Right, g’day, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
First thing you need to know: the water’s sitting at a warm 80°F at the moment, which is about 2°F above what we’d normally expect for this time of year. Nothing wild, but it’s a touch toastier than average.
Alright, the big picture: we’ve got a long, drawn-out run of flat or almost flat days ahead. The first half of the 16-day window is basically a write-off. You’ll be waiting until Wednesday, July 15th, before anything even worth paddling out for shows up. That’s a solid gap of nearly five days with no real surf to speak of. But once Wednesday rolls around, we get a little pulse of life.
The standout window is Wednesday, July 15th, into Thursday, July 16th. Wednesday morning is the pick of the whole forecast. At Anaehoomalu Bay (A-Bay), we’ve got a 3ft swell rolling in from the west, with a 16-second period. That’s proper groundswell, long and clean, the kind that wraps around the reef and point nicely. The wind is glassy, and the water’s clean. The combined energy hits 310 (moderate) – enough to get a few decent ones. The swell direction is a good match for the break’s optimum from the WNW, so it’ll line up well. It’s a consistent spot, but you can expect company – crowds are sometimes an issue here. Still, for those couple of days, it’s the only real game in town.
The rest of the fortnight? Flat. After Thursday afternoon, the swell drops away fast. By Friday, July 17th, it’s back to 2ft and 2ft with poor conditions, and from Sunday, July 19th onward, it’s mostly zeros on the board. The last week is a total flat spell, with only a trace of swell barely registering a combined energy of 9 or 23 here and there. Not worth your time.
So, honestly, if you’ve got a flexible schedule, aim for Wednesday morning, July 15th, or Thursday afternoon, July 16th, at A-Bay. That’s your best shot. The rest? It’s a waiting game.
Rusty out.
