The Lowdown
Alright, let's have a proper look at what's shaping up for North Jetty at Eureka.
To be straight with you, the next week and a half or so is pretty grim. The first ten days or so, from Saturday the 15th right through to at least Monday the 24th, are a write-off. The swell's small and weak or, when it does pick up, the wind's just junk. There are a lot of dead days in there.
The first real flicker of something comes around Wednesday the 19th, but even then it's marginal. The swell's pushing near 6 ft (6 ft on the morning) from the NNW with a short period of 7 seconds. The combined energy reading is strong though, over 600, so there's some push in the water, but the wind is a light onshore breeze early, then cross-onshore in the arvo. The water's sitting at 56°F which is a touch below average for this time of year, not weird cold, but you'll feel it.
Honestly, the best the whole outlook can manage is a bit of a nod towards Saturday the 29th. Saturday morning the swell is 8 ft from the NNW with an 8 second period, and the wind is light and from the NNW, straight offshore. The energy’s cranking hard at 931. That is expert territory for sure – over 8 ft is big and that period isn't the longest, so it'll be a bit fat and lumpy. The afternoon looks even bigger, hitting 10 ft with the same period, still with light winds (energy hits 1044), but again, only for the very experienced. The cross-onshore tickles it clean enough for what it is.
For the average surfer there is simply nothing on the cards here. Not a single standout session for a weekend warrior. The setup, with all that onshore wind and building swell over the beach/jetty, might actually look more appealing for a kite surfer than a paddler for most of this run.
Keep an eye on that last Saturday though. It's a long way off, but it's the only thing on the horizon.
