The Lowdown

G’day, Rusty here. Lookin’ at the next couple of weeks, it’s a bit of a tough stretch for North Jetty at Eureka. The forecast is pretty lean, with a lot of marginal or poor conditions, but there are a few windows that might get your hopes up if you’re patient.

The first real chance to paddle out comes on Tuesday, August 13th. The morning shows some clouds with a light offshore breeze from the NW at 6 mph, and we’ve got a 7ft swell rolling in from the NW with a period of 8 seconds. The combined energy is moderate at 808, and that offshore wind should keep things clean. It’s still a bit on the big side for beginners, but for an intermediate, it’s the best of a slow start. The afternoon offers a similar 6ft NW swell with a 7-second period and lighter winds, but it’s less inviting.

Thursday, August 15th, is a real letdown. The morning brings a 2ft SW swell with a long 14-second period, but the combined energy is weak at 289, and the wind is light offshore. The long period might make it a bit straight at the jetty, so don’t expect much. The afternoon is just as flat with a 3ft NNW swell and poor conditions.

The next week doesn’t offer much relief. You’ll see a few small pulses of swell from the WNW around August 19th and 20th, with heights around 3ft, but the wind is often cross-on or light, and the combined energy stays low to moderate. The water temperature is 55°F, which is a bit colder than normal for this time of year, so don’t forget your wetsuit.

The only real standout – and I’m using that word loosely – is the morning of Tuesday, August 25th. We’ve got a 3ft SW swell with a very long 18-second period. The combined energy jumps to a moderate 530, and the wind is light and offshore from the NNW. That’s a long-period groundswell, which at a jetty setup could produce some clean, lined-up waves. It’s not big, but the quality could be there. Keep in mind, this is over a week away, so treat it as promising but not locked in.

After that, Wednesday the 26th morning has a similar 3ft SW swell with a 16-second period and moderate energy at 593, but the wind swings cross-on, making it less appealing.

Overall, don’t plan any epic sessions. The first week is a write-off, and the second week only has a couple of days that might be worth a look. If you’re desperate, the 25th is your best bet. Otherwise, it’s a waiting game. Forecasts can change, so keep an eye on it.

Rusty.
