The Lowdown
Right, let's get this out of the way: the next week and a half is going to be more about managing expectations than mythical barrels. Ekas-Outside will be rideable, and it's clean, but the tide's been messing with the shape. We get a solid start on the 9th with 2.4m of SSW groundswell, but that 16-second period is making it a bit too straight, and the 25 km/h cross-off keeps things honest. Water temp is about average for the season at 79°F.
Through the 16th, it's a similar story: 1.4m to 2.1m of swell, mostly SSW for the start and then swinging SW, with the winds bouncing between 15-25 km/h. There's energy in the water, hitting 2864 on the 9th and staying in the four-digit range, but it's not lighting up the bay. It's there for the taking, just don't expect a highlight reel.
Now, here's the good news. The 20th of September is looking like the main event. That Sunday morning has a 2.3m SSW swell with a 16-second period and a much nicer 15 km/h offshore breeze from the SSE. The energy's up around 2780 and the report flags it as excellent for those who know what they're doing. That's a paddling morning for me. The next day, the 21st, is nearly as good – 2.4m of SSW swell and a light 15 km/h SE wind – also rated top shelf for experienced surfers.
Looking further out, the 24th of September is a big one on the charts. We're talking 2.5m SSW swell and a 16-17 second period with combined energy over 3500. That's proper strong swell, and while it could be a barrel show, it's also getting into the "experts only" territory. It's a long way out, so don't book your flights yet, but it's got potential.
So if you're on the fence, wait it out. The early part is a grind, but that window from the 20th to the 24th is where the real swell comes alive. Patience is a virtue, and that Sunday the 20th is the reward.

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.
