Mangamaunu Surf Forecast and Surf Report

Alright, this is Rusty. Let's get into it.

The first few days are a bit of a waiting game, but once the wind and swell line up, this spot really fires. The main event is a solid, long-period South swell that pushes through the middle of the window, and we’ve got a couple of real standout sessions.

We start off Monday, July 20th with a bit of a tease. The swell is a solid 7ft from the South, running on a very long 18-second period, which gives it some serious grunt. The combined wave energy is a massive 3140, so it’s a powerful groundswell. But the wind is from the East, putting it onshore, and the report calls it marginal. It’s a big, lumpy setup for now.

Things change fast. Tuesday morning, July 21st is where it starts to get interesting. The swell drops to 5ft from the South, but the period is still a solid 14 seconds. The wind swings to the West, giving us clean offshore conditions. The energy is a moderate 923. This is a really good wave, but it’s going to be for advanced surfers only. The crowd is rare here, so you’ll have plenty of room.

Tuesday afternoon is a dream. The swell settles to 5ft from the South, period at 13 seconds, and the wind goes completely flat. Glassy. The energy is 733. Conditions are described as "very good," and for a point break like Mangamaunu, that’s as good as it gets. This is the best of the first week.

The next few days drop off quickly. Wednesday, July 22nd sees the swell drop to 3ft, and by Thursday, we’re down to knee-high dribble. The wind is good, but there’s no push. There’s a long gap of poor to no surf from the 23rd through the 25th. On Saturday, July 25th, the wind is howling from the WSW at 19 mph, and while there’s a 5ft swell, it’s short-period slop. Not worth it.

The second week brings a new pulse. Monday, July 27th is a real standout. The morning shows a 4ft swell from the East with a 15-second period, clean with a cross-offshore wind and an energy of 799. The afternoon gets even better: 5ft from the ESE, 13-second period, light wind, and an energy of 1042. The report calls it "excellent for experienced surfers." This is the best of the second week, but it’s a long-range call, so it’s promising but not guaranteed.

Tuesday, July 28th is a bit messy with cross-on winds, but the swell is similar. Then Wednesday, July 29th cleans up again with a 4ft ESE swell and light offshore winds. The energy is 588.

There’s another small window at the very end. Sunday, August 2nd is a big one. The morning brings a 10ft swell from the South, period of 10 seconds, and glassy conditions. The energy is a massive 2059. That is a big wave. It’s for experts only, and it’s at the very end of the forecast, so treat it with caution. The period is short, so it might be a bit lumpy, but on a point break, it could still be a beast.

The water temperature is 53°F with a slight anomaly of 1°F warmer, so it’s about average for this time of year at Mangamaunu. Bring a good suit.

The standout sessions are Tuesday afternoon, July 21st for the glassy, clean perfection, and Monday afternoon, July 27th for the punchy, longer-period swell. The big one on August 2nd is a promise for the brave.

Rusty.
