Mangamaunu Surf Forecast and Surf Report

Alright, let's break down what's coming for the next couple of weeks. The only wave in town is Mangamaunu, a serious point break for the advanced crew. It's a very consistent spot, open to the ocean, and it loves a south-east swell. The water temp is about 51°F, which is normal for this time of year.

The action starts on Friday the 11th of September. Friday morning is small, with a 2ft south swell running at a very long 18 seconds. The wind is glassy, dead calm out of the north-west, so the waves will be clean, but it's tiny and the energy is weak. A quiet start.

Saturday the 12th is the big standout. Saturday morning you've got a solid 6ft south swell with a long 16 second period, and the combined energy is pumping strong. The wind is dead calm, glassy conditions – perfect for that exposed point. This is excellent surf for experienced surfers. As the day goes on, the swell builds to 8ft in the afternoon with 15 second period, and the energy gets even bigger. The wind switches to light and onshore though, so the morning session is the clear winner. Go early.

Sunday the 13th drops back a touch, with a 6ft south swell at 13 seconds. Morning wind is light and cross, so it's not as clean as Saturday. The energy is still decent, but it's a step down.

We've got a lull mid-week. Monday the 14th is smaller, around 4ft to 5ft, with glassy winds in the afternoon, but the energy is fading fast. Tuesday the 15th is tiny, 2ft to 2ft, and by Wednesday the 16th the swell is barely there, with poor conditions and onshore wind. There's a real gap here for several days with nothing worth paddling out for.

The next flicker of hope comes Saturday the 19th of September. Saturday morning sees a 6ft swell, but it's from the north with a short 6 second period. The energy is moderate, and the wind is light and cross-off, so it will be clean. It's a short-period windswell though, not the deep groundswell of the previous week.

Sunday the 20th looks big but messy. You've got an 8ft south swell, but the period is short at 9 seconds, and the wind is a fresh 22 mph cross-off. The energy is high, but for a point break, a big short-period swell with strong wind just makes for a choppy, hard-to-manage session. This one is for the big dogs.

After that, Monday the 21st brings a clean 5ft south-east swell with glassy conditions in the morning, but the energy is dropping. The rest of the week fades out to tiny, poor surf. There's a small pulse on Friday the 25th with a 2ft south swell at a long 17 seconds, with glassy wind, but the energy is low.

So, to sum it up: Saturday the 12th of September is your day. The morning glass-off with that solid 6ft south groundswell and very long period is the absolute pick of the bunch. Get on it before the wind turns. The following Saturday the 19th is a distant second option with a clean but short-period windswell. Otherwise, it's a lot of waiting around.
