The Lowdown
Alright folks, Rusty here. Let me break down what’s happening for Anaehoomalu Bay, also known as A-Bay. It’s a reef and point setup over on the Big Island, and this stretch of the forecast is a real bummer for us surfers.
Right off the bat, we’ve got a long, empty stretch. From today, Wednesday the 22nd, all the way through to Wednesday the 29th of July, there’s absolutely nothing showing up. The ocean is flat, with no swell energy to speak of. The wind is mostly light and cross or glassy, which would be perfect if there was any wave to ride, but there isn’t. It’s a tough run of poor surf conditions.
The first tiny glimmer, and I mean tiny, shows up on Thursday the 30th of July. We’re looking at a little 1ft swell from the southwest, with a long period of 18 seconds. That’s a groundswell, but the energy is weak, only 49 (for context, that’s next to nothing). The wind is onshore and light, but the water temp is about average for the time of year at 80° around the start of the period. The problem is, the swell direction is from the WSW, and A-Bay really needs a WNW swell to work properly. So this won’t shape up well.
Through the end of the first week of August, things stay flat. We get more of those tiny 1ft to 1ft pulses from the west and WNW, but the combined energy never cracks 100. The strongest it gets is on the morning of Thursday the 6th of August, with a reading of 91. That’s still weak energy. The swell periods are hanging around 12 to 14 seconds, which is decent enough for shape, but the size is just too small to get excited about. The wind is often light and glassy, especially on the afternoon of the 6th with a dead calm, but the waves aren’t there to enjoy it.
Honestly, there are no standouts in this 16-day window. The only break in the area, A-Bay, just doesn’t get any proper swell. The whole forecast is a flat spell. Don’t put the board on the roof just yet.
Rusty.
