The Lowdown
Hey crew, Rusty here, checking the scene for Anaehoomalu Bay, A-Bay. The next 16 days are looking like a tough, drawn-out flat spell with barely a ripple.
The first week and a half, right through until August 8th, is basically dead. No swell, poor conditions, and nothing doing. That's a solid 10 to 11 days of sand between your toes and no hopes of a wave.
We finally see a pulse around Saturday, August 8th. The afternoon brings a tiny 2ft west swell with a 16-second period. That's a long-period groundswell, and it's glassy on the water, but with wave energy reading only 168 (moderate energy), it's way too small to even call surfable – very ordinary conditions.
Sunday, August 9th, is your best bet in this whole run. The afternoon glass-off with a 3ft west swell, still holding at 16 seconds, gives us 339 combined energy (moderate wave energy) and actually a "good surf conditions" call. It's tiny, but with a reef and point break setup, that long period will wrap in and offer clean little lines on a log. The water is 80°F, about 1°F warmer than average, so nothing unusual there.
Remember, anything past August 8th is a long way off, so don't book the day off work just yet. It's a barren outlook right now, but around here, the good runs tend to show up again eventually.
Rusty.
