The Lowdown
G'day, Rusty here. Let's talk about what's cookin' at Raglan-Manu Bay.
We start with a total bummer. Friday the 28th of August is a washout thanks to a funky cross-onshore breeze and weak, short-period slop. Saturday the 29th of August is a two-faced day: the morning's a bit grim with light rain and a crosswind, but the afternoon turns glassy with a WSW breeze and the swell dropping to 2ft. It's clean but tiny. After that, it gets ugly. Sunday the 30th of August is pounded by a fresh to strong cross-onshore wind, with the swell hitting 7ft and the energy all over the shop (559). That 17-second period on a point break like this means fat, hard-to-connect sets.
Monday the 31st of August brings serious muscle – 13ft of swell and a combined energy reading of 4633 in the morning, blowing out to 6123 in the afternoon. That's heavy, but the wind is screaming from the SW at 22 mph, putting a nasty cross-chop on it. That's for experts only, and even then, it'll be a grinder. Tuesday the 1st of September stays big and messy with 12ft to 10ft and the wind still strong. The whole first week is looking lumpy and blown-out.
The one that catches my eye, way out there, is Saturday the 12th of September. It's a long-range call, so don't bank on it, but the morning shows a clean cross-offshore breeze from the SSW at 13 mph and a 6ft swell. The energy is moderate (517) and the period is a short 7 seconds, so it'll be a bit soft and peaky, but clean conditions change the game. The afternoon holds 7ft from the west with a light cross-shore breeze. It's not pumping, but it's the cleanest slot in the entire two-week forecast.
Overall, there's a ton of swell from the 31st through to the 11th of September, but a relentless cross or cross-onshore wind wrecks it. The water is sitting at 57°, which is about average for this time of year. This spot can get a crowd when it's on – it's world-class and 'sometimes' gets busy – but for most of this run, you won't have to worry about company. The first real option isn't until Saturday the 29th of August, but the only true standout is that far-out Saturday the 12th.
Rusty.
