The Lowdown

Alright, Rusty here. Let's take a look at what's on the table for the next couple of weeks.

We've got one spot on the radar to talk about: Wainui Bay Chalet. This break is exposed to the SSE, which is right where the best swell direction comes from according to the guidance. The water temperature is sitting at 56°, which is a touch cooler than average for the time of year, but nothing too crazy.

The real standout is tomorrow, Wednesday the 2nd. We've got a solid 6ft to 6ft groundswell from the SSE, with a very long period of 14 to 17 seconds. The wave energy is pumping at 1463 and ramping up to 1984 through the afternoon. The morning starts with a light offshore breeze, keeping it clean, and it holds clean through the afternoon with cross-off winds. This is the best on offer, hands down. The crowd factor is listed as "sometimes," so you might have some company, but for waves that good, it's worth it. However, a period over 15 seconds is a very long groundswell, which can make beach breaks a bit too straight; being a point break, reef, or river mouth would be its strong suit, so keep that in mind for the lineup.

Thursday the 3rd is still very good, with the swell dropping to 3ft to 4ft but from the same SSE direction. Offshore winds continue, so the surf will still be clean and fun. By Friday the 4th, the swell fades quickly, dropping to 1ft to 2ft, and we're into a long, flat run. From Friday afternoon all the way through to Monday, September 14th afternoon, there's just not much going on. A few tiny, weak waves here and there, but mostly poor conditions with lumpy wind or tiny, weak energy.

Now, here's where it gets interesting. September 15th, Tuesday, the forecast shows a massive 15ft swell from the SSW, with energy readings hitting 7130 and 7729. The next day, Wednesday the 16th, pushes up to 16ft from the S, with a massive energy of 10642 to 12030. That is a colossal amount of energy. The wind looks favorable, but the problem is the size. Anything over 8ft is expert-only, and at 16ft, this is not for the faint of heart. The forecasters are actually saying the swell is predicted to be too big for this break. Monday the 14th afternoon does have a solid 6ft with moderate offshore winds, a nice pulse before the big stuff arrives, but it's only a 3/5 rating.

So the long story short: get out there Wednesday the 2nd for the best waves of the forecast. Thursday is still a good session. Then it goes quiet for about ten days before the biggest swell of the year possibly shows up on the 15th, but it'll be a massive, expert-only affair.

Rusty, signing off.
