The Lowdown
What’s up crew, Rusty here. Let's get into it for the North Shore. We are looking at a pretty flat picture for the foreseeable.
To start the forecast period, there’s nothing on the menu. The first window is Tuesday the 11th, and it's a 1-foot swell from the west with a period of 10 seconds. The water's a warm 80°F, which is about normal. Wind is a cross-off from the east at 12 mph. The combined energy is super weak at 30. It's clean, but there's nothing to catch.
Wednesday and Thursday the 12th and 13th are equally poor. By Friday the 14th, the swell is gone in the morning. Saturday the 15th brings a 1-foot west swell, but the wind is cranking at 22 mph from the northeast, making it all a bit messy.
Now, there is one bright spot that might get your hopes up. On Sunday the 16th, we see the wind clock to an offshore out of the east-southeast. The swell is still only 1 foot from the west-northwest at 12 seconds. The energy is pretty weak (41), but the offshore wind will make it glassy. For a skilled longboarder, there could be a couple of fun ones at Pinballs early. It's a reef, so it’s for experts, but the wind will be clean.
Monday the 17th is similar: offshore wind from the east at 12 mph and a 1-foot west-northwest swell. The energy is still low (36). It’s a mellow, clean setup, but tiny.
After that, from the 18th all the way through to the 26th of August, it's basically a flat spell. Swell heights stay at 1 foot or less, with the wind mostly cross-off. The biggest combined energy we see is 69 on Wednesday the 19th, but that's still nothing to write home about.
So, here’s the truth. This is a classic North Shore summer lull. For the next 16 days, the only real chance you have for half-decent conditions with good wind is the early mornings of August 16 and 17. If you want actual rideable surf, you need to look elsewhere. It's a long stretch of flat days.
Rusty.
