The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, we’ve got a solid run of SSW swell lining up for Ekas-Outside, a reef set-up that’s fairly consistent and pretty exposed to the action. The water temp is sitting about average for this time of year, so nothing weird there. The trade-off is that the wind is gonna be a persistent cross-off from the SSE for most of the run, which keeps things clean but not perfectly glassy. The swell is hanging around the 5 ft to 8 ft range for most of the first week, with periods that swing from 14 seconds up to a very long 19 seconds on Tuesday the 8th. That long period groundswell is a real treat for a reef, giving you proper lines and energy, though the combined energy is strong (2754) and builds into the week. The catch is the tides and conditions have it marked as marginal, so you’ll want to pick your banks.
The real standout window starts to shape up from Saturday the 12th. Saturday afternoon sees the swell dip to 5 ft from the SW, with a 14-second period, and the wind drops to a gentle breeze from the SE. That’s the best call for a cleaner session, and the energy is still solid (1566). Then Saturday the 19th and Sunday the 20th look like the big guns. Saturday the 19th has 8 ft of SW swell, 16 seconds, and a very strong energy reading (3427). That’s getting into expert territory—over 8 ft is for the crew who know what they’re doing, especially on a reef. Sunday the 20th morning is the biggest of the run: 10 ft from the SW, a very long 21-second period, and a massive 6923 combined energy. That’s a serious groundswell. It’s going to be a raw, powerful beast, best left for the experienced surfers, and the wind will be a moderate breeze from the SE, so still cross-off, not perfect. There’s a chance of crowds here, as it’s a spot that can get busy.
In the second week, the swell holds but the wind picks up a bit, especially on the 15th and 16th with 19 mph breezes. The best quality in that later stretch looks like Friday the 18th afternoon: 7 ft from the SSW, 16 seconds, and a gentle breeze. That’s a strong, clean option, though the energy is strong (2431). Overall, the standout is Saturday the 12th for the cleaner conditions, and Sunday the 20th for the raw power if you’re up for it. Keep in mind, the long-range stuff like the 20th is promising but less certain.
Stay safe out there.
