Mangamaunu Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get stuck into what’s ahead for Mangamaunu.

This classic point break on the South-east coast is cooking up a real mixed bag over the next couple of weeks. Things start off small but clean, then build into some serious power that’s only for the brave, before fading back into smaller, cleaner conditions. The standout sessions are at the end of the month and into the first week of September. The water temp is about average for this time of year, so a standard 3/2 or 4/3 will do you fine.

You’ll be waking up on Wednesday, the 26th of August, to a cloudy sky and a light NNW wind. That’s cross-offshore, keeping the 3ft SSW swell (15 seconds) super clean. The wave energy is moderate (363). It’s not huge, but it’s a nice, long-period groundswell for a point break like this. The afternoon gets even better with a glassy NW breeze at 3 mph. The swell holds at 3ft, still clean.

Thursday, the 27th, the wind shifts to a cross-onshore NE breeze, ruining the 5ft to 6ft S swell. The early session is marginal and choppy, and the afternoon is a write-off with a strong 16 mph wind. Skip it.

Friday, the 28th, is a mess, too. The morning has a 6ft NE windswell with a short 7-second period and a cross-shore wind. It’s a chop-fest. The afternoon cleans up a bit, but the swell drops to 3ft. It’s barely worth the paddle.

The weekend is quiet. The 29th and 30th offer tiny 2ft to 3ft swell with light winds, but the energy is weak (less than 204). The Sunday morning even goes glassy, but it’s just too small.

Now, hang on to your board. Monday, the 31st of August is where it gets real. The morning kicks off with an 8ft S groundswell (12 seconds) and a shimmering cross-offshore WNW breeze. The energy is pumping at 1812. This is proper, powerful stuff for advanced surfers. It’s a standout. The afternoon is arguably even better: glassy calm, 8ft SSW swell, and the energy jumps to 2043. For a point break, that’s a dream. You’ll be paddling into some serious lines.

Tuesday, the 1st of September is the big one. Morning is glassy with an 12ft S swell (13 seconds) and a massive 4499 energy reading. This is heavy, expert-only territory. It’s a true standout session, but if you’re not on your A-game, stay on the beach. The afternoon drops to 8ft with a light cross-onshore wind, which might put a bit of a wrinkle on it.

The first week of September settles down. The 2nd and 3rd have clean, manageable 3ft to 5ft SSE swell with WNW cross-offshore winds. The 3rd afternoon is particularly nice, glassy with clean 3ft waves (539 energy). Good fun.

After the 4th, it gets small again. The 5th through the 9th offer tiny 1ft to 2ft swell from the SSE and S. There are some glassy mornings, like the 6th and the 8th, but it’s a slow period. The 7th has a bit more push with a 4ft S swell and clean conditions. The 9th and 10th are all small, clean, and glassy. The 10th of September morning is glassy with a 2ft S swell, and the 10th afternoon is glassy, too. It’s a classic end-of-season fade.

The clear winner here is Monday, the 31st of August, through Tuesday, the 1st of September. That’s the big, powerful, clean groundswell window. The 3rd of September afternoon is a solid second pick for a more relaxed session.

Rusty.
