Mangamaunu Surf Forecast and Surf Report

Yo, it's Rusty. Let's dive into the Mangamaunu outlook. We've got a solid run of surf ahead, but it's a bit of a mixed bag, so you gotta pick your windows.

The overall pattern is a slow start that builds into some real quality, especially towards the end of the first week and into the second. The water is sitting at 50°, which is a touch cooler than average for this time of year, but nothing crazy.

First up, the standout is Saturday morning, August 8th. We have a clean 4ft swell from the S with a solid 11-second period, generating a decent 498 (moderate) combined energy. The wind is a glassy 5 km/h from the WNW, so it's gonna be absolutely clean at the point. The wave comment says "expect good surf conditions," and with Mangamaunu being a very consistent point break that handles swell well, this is your best early bet. It's an advanced wave, so keep that in mind.

That afternoon, the wind shifts and the quality drops. Saturday is your pick.

Sunday morning, August 9th is also clean with offshore WNW winds at 5 km/h, but the swell drops to 3ft from the SSE. It's small but clean, a good option for a longboard or a cruiser.

Monday through Tuesday sees a bit of a lull with messy winds and very ordinary conditions. The swell is small and the wind is cross-off or cross-on, making it less appealing. The combined energy drops to 148 (weak) on Monday morning.

Wednesday morning, August 12th brings a tiny 3ft swell from the E with a 6-second period and light cross-off wind. The combined energy is only 158 (weak). It's surfable, but it's not going to get your heart racing.

Friday morning, August 14th is a nice return to form. We have a 4ft swell from the ENE with a 9-second period, giving us 359 (moderate) combined energy. The wind is light and cross-off from the NW at 5 km/h, keeping it clean. The wave comment confirms "expect good surf conditions."

Saturday morning, August 15th is another good one. A 4ft E swell with a 10-second period, 324 (moderate) combined energy, and light cross-off wind from the SSW. Clean again.

Now, check this out. Sunday morning, August 16th is a weird one. The swell is only 2ft, but the period is a massive 18 seconds from the S. That's a very long period groundswell, and the combined energy is 300 (moderate). It's gonna be a super clean, glassy morning with SSE wind at 5 km/h. Because the period is so long, this kind of swell can be a bit too straight for a beach break, but at a point break like Mangamaunu, it could be super fun, long walls. Keep an eye on the tide.

Monday morning, August 17th is your next chance for something bigger. A 5ft swell from the S with an 8-second period, 366 (moderate) combined energy, and glassy conditions. That's a fun size.

The middle of the week after that gets blown out and messy. Wednesday morning, August 19th is a write-off. We have a massive 13ft swell from the SSW, but the guidance says the swell is predicted to be too big for this break. That's for experts only, and even then, it's gonna be a washing machine. The combined energy is a massive 3426 (strong). This is a pass.

The end of the forecast period is where it gets really interesting. Friday morning, August 21st sees the swell dropping to a cleaner 6ft from the S with an 8-second period, and glassy conditions. The wave comment says "expect very good surf conditions." The combined energy is 686 (moderate to strong).

Saturday morning, August 22nd is the absolute standout of the second week. We have a 7ft swell from the SSE with a 10-second period and a completely glassy, calm wind. The combined energy is a solid 904 (strong). The wave comment says "expect very good surf conditions." This is the one to circle on the calendar. It's a bit big for beginners, but for the advanced crew at Mangamaunu, this is going to be firing. The direction is a perfect match for the optimum SE swell direction.

Sunday morning, August 23rd is still clean, with a 4ft SE swell, but the wind swings to a light cross-onshore, so it's not quite as good as Saturday.

The bottom line: the best of the best is the Saturday morning, August 8th for the early window, and the Saturday, August 22nd for the long-range promise. The 22nd is the one to get excited about, but it's two weeks out, so keep checking back.

Rusty.
