The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
Well, I gotta be straight with you – it’s a pretty grim stretch ahead for Chinamans Hat/Mokolii. The whole 16-day run is a write-off for decent waves. The wind is locked in from the east and east-northeast, blowing cross-on shore, and that just kills any chance of clean faces. The swell is mostly short-period, choppy stuff that’s not doing us any favours.
From Sunday, July 19th right through to the end of the month, it’s a constant battle against onshore wind. We’re looking at chest to head-high waves (5ft to 8ft), but the wind is just ruining it. The combined energy is moderate at best, getting up there towards the end of the week (466 to 590 on the 24th and 25th), but with the wind howling it’s just lumpy, bumpy, and not worth paddling out for. At times, especially with the stronger winds and bigger, choppier waves, this setup honestly looks more interesting for the kite surfers than the paddle crew.
There’s a tiny flicker of hope around July 27th when we see a long-period groundswell from the east (15-17 seconds) and the combined energy jumps up to 942-1204, which is strong. But the swell is small (3ft to 5ft) and that damn cross-on wind is still there, making it chunky. The 27th morning is only rated as marginal at best. It’s just not enough to get excited about.
The first week of August is more of the same: small, messy, onshore. The swell direction is from the east, which is not the optimum for this spot (it wants NE), so even if the wind backed off, it wouldn’t be firing.
So, no standouts here. No clean windows. It’s a solid 16-day blank. Sorry, gang. Forecasts can change, but right now, it’s a time to work on the quiver or find another hobby.
Rusty.
