The Lowdown
Alright, Rusty here, looking at the run ahead for Ekas-Outside. We've got a long stretch of consistent, solid swell coming in, but a lot of it comes with a side of cross-off wind and some tide concerns. The water temp is sitting right about average for this time of year, nothing unusual to report there.
The first real action kicks off on Wednesday the 16th with a clean 6ft SW swell, period at 15 seconds, and a solid wall of energy (1327). That's a proper groundswell, long-period, so it'll have some grunt and nice lines, but the cross-off SE breeze at 12 mph means the face won't be glassy. It's rideable though, and it keeps building into Thursday the 17th with 7ft swell from the SSW, pushing the energy up to 1838. The wind stays cross-off, so you're still working for the cleanest ones.
Friday the 18th sees a slight drop to 6ft, but the wind eases to a gentle 9 mph cross-off, and the afternoon session gets a "very good surf conditions" nod. That's a solid window. Saturday the 19th is smaller at 4ft, but still clean.
Now, the real standout is Sunday the 20th. We're looking at a 7ft SW swell, period stretching out to 16 seconds, and the energy jumps to 2123 – that's a powerful, long-period groundswell. Morning winds are a gentle 9 mph cross-off from the SE, making for clean conditions. This is expert territory at 7ft, especially on a reef, but the wave quality will be excellent with that long period pushing in. Monday the 21st stays solid at 6ft, but the wind picks up a touch.
There's a slight lull Tuesday the 22nd, with swell dropping to 5ft, before another pulse arrives Wednesday the 23rd with 7ft SSW swell and energy back over 2000. That pattern holds through to the end of the month, with another big spike on Sunday the 27th of September – a massive 10ft SSW swell with a 19-second period, energy a whopping 6112. That's serious, heavy groundswell, and at 10ft it's for experts only, and with that very long period it's going to be bowling on the reef. Winds are cross-off, so it'll be clean, but you need to know what you're doing.
The final highlight is Thursday the 1st of October, a late-season pulse of 8ft SSW swell with an 18-second period and energy at 4468. Another powerful, long-period swell for the experienced crew. Crowds at Ekas-Outside are sometimes a factor, so keep that in mind.
So, the best of the bunch is the morning of Sunday the 20th – that solid 7ft, 16-second SW groundswell with gentle cross-off winds, and the morning of Sunday the 27th of September for the big-wave hunters. Plenty of surf across the whole run, but those are the standouts.
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. If you surf the same spot (Ekas-Outside) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
