The Lowdown
Alright, Rusty here again. Let’s talk about Walton Rocks (Power Plant) in feet.
The whole 16-day stretch is a flat spell. No real surf to get excited about. The water is around 85°F, which is about normal for the season.
It starts on August 12th with a tiny 0.7ft easterly swell. That’s not even surfable. Thursday the 13th morning is even smaller at 0.3ft, even with offshore wind. Through the weekend, the biggest bump is about 2ft on Saturday morning, but with a 4-second period, it’s just bumpy windswell. The energy is only 25, which is weak.
All of the first week is the same story: tiny waves and poor conditions. Into the second week, we see a little more period – 10 seconds on the 19th – but the height is still only 1.0ft. Energy is 17. A few mornings are clean or glassy, like the 20th, but with that tiny swell, you won’t catch anything.
The biggest we see all month is 2ft on the 23rd and 25th, but with a 4-second period, it’s just choppy and weak. The wave comment for every single day is “poor surf conditions.” There are no standout sessions. The energy never gets above moderate, and the highest is 45.
If you’re a beginner looking for whitewater, maybe, but for anyone else, this is a total blank. The area goes flat like this sometimes. It’ll come back, but not in this 16-day window.
Rusty.
