The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our little corner. We’ve got a consistent run of swell on the way, but it's gonna be a mixed bag for quality. The first few days are a bit average, but there’s a definite pulse building towards the end of the run.
Kicking off on Saturday the 12th of September, Ekas-Inside is showing a 5 ft SW swell with a moderate 14-second period. Cross-off wind from the SE at 9 mph is keeping things clean, but the combined energy is at (1391). It’s surfable, but a bit 'marginal'. The water temp is sitting at 79 °F, which is pretty normal for this time of year. Crowds are sometimes a thing here, so keep an eye out.
Through Sunday the 13th and into the early part of the week, the swell bumps up a touch, hitting around 6 ft to 7 ft from the SW, with a long period up to 18 seconds. That longer period is good for the reefs here, but the cross-off wind picks up to 12-16 mph, making it a bit more work than it should be. Energy numbers are climbing through the 2600-2800 range, but the surf is still flagged as 'marginal' with these breezy conditions. This pattern holds through until the middle of the week.
Now, there’s a gap of a few days in the middle where the surf is a bit smaller and the energy dips below 1000. It’s not completely flat, but it’s not worth getting the wax out for. I'd say from late on the 18th through the 19th, the pickings are slim.
But hold on, because things start looking proper around Monday the 21st of September. Monday morning we’ve got a 6 ft SW swell, 15-second period, with a gentle 9 mph ESE cross-off. The report says 'expect very good surf conditions'. The energy is solid at (1542). This is a solid, clean session for an intermediate surfer.
The real standout, the one you want to circle on your calendar, is the end of the run. Saturday the 26th of September into Sunday the 27th. On Saturday morning we’ve got a 10 ft SSW swell, with a 17-second period – that’s proper groundswell energy at (5663). The wind is light from the SE at 9 mph. That is a lot of water moving. On Saturday afternoon it cleans up even more, with the same 10 ft and 17-second period, and the report is calling it 'excellent surf for experienced surfers' with the combined energy at (4707). By Sunday the 27th, you’ve got a 8 ft SSW swell, 16-second period, and the wind goes offshore from the ESE at 9 mph. That is the cleanest window in the whole outlook. The break is a reef, so it should handle that big, long-period swell well, but for the love of god, that’s expert territory with the size over 8 ft. Not a spot for the groms. The 10 ft swell on the 26th will be a heavy day.
So, bottom line: a lot of average, breezy days early on, but if you're an experienced surfer, the last weekend of the period – the 26th to the 27th – is where the magic is gonna happen. Get your board ready.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Ekas-Inside may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
