The Lowdown
Alright folks, Rusty here. Let's break down the next couple of weeks at North Jetty at Eureka.
First off, it's a quiet start. You're looking at a few days of soup before anything really gets going.
The first real chance for a wave is on Thursday, September 3rd. The morning brings a northwest swell of about 7 ft, with a cross-off wind from the SSW keeping things clean. The combined energy is a solid 921 (moderate). The afternoon gets bigger, hitting 10 ft from the northwest, but the cross-shore wind will put a bit of a chop on it. That energy jumps to 2754 (strong). That's expert territory at that size.
Now, the standout is Tuesday, September 8th. The morning has an 8 ft swell from the NNW with a clean offshore wind from the NW. Energy is 861 (moderate). The afternoon jumps to 10 ft, but the wind turns cross-on. Still a powerful, big-wave day.
The absolute gem of the whole outlook is Wednesday, September 9th, in the afternoon. It’s a total glass-off. The wind is glassy from the WNW at just 3 mph. The swell is a small 2 ft from the southwest, but with a period of 19 seconds (very long period groundswell). That long period means it’s got real shape and energy. It’s a special, clean window for the jetty. The energy is 609 (moderate), but the quality is top-notch.
The following week has some promise. Monday, September 14th looks good in the morning with a 5 ft northwest swell and offshore wind, giving a combined energy of 1210 (strong). The period is 14 seconds, so it’s a proper groundswell. Crowds are "sometimes" here, so you might not be alone. Wednesday, September 16th is a big finish. The morning has a 5 ft northwest swell, but the afternoon is a monster: 12 ft from the northwest. The energy is 1947 (very strong). The wind is cross-on, so it’s for the experts only.
Water temp is sitting at 57°F, which is about normal for this time of year.
Bottom line: the session to clear your calendar for is that glassy, long-period swell on Wednesday the 9th. The rest is a mix of good, clean days and big, challenging ones.
Rusty.
