The Lowdown
Alright, Rusty here again, this time in feet and miles.
So, we’re looking at a pretty bleak stretch for the next 16 days. The only break that showed up with any kind of hope is Chinamans Hat/Mokolii, but it’s a real dry spell for the most part. There’s a big gap of nasty surf conditions from late July all the way through the first week of August. It’s a long lull, but that’s just how it goes here sometimes.
The one ray of light is right at the tail end. On Wednesday, the 12th of August, the afternoon finally cleans up. The wind goes light and cross-offshore from the SSE at 6 mph, and the water gets glassy. The swell is a tiny 6ft from the ENE with a period of 7 seconds, giving us a combined energy of 237 – weak, but it’s something. It’s short-period, so not a lot of power, but after weeks of nothing, clean little waves at Chinamans Hat will be a welcome sight. Water temp is 79°, which is right on the money for this time of year.
This is a point break that’s inconsistent and only breaks sometimes, so don’t expect a ton of waves. The swell direction is from the ENE, but the spot works best when it’s from the NE, so it’s a little off. Still, with that clean surface and no wind, it’s your best shot. Crowds are possible, so you’ll have some company.
The rest of the forecast is just “poor surf conditions” – choppy, cross-onshore winds and lumpy junk. Not worth your time. If you’re gonna go, the 12th afternoon is the only call.
Rusty.
