The Lowdown
Alright folks, it’s Rusty here with the outlook for Ekas-Outside over this whole stretch. The pattern is a solid run of swell, with waves on the cards for weeks straight – there’s no gap to start, it kicks in on Friday the 4th. This is a fairly consistent spot, so when it’s in, it’s in. We’re basically looking at a clean, cross-off wind setup for the majority of this run, which is a major positive for the wave faces.
Let’s get into it. Friday morning the 4th of September sees the first pushes of a SW swell around 5 ft, with a period of 14 seconds making it a decent groundswell. The wind is cross-off from the SE at 12 mph, so it’s clean early. Combined energy is in the moderate range (828), so it’s a gentle starter.
The weekend picks up proper. Saturday the 5th, the swell builds to 7 ft from the SSW, still that 14-second period. The wind holds cross-off, and the energy jumps into the strong range (1531). This is where it starts getting fun. By Sunday the 6th we’re looking at 7 ft SSW swell with the same clean cross-off, and the energy is cranking (2136). The water temp is about average for this time of year, no major anomaly to report, so it’s comfortable.
The standout of this whole window? I’m going to call out Tuesday the 8th of September. The morning has a solid 7 ft SSW swell at 13 seconds, cross-off wind, but the energy is already strong (2803). The real gem is the afternoon session: same cross-off wind, but the swell period jumps to 18 seconds – that’s a very long period groundswell. The wave quality will be top-tier, with that extra push and longer gaps between sets making paddling out easier. The energy is very strong (3438). For a reef break like this that is fairly exposed, and with the optimum direction being SSW, this is a match made in heaven. It’s not too big for experienced surfers, but at 6 ft, it’s manageable. Just be aware, crowds are possible here sometimes.
We do dip a bit around the 9th and 10th. On Wednesday the 9th, the swell is a punchy 8 ft from the SSW, but the wind goes cross-shore, putting a bit of a chop on the face. This one is heading into expert territory for size and the wind isn't as clean. Still solid energy (2999).
From the 11th of September onwards, it’s a consistent run of clean mornings. The swell holds between 5 ft and 7 ft from the SW and SSW, all with cross-off breezes. The energy stays in the strong range, bouncing between 1396 and 2301. A specific call out for Thursday the 17th of September – it’s further out, but look at that morning: 8 ft SSW swell with a 17-second period, but with a gentle breeze (9 mph) from the SSE. That’s glassy, clean conditions. The combined energy is very strong (2994). If you can wait, that’s a dreamy morning with less wind.
Remember, that 18th of September looks similar – strong energy (3002) with a gentle breeze again on the Friday morning. The forecast is promising for that far out, but you know how it is with long-range calls – keep an eye on it.
The later afternoons in the second week will see the wind picking up to moderate, but the mornings are where the magic is. Overall, it’s a cracking run. Get on it.

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.
