The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking.
We’ve got a solid run of groundswell lining up for Ekas-Inside, starting Friday afternoon, July 31st. The swell is coming from the SSW, which is exactly what this reef likes. The water is sitting at 80°, which is bang on average for the time of year, so no surprises there.
Friday afternoon kicks things off with a 4ft SSW swell, with a very long period of 17 seconds. That’s proper groundswell energy, and the combined energy is a strong 1535. The wind is a cross-off from the SE at 16 mph, keeping things clean. It’s a solid start, but the surf is a bit marginal for the tide, so it’s more of a warm-up.
Saturday morning, August 1st, is where it starts to get good. The swell bumps up to 5ft, still 16 seconds period, and the wind drops to a gentle 9 mph cross-off. The energy is still strong at 1370. This is a nice window for a beginner-friendly reef with clean, lined-up waves. But the real standout comes Sunday morning, August 2nd. We’re looking at a 7ft SSW swell, 16-second period, and the combined energy is a beefy 2306. Wind is a gentle cross-off, and the conditions are marked as excellent for experienced surfers. This is the pick of the first week – solid, powerful, and clean. If you’ve got the skills, be on it.
The pattern holds through the next week, with the swell staying between 6ft and 7ft, mostly in the 14-17 second range. The wind remains a consistent SE cross-off, though it does pick up to 19 mph on a few afternoons, which will put a bit of texture on the surface. The mornings will be the cleaner sessions.
Now, looking further out, there’s a big spike on Tuesday, August 11th. The swell jumps to 12ft from the SSW, with a very long period of 19 seconds. The combined energy is a massive 9368 – that’s a serious amount of water moving. This is expert territory only. The waves will be heavy and powerful, and with that long period, it’s going to be pitching hard on the reef. Wednesday the 12th sees 10ft, and then Saturday the 15th another 10ft to 12ft pulse. These are the biggest, most powerful swells of the outlook, but they’re for the experienced crew only. The wind stays cross-off, so it’ll be clean, but it’s going to be a handful.
For the average surfer, the best bet is still Sunday morning, August 2nd. That’s your clean, strong, manageable window. For the experts, the big pulses on the 11th and 15th are the ones to watch, though they’re a long way out, so keep an eye on the forecasts.
