The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s heading our way for the next couple of weeks.
Alright, to be straight with you, the next 16 days are looking pretty slim for any decent waves. We’ve got a little window of surfable but not amazing conditions right at the start, and then a long, flat spell that stretches from the 17th of July right through to the 30th. There’s just nothing on offer for the majority of that time. The only real chance of getting wet is on the 15th and 16th.
The best of the very little we have is Anaehoomalu Bay, A-Bay. It’s a reef and point setup, consistent, and fairly exposed to the swell. For the Wednesday the 15th and Thursday the 16th, we’re looking at a small, long-period groundswell pushing in from the west at 3ft. The period is a solid 15 to 16 seconds, which is a very long-period groundswell. That’s going to wrap around the point really nicely, giving you some proper shape and energy, but those long gaps between sets will make the paddle out a bit easier. The combined wave energy is moderate, sitting at 302 to 310 during the best windows.
The real standout here is the Wednesday afternoon. The wind drops to a glassy 3 mph from the southwest. That is as clean as it gets. The water is a warm 80°, which is about average for the time of year. The swell is a touch small, but with that kind of glassy condition, it’s your best bet. Thursday afternoon also shows glassy conditions with a light offshore from the northwest, so that’s another good window, but the swell energy is a little lower.
After that, it’s a write-off. From the 17th of July through the 30th, the swell drops to almost nothing, and the wind is either cross-on or light offshore on tiny, unrideable bumps. There’s a long stretch of zero energy in the water from the 21st to the 24th, and again from the 27th to the 30th. It’s a bleak outlook for the rest of the period.
So, for the next two weeks, you’ve got a couple of small windows on Wednesday the 15th and Thursday the 16th at A-Bay. Make the most of them, because after that, it’s a long, flat spell.
Rusty.
