The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks at Ekas-Outside.
We’ve got a consistent run of solid, long-period groundswell setting in. The water’s sitting at about 80°F which is pretty much normal for this time of year, nothing weird going on there. The standout feature for the whole forecast is the sheer energy in the water. We’re looking at combined energy readings regularly in the thousands, peaking well over 4000, which is strong to very strong stuff. This is a reef break, and with these long periods, it’s going to be groomed and powerful, not some messy windswell.
The first few days, from Friday the 14th right through the weekend, are consistently punchy with swell around 7 ft to 8 ft from the SSW, with periods of 15-17 seconds. The cross-off wind from the SE keeps things clean. It’s quality, but the real magic looks to be early next week. Tuesday morning the 18th, we see the wind swing to a true offshore from the ESE, pushing the 4 ft swell into perfection. It’s a gentle breeze and the wave comment says it all: excellent for experienced surfers. That is the session to circle.
By the 19th and 20th, we’re dialling up the size. Swell builds to 8 ft and then 10 ft from the SW, with period still sitting at a solid 16-18 seconds. Combined energy hits over 4000 and up to 4557, which is a lot of water moving. This is expert-only territory. If you’re experienced and hungry, the Wednesday morning session on the 19th and Thursday morning on the 20th are absolute statement swells, but you have to know what you’re doing out there.
After that peak, the swell backs off a touch but stays very rideable with 7 ft to 6 ft right through the following weekend. Into the second week, from the 24th onwards, we drop down to smaller, cleaner 4 ft to 5 ft swell, still with those nice 14-16 second periods and clean conditions. It’s still good, but the real fire is in that first week.
Overall, Ekas-Outside is going to be a proper groundswell magnet. The best on offer is that Tuesday the 18th with the offshore breeze, and then the big SW pulses on the 19th and 20th for those who can handle it. Crowds are likely here at times, but with this consistent run, there should be plenty of waves to go around.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Ekas-Outside 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.
