious. The swell really cranks up. We’re talking 16ft on Monday morning with a 14-second period and a combined energy of 8397. That is massive. The wind is light, but the swell is way too big for this break. It’s a warning in the data: the break can’t handle this size. This is for the absolute elite, and even then, probably not. It settles to 12ft on Wednesday, but still a huge 15-second period and 5503 energy. The wind is cross-shore, making it tricky on top of the size. This is not a paddle-in session for anyone but the most experienced heavy-water surfers.

So, to wrap it up: the best all-round session is Tuesday, July 21st – clean, lined-up, and fun. The second best is Monday, July 27th for those who want a bit more power. After that, it’s a waiting game with a few good windows, but the end of the run is for the big-wave chargers only.

Rusty out.
