The Lowdown
G’day, Rusty here. Look, I’m gonna level with you straight up: the next two weeks for Anaehoomalu Bay (A-Bay) are about as flat as a pond on a windless day. We’ve got a long, dry spell ahead. From now through the end of July, there’s absolutely nothing doing – the swell energy is zero across the board, and the wave comment is “poor surf conditions” every single session. That’s nearly a week of waiting for nothing.
The first real sign of life doesn’t show up until Wednesday, July 29th morning, and even then it’s just a whisper of 0.3 ft from the SW with a period of 9 seconds – weak energy (3). It’s glassy, which is the only silver lining, but honestly, that’s not enough to get wet for. That tiny bump fades into another flat spell through to the start of August.
Things get a little more interesting around Thursday, August 6th. The morning sees a 2 ft SW groundswell rolling in, period 16 seconds, with moderate energy (183). The wind is light cross-onshore, so it’s not perfect. But by the afternoon, the wind drops to glassy, and we’re looking at 2 ft of long-period swell from the west (15 seconds) and moderate energy (172). It’s still only “surfable waves but very ordinary conditions” – a 1 out of 10, so don’t expect any kind of quality. The water is a warm 80°F, which is about average for this time of year.
The best on offer across the whole 16-day window is Friday, August 7th morning. We get a 3 ft W groundswell, period 15 seconds, and the combined energy jumps to a strong 302. The wind is cross-shore from the north at 9 mph, which is okay but not ideal. A-Bay is a reef and point setup that’s fairly exposed to swell, and it likes the swell from the WNW – this is a touch off that, but it’s the biggest swell we’ll see. The water’s still around that average temp. The crowds can be around sometimes, so you might have a few mates out. This is the standout for the whole period, but it’s a long way off and the forecast confidence is lower out there.
The rest of the week after that fades again into tiny, weak SW pulses and flat conditions. If you’re a beginner, nothing here is over 5 ft, so no worries there. But for anyone else, it’s a waiting game. That 3 ft of long-period groundswell on the 7th is your best bet – it’s a point break setup, so it should handle the long period okay, but don’t expect perfection.
Rusty.
