The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks. It's a lean stretch, so don't get your hopes up too high.

The only break worth talking about is Anaehoomalu Bay, also known as A-Bay. It's a reef and point setup, so it's got some structure to it. The water temp is sitting at 80°, which is pretty much normal for this time of year, so nothing crazy there.

We're starting off on Thursday the 16th. There's a little pulse of energy coming in, with a 3ft swell from the west. The period is a long 15 seconds, which is a proper groundswell, but it's a bit on the weak side with combined energy of only 275. The wind is light and offshore, which is a good sign, but the forecast is calling it "marginal" and a score of 1 out of 10. It's small, but it's the best we've got for this first day. Friday the 17th is a mixed bag. The morning is a write-off with cross-on winds, but the afternoon turns glassy. The swell drops to 2ft, and the energy falls off to 146. It's surfable, but don't expect anything to write home about. Saturday the 18th is more of the same – tiny 2ft waves and glassy in the afternoon.

From Sunday the 19th all the way through to Wednesday the 29th, it's a flat spell. There's barely a ripple. The combined energy numbers drop to zero or single digits, and the swell height is a flat line. It's a long, quiet run. If you're looking for a paddle, you're better off finding a pool.

Finally, on Thursday the 30th, there's a glimmer of hope. The afternoon shows a 2ft swell from the north, with a short period of 8 seconds. The energy picks up to 78, and the wind goes glassy. It's still "ordinary," but after that long dry spell, it's something. Friday the 31st fades back to tiny, poor surf.

So, for the best on offer, you're looking at Thursday the 16th morning. It's not going to be a world-beater, but it's the only day with a clean, offshore wind and a long-period swell. The water is warm, the crowds are only "sometimes", so you might get a few waves to yourself. Just keep your expectations low. It's a small, clean wave for the intermediate crew. After that, it's a long wait until the 30th, but that one is a bit of a gamble with the short period. All in all, it's a tough outlook.

Rusty.
