The Lowdown
Alright mate, let’s break down the next couple of weeks for Anaehoomalu Bay (A-Bay). I’m looking at the whole 16-day window and, honestly, it’s a tough one. We’ve got a real flat spell coming up, so don’t expect much action on the reef and point here. The water temp is sitting at 80°F, which is pretty normal for this time of year, so that’s one thing that’s not letting us down.
We start off with a bit of a tease on Friday, July 17th. The morning shows a small 2ft swell out of the west, with a period of 14 seconds – that’s a nice long groundswell, but it’s coming in with a cross-onshore breeze from the northwest at 3 mph. The energy is moderate at 203, but the conditions are “poor,” so the waves will be messy. That wind is a real buzzkill, and the wave comment says it all. The afternoon drops to 2ft, same story.
Saturday the 18th is a bit of a mixed bag. The morning is still small and cross-onshore, but the afternoon glassed off! Wind swings to NNE at 3 mph, going glassy with a 2ft west swell. The swell period is 13 seconds, still a decent groundswell, but the energy is low at 87. The wave comment says “surfable waves but very ordinary conditions.” It’s the best we’ll see for a few days, but it’s tiny.
From Sunday the 19th onward, the swell just drops off a cliff. We’re looking at 1ft, then 1.0ft, then 0.7ft on Monday, and by Tuesday the 21st, it’s flat – literally zero swell energy. The wind is light and glassy or cross at times, which is a shame because there’s nothing to ride.
This dead flat spell runs right through the rest of July and into the beginning of August. There’s a solid 10-day gap from the 21st of July until the 1st of August where there’s practically no surf to speak of. The energy values are all in the single digits or zero.
On the very last day of the forecast, Saturday, August 1st, we see a tiny blip. The afternoon shows a 1ft west swell, period 12 seconds, with glassy conditions from the NNW at 3 mph. The energy is still low at 47, and the wave comment says “poor surf conditions.” It’s too small to get excited about.
So, to be straight with you, there’s no standout day here. The only window that even comes close is Saturday afternoon, July 18th, with the glassy conditions, but the swell is barely there. It’s a long, flat run for A-Bay. For a break that’s usually fairly consistent, this is a poor run, but it happens. The crowds will be non-existent, but that’s because there’s nothing to crowd for.
