The Lowdown
Alright, let’s get into it.
Look, I’m not gonna sugarcoat it: the next couple of weeks are looking pretty flat and gutless out here. We’ve got a long stretch of tiny, weak surf with hardly any push to it. The first week is a real write-off, to be honest. There’s a gap of basically no surf worth paddling out for from now until around the 16th. That’s over a week of small, messy conditions that just aren’t going to get your heart pumping.
The energy in the water is weak, readings mostly in the single digits to the 20s and 30s (11, 28, 25) – just a lot of close, small lines without any real punch. The swell direction is mostly from the west, which isn't ideal for this spot, and it’s bumpy with light cross-onshore winds for the most part.
Now, the shine starts to peek through around Sunday the 16th in the afternoon. We finally see a bit of life with a 1ft west-northwest swell, and the energy starts to climb (99). It’s still not big, but it's something. The wind goes glassy and that’s always a good look. This is the first time it really feels like you could get a clean little wave.
Then Monday the 17th is where it's at. The swell bumps up to 2ft from the west with a 14-second period, and the energy jumps to a moderate 153. The wind is dead calm in the afternoon. That is the standout of this whole forecast – a proper little glassy window with some longer-period groundswell pushing through. It won’t be huge, but it’ll be clean and have a bit more shape than anything we've seen.
After that, we drift back down again. There are a few more days with 1ft waves and light winds, but nothing that really stands out. There is a mention of a long-period southwest swell on the 21st (19 seconds, energy 82), but it's early days and that's way out there. Don’t book your flights just yet. It's promising, but we are a long way out.
For the standout, my pick is Anaehoomalu Bay_A-Bay (Big Island) on Monday the 17th. It’s a reef and point set-up, so it should handle that longer-period west swell better than a beach break. The size is small, maybe 2ft, but with that period and glassy conditions, it’s a much better wave than the size suggests. It’s a consistent spot and with it being a weekday and not huge, crowds are possible but not a total circus.
The rest of the time, just keep an eye on the horizon and don't bother getting the board too wet.
