The Lowdown
Alright folks, Rusty here, looking at the next couple of weeks for our little slice of coast. Honestly, looking at the charts, it's a pretty grim stretch for waves. We've got a long, dry spell on the horizon with very little surf on offer, and what's there is mostly messy and choppy. Buckle up, because it's not looking like a classic summer run.
The water at North Jetty at Eureka is sitting at 56°F, which is about 1°F cooler than usual for this time of year. Nothing too wild, just a touch on the chilly side.
We’re starting off with a blank. The first few days are a write-off, with nothing but marginal surf and poor conditions. The first half of the month is a total bust. It's not until the 19th of August that we finally see a pulse of energy, but even then it's not looking great. We get a swell building on Wednesday morning the 19th, with a 7 ft NW swell (combined energy of 726), but it's a short-period 8 seconds, and the wind is cross-onshore, making it messy. This is expert territory at that size, and the quality is just not there.
The only real standout period, if you can call it that, is a sneaky window on the 20th of August. Thursday morning the 20th sees a 3 ft WNW groundswell with a long 11-second period (combined energy of 379). The wind is light and offshore from the NW, which should clean it up nicely. This is a more manageable size, and that longer period will give it some shape. If you can get out Thursday morning, you might catch a few clean ones. But don't expect a classic day.
After that, it's back to the doldrums. The rest of the forecast is a mix of small, weak swells and choppy, cross-onshore winds. The 28th of August shows a bigger 8 ft swell (combined energy of 985), but it's short period and straight cross-onshore, making it a total mess. That's a kite-surfing wind, not a surfing one. For the rest of the 16 days, it's a whole lot of "poor surf conditions" with very little to get excited about.
Stay patient, and keep an eye on the sky. Sometimes these blanks break. But for now, it's a quiet one.
Rusty.
