The Lowdown
G’day, Rusty here. Let’s talk about Ekas-Inside for the next couple of weeks. The whole run is surfable but nothin’ special – all of it comes in with a cross-off wind that keeps the surface from goin’ glassy. Water temp’s 80°, pretty average for the season.
The first waves show up Sunday afternoon, the 30th of August, with a clean 5ft swell from the SW, period of 13 seconds. Energy’s moderate (1367), but with a 15 km/h SE cross-off breeze, it’s got a bit of texture. It’s a beginner-friendly reef, so you can get into it. Through Monday and Tuesday, the swell builds to 7ft by Tuesday morning (1st September), with a long 18-second period and moderate energy (2843). The cross-off breeze holds at 25 km/h, so not glassy, but the 7ft with that period means good shape.
By Wednesday the 2nd, we’ve got steady 7-7ft swell with 16-17 second intervals, energy still solid (up to 2471). Wind stays cross-off from the SE at 25-30 km/h – a bit breezy but workable.
The swell drops Thursday and Friday (3rd-4th) to 4-5ft, periods shorten to 14-16 seconds, and energy falls below 1000 by Friday morning. Friday afternoon gets messy with 30 km/h wind. Saturday the 5th lifts again to 6ft from the SSW, 16-second period, moderate energy (1629), but that cross-off stick around.
The real juice comes Tuesday the 8th to Thursday the 11th of September. We’ve got 7-8ft SSW groundswell, periods of 16-19 seconds. Energy goes big: Tuesday afternoon hits 4459, Wednesday morning reaches 4954, and Wednesday afternoon tops out at 5824 – that’s strong-to-very-strong power. Swell direction lines up perfect with the reef’s optimum. Wind is cross-off from the SSE at 20-25 km/h, which keeps it reasonably clean. That 8ft at a reef with long period is expert territory – you’ll get big, fast sets. Crowds are only sometimes a problem, so you might have company but not a zoo.
After that, the swell fades into the second week. Saturday the 12th holds at 7-7ft, still okay, but by Sunday and Monday (13th-14th), we’re back to 5-6ft with 14-16 second periods and energy in the 1400-1900 range. Wind stays cross-off at 20 km/h. It’s still surfable but nothing special.
The clear standouts are Tuesday the 8th through Thursday the 11th – that’s the best size and power in the whole window for anyone comfortable in big, long-period waves. The rest is just consistent but average.
Rusty.
