The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the North Shore over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s flat. Proper flat. We’re staring down a long, dry spell. From Wednesday the 26th of August all the way through to the morning of Wednesday the 9th of September, there’s nothing doing. The swell energy is barely registering, with numbers like 32 (weak energy) and 22 (weak energy), and for days at a time it’s a big fat zero. The wind is a constant moderate cross-off from the ENE, which would be nice if there was anything to surf, but there isn’t. The water temp is about average for this time of year, nothing to write home about.
So, we’ve got a solid gap of nearly two weeks with no surf on offer. It’s a tough run for the North Shore, but this kind of blank spell can happen.
Now, things finally start to stir on Wednesday the 9th of September. Waimea Bay/Pinballs (Oahu) shows a pulse of life. The swell is still small, around 2 ft to 3 ft out of the NW, but the period jumps to 14 seconds. That’s a proper groundswell, carrying some real energy. The combined energy jumps to 154 (moderate wave energy) and then 215 (moderate wave energy). The wind on Wednesday afternoon goes clean and cross-off from the S, which is a major positive. The catch? The swell is still tiny for a spot like Waimea, and with that long period, it’s going to be very walled-up and unmakeable on a beach break, but it might offer a few peelers on the reef. It’s a faint glimmer.
The best of the whole window looks to be Thursday the 10th of September morning. The swell is up to 3 ft from the NW, with a period of 12 seconds and combined energy of 244 (moderate wave energy). The wind is a clean cross-off from the S, which is exactly what you want. This is about as good as it gets in this forecast, but even then, it’s only marginal at best. The water temp is still about average for the time of year.
Honestly, if you’re desperate for a paddle, Thursday the 10th is your only real shot, and even then it’s a gamble. The rest of the time, leave the board in the car.
Rusty.
