The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of groundswell lining up for Ekas-Outside, a reef break that’s fairly exposed to the south-west and works best with a SSW direction. The water is sitting at 80°, which is about average for the time of year, nothing unusual.
The first surf worth talking about kicks off on Wednesday, August 19th in the afternoon. We’re looking at a clean 8ft swell from the SW, with a very long period of 18 seconds. The combined energy is strong at 4135, so you can feel the power. The wind is a moderate breeze from the SE at 12 mph, which is cross-offshore, keeping the face clean. That long period means the sets will have serious push, and the lines will be well-defined. The swell is over 8ft, so this is for experienced surfers only.
The pattern continues through the rest of the week. Thursday, August 20th keeps the 8ft SW swell, period dropping to 16 seconds, still with that clean cross-off wind. The energy is still very strong at 4117 in the morning. Friday the 21st sees a slight drop to 7ft in the morning, then a bump back up to 8ft from the SSW in the afternoon. The wind stays cross-off from the SE, though it picks up to 16 mph in the afternoons. The weekend is consistent, with solid 7ft to 7ft SSW swell, periods around 15-16 seconds, and still clean despite the moderate breeze.
Now, the real standout for me is the Friday, August 28th morning session. The forecast shows a 8ft swell from the SW with a period of 16 seconds, and the combined energy is pumping at 3143. The wind is a gentle breeze from the SSE at 9 mph, which is cross-offshore, and it looks like excellent surf conditions for experienced surfers. That’s your best window. It’s a big swell, so bring your balls and your biggest board.
After that, the swell slowly fades through the end of August and into the first days of September. You’ll see a new pulse of SW groundswell starting on Monday, August 31st afternoon, with a 7ft swell and a very long 19-second period, 3485 energy. That holds into Tuesday, September 1st, with 8ft SW swell and 18-second periods, showing strong energy again. The wind stays cross-off and clean. It’s a promising run, but being that far out, keep your fingers crossed.
Overall, the reef is handling the long-period energy well, and the consistent cross-off wind is the real hero here. The first week is solid, but the 28th of August is the one to circle on the calendar. That’s a proper session.
Rusty.

Information about the Ekas-Outside Surf forecast
The above surf forecast table for Ekas-Outside provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ekas-Outside can be found by selecting the local surf guide option on the grey menu. Our Ekas-Outside surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
