Mangamaunu Surf Forecast and Surf Report

Right, listen up, crew. I'm Rusty, and this is your 16-day look at what's on the cards for Mangamaunu. This is a classic, advanced point break that needs a specific swell direction to really fire, and we've got a bit of a slow start before things get interesting. Let's get into it.

The first few days are a write-off for a surf. Sunday the 23rd is a total dud, with a tiny 1-foot swell and cross-off winds making it a waste of time. It's a quiet start, but don't let it fool you.

Monday the 24th is where it all kicks off. We're looking at a solid 7-foot S swell with a long 13-second period, cranking up the total wave energy to a very strong (1459). The wind is offshore from the WNW at 3 mph, which is perfect for a point break like this. It's clean, powerful, and for experienced surfers only. This is the standout of the whole forecast. The water is about 50°F, which is pretty normal for this time of year.

Tuesday the 25th drops back a bit, but still offers some fun. The morning has a 3-foot S swell (10-second period) with a gentle offshore WNW breeze, keeping it clean. The total energy is moderate (323). The afternoon sees a longer period wave from the S at 15 seconds, but it's smaller at 2 feet. Still, with the offshore wind holding, you'll get some long, racy lines.

Wednesday the 26th is all about the glass. The wind goes to nothing, N at 3 mph, and we have a clean 2-foot to 3-foot SSW/S swell. The period is a long 14 seconds, meaning the energy is moderate (291). It's not big, but it's a beautiful, clean day for a cruise on a longboard. The total wave energy is moderate (291).

Thursday the 27th is a tale of two halves. The morning is a bit messy with a cross-shore S wind and a 4-foot S swell, but the afternoon saves it completely. The wind switches to glassy ENE at 3 mph, and that same 4-foot S swell has a very long 16-second period. The energy is strong (1012), and the conditions are excellent for experienced surfers. This is another top pick.

Friday the 28th is a mixed bag. The morning has rain and a cross-shore N wind on a 4-foot S swell, which is a bit ordinary. The afternoon, however, turns glassy with a SE wind and a clean 3-foot S swell. Not a standout, but a solid session.

The first weekend of the forecast, Saturday the 29th and Sunday the 30th, sees a drop in size. The swell fades to 2-foot to 3-foot with mostly clean conditions, but the energy is weak (172). It's a bit of a lull, but manageable for a small-wave board.

Now, a big shift on Monday the 31st of August. A new 8-foot to 8-foot S swell arrives, pushing the total wave energy to very strong (1986). The wind is a cross-offshore SW, so it's clean, but this is a big wave. At 8 feet, this is strictly for experts. The period is a moderate 10 to 13 seconds, so it's more of a powerful, lumpy swell than a long-period groundswell.

Tuesday the 1st of September brings a drop back to 5 feet with glassy conditions, offering a fantastic, clean window for those who want a big but manageable wave. The energy is strong (660).

After that, the surf gets smaller and inconsistent for a few days, with the 2nd to the 4th of September offering only small, clean waves, but the energy is weak (149). The 5th is a dud.

Then, hold onto your board. On Sunday the 6th of September, the forecast shows a massive 13-foot S swell. The total wave energy is off the charts, reading 4196. The wind is a light cross-off from the NW, and it's clean. But for a point break like this, 13 feet is too big. This is a monster, and it's dangerous. Even for experts, it's a serious call. The following Monday the 7th still has a very solid 10-foot to 8-foot swell with clean to cross-off winds, which is still a big, expert-only session.

So, the two true standouts are Monday the 24th and Thursday the 27th afternoon. Get in the water. The big swell on the 6th is a spectacle, but not a day for a paddle.

Rusty.
