The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for this stretch of the North Shore.
Honestly, it's a tough run ahead. We've got Chinamans Hat/Mokolii on the radar, and it’s going to be a long wait for anything decent. The entire first week and a half is a write-off. From Thursday the 6th right through to Tuesday the 18th of August, it's just poor surf conditions every session. The wind is stuck in a cross-onshore pattern, not giving us a clean face to work with. The swell is coming from the ENE, which isn't its optimum NE direction, and the periods are short, mostly 5 to 8 seconds. There is moderate wave energy (242) on Thursday morning, but the wind just kills it. This is not a spot you want to be at unless you're just floating around.
We don't get a sniff of anything until the tail end of the run. The best of a bad bunch looks like Tuesday morning, the 18th of August. The report shows a "marginal" call with a 1 out of 10 score. The swell is a solid 8 ft from the ENE, with a moderate combined energy (672). The wind is a lighter cross-on from the east at 9 mph. It's still not ideal, but it's the cleanest window in the whole forecast. The period is still a short 8 seconds, so expect it to be a bit lumpy and choppy, but at least the wind won't be howling. This is a point break, and with it being inconsistent, you'll be waiting for sets, but there might be a few workable ones in there. The water temp is sitting at a normal 80° for this time of year.
After that, it drops back into the poor zone again through the 21st. So, if you're really jonesing, set your alarm for that Tuesday morning, but keep the expectations low. It’s a long blank run until then.
