The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s heading our way for Ekas-Outside.
We’ve got a solid run of surf on the cards, starting from Wednesday the 5th of August. The water temp is sitting at 79°, which is bang on average for this time of year, so no surprises there. The whole pattern is driven by a persistent SSW swell, and with the wind hanging in the SE, we’re looking at clean, cross-off conditions for the vast majority of the period. That’s a real positive – the waves will be well-shaped, even if the wind isn’t glassy.
The first few days, from Wednesday the 5th through to Sunday the 9th, offer swell heights around 5ft to 8ft. The period is a juicy 15 to 17 seconds, so that’s proper groundswell energy. The combined energy is sitting in the moderate to strong range. It’s clean, but the scores are a bit subdued early on – likely a tide issue or just not quite the magic window. Still, it’s a good intro.
Now, the real standout window opens up on Monday the 10th of August. Monday afternoon sees the swell bump up to a solid 10ft from the SSW, with a very long period of 19 seconds. The combined energy jumps to a powerful level, and the wind is a manageable 12 mph cross-off. This is the kind of long-period groundswell that Ekas-Outside was built for – a reef setup that loves that direction. It’s going to be a proper session, but at 10ft, it’s getting into big-wave territory. Not one for the beginners.
The second standout is further out, on Tuesday the 18th of August. The afternoon looks like the pick of the second week, with 12ft of SSW swell, a 18-second period, and a massive combined energy. That’s a huge amount of energy. The wind is still cross-off, so it’s going to be powerful and clean. Again, this is for experienced surfers only.
The run continues through to the end of the forecast, with the 20th of August offering another 10ft day with light winds. The consistency is there, and the reef will handle the long period well. Crowds are listed as “sometimes,” so you might get a few locals out, but it’s not going to be a zoo.
The best on offer? Monday the 10th of August afternoon and Tuesday the 18th of August afternoon. The 10th is closer, so more reliable. The 18th is a long-range call, but it looks massive. If you’re an experienced surfer, mark those dates.
Rusty, signing off.
