The Lowdown
Alright, folks, Rusty here. Let’s break down what we’ve got coming up. It’s a mixed bag for the next couple of weeks, with some quiet spells and a couple of moments where things might just line up. You’ll need to be patient and pick your moments.
The first few days are a bit of a washout. There’s some swell, but it’s short-period and the wind is messing with it. We’re looking at poor conditions through the start of the week. Wave energy is moderate, in the 200s. You’ll see waves, but they’ll be lumpy and uninviting. Not worth your time.
Come Wednesday the 19th, the swell builds a bit, hitting 6ft with a solid moderate push of energy at 610. But the period is still short at 7 seconds, so it’ll be crumbly. The morning light breeze and offshore wind might make it semi-rideable at North Jetty at Eureka, but it’s still marginal at best. Thursday and Friday drop off again, swell gets smaller, winds go cross-onshore. That’s a write-off.
Now, the weekend. Saturday the 22nd afternoon sees the swell start to build again, up to 7ft with energy at 577. But period is still short at 8 seconds and it’s cross-onshore, so it’ll be a bit of a battle. Sunday the 23rd is more interesting. A 8ft NNW swell rolls in with strong energy at 975 and a slightly better 9 second period. The wind is light, but still cross-onshore. It has power, but not great quality. Still marginal.
The standout for me is the morning of Monday the 24th. The swell is still a solid 6ft, but the wind drops to almost nothing, just a slight air from the west. It’s still cross-onshore, but with that light wind, it should be much cleaner. The energy is still chunky at 635. It’s not perfect, but of everything on offer, that’s your best chance for a decent session. The period is still just 8 seconds, so no long-period grunt, but it could be fun.
After that, the taps get turned off. Wave heights drop right down to under 3ft, and we get a few days of small, weak surf with long-period background swell that has no power. That’s from the 25th through the 31st. Mostly poor, with the odd pulse of energy but no real rideable waves. That’s the gap you need to know about.
Then, look at Thursday the 27th and Friday the 28th. The swell starts to pick back up, with 6ft and 6ft respectively. Energy is moderate to strong, around 547 and 511. The winds are light and offshore in the mornings, which is a big positive. Period is still short at 7-8 seconds, so again, not classic groundswell, but with clean conditions it might be worth a paddle. That Friday morning is looking like the pick of that run, with a 6ft NW swell, 8 second period, and that light offshore breeze. Could be clean and fun.
Then we hit September and it’s more of the same. Small, weak, and not much to get excited about. Wave heights barely break 3ft.
So, no massive swell in this window. The standout is that early Monday morning on the 24th, where clean conditions meet a solid, if short-period, swell. The other little peak is the Friday morning on the 28th. Everything else is either poor, small, or suffering from bad winds. Patience is key. And remember, the long-range stuff is promising but not set in stone.
Rusty out.
