The Lowdown
Alright, Rusty here again, giving it to you in feet and knots.
We’re looking at Ekas-Outside, a reef break that’s fairly exposed to the swell. The water temp is 79°, pretty average for this time of year.
Monday afternoon, September 7th, kicks off with a 7ft SSW swell, 14-second period. The energy is solid at 1891 (moderate to strong). Wind is 11 knots cross-off from the SSE, so it’s clean, but the forecast says it’s marginal due to tide. Tuesday the 8th, the swell builds to 7ft from the SSW, 13-second period, energy jumping to 2933. That afternoon, the period stretches to 18 seconds – a proper long-period groundswell – and energy hits 3716. Wind stays cross-off, clean but marginal.
Wednesday the 9th is the biggest of the early run: 8ft from the SSW, 16-second period, energy at 3569. That’s getting into expert-only territory. Wind is still cross-off, keeping it clean. Thursday the 10th backs off to 6ft, but the period holds at 15 seconds. Friday the wind picks up to 16 knots in the afternoon, still cross-off but a bit lumpy.
The pattern holds through the second week: steady 5ft to 8ft SW swell, mostly 14-18 second periods, with cross-off winds from the SE or SSE. Energy stays in the 1300-3200 range. All clean, but marginal.
The real standout is the weekend of September 19th and 20th. Saturday the 19th, the morning swell drops to 5ft from the SSW, 14 seconds, energy 1322. The wind eases to 8 knots, still cross-off. The afternoon brings a 4ft SW swell with a 19-second period – very long period – and energy 1661. The forecast says “excellent surf conditions for experienced surfers.” On a reef, that’s a beauty. Then Sunday, September 20th, is the big one: 10ft from the SW, 16-second period, energy screaming at 4261. That’s a massive groundswell, and with light winds at 6 knots in the morning, it’s going to be clean and heavy. Expert only.
So the best call is the 20th of September – that 10ft SW groundswell with light winds. It’s a true standout. The Saturday before is a good, clean warm-up. The rest of the window is steady but nothing to get emotional about.
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.
