The Lowdown
Alright, Rusty again. Let’s break it down in feet and miles per hour.
The next two weeks are pretty average for North Jetty at Eureka. The first week is mostly small and messy. Water temp is about 57°F, which is normal for this time of year.
Friday morning, September 4th, we’ve got a 7ft northwest swell at 10 seconds. The energy is moderate (959), and the wind is light cross from the SW at 6 mph. It’s rideable but not clean. The afternoon drops to 6ft, still cross-on, so a bit bumpy.
Saturday and Sunday are a wash—small, poor conditions, weak energy. Monday and Tuesday stay small and choppy. Then Wednesday afternoon, September 9th, the wind goes glassy, and a tiny 2ft, very long-period swell from the SW at 19 seconds shows up. Energy is 264—moderate. You’ll need a longboard, but it’ll be glassy.
Thursday, September 10th, afternoon is a standout. Glassy conditions, 3ft from the SW at 17 seconds, energy at 676. Clean, small, perfect for a cruiser.
The real winner is Saturday morning, September 12th. Glassy, 3ft from the SW at 14 seconds, energy 514. That’s a clean, lined-up morning session. The afternoon gets a 16 mph cross-off from the SSW, which cleans it up but gets a bit breezy.
The second week sees building swell. Sunday and Monday (13th and 14th) hit up to 7ft, but the wind is poor—cross-on and choppy. Tuesday morning, September 15th, has a 5ft NNW swell with offshore wind, energy 1076—strong. That’s a powerful wave, but a bit chunky at 10 seconds.
Friday, September 18th, afternoon offers a 7ft NW swell at 8 seconds, energy 1016, with light cross-shore wind. A lot of power, but the short period makes it crumbly.
Best of the lot: Thursday afternoon, September 10th, and Saturday morning, September 12th, for clean, glassy conditions. If you want size, Monday the 14th and Friday the 18th have the most power, but the wind will be a factor.
