The Lowdown
G’day, Rusty here, looking at the forecast for the next couple of weeks. We’ve got a solid run of waves coming through, but it’s not all clean and perfect. The main spot on the menu is Ekas-Inside, a sheltered reef break that’s fairly consistent and suits beginners. The water temp is about average for this time of year, nothing too wild. Let’s break it down.
The pattern is a long stretch of moderate to strong groundswell, with the combined energy sitting in the strong to very strong range for most of the first week. The wind is a bit of a let-down though – it’s cross-offshore from the SSE or SE at 12 to 19 mph for the whole first week, which keeps the waves clean but not ideally glassy. The swell’s coming from the SSW or SW, with periods mostly between 14 and 18 seconds, so it’s solid groundswell with good shape. The break is sheltered, so it handles the direction well.
Starting Monday 7 September morning, we’ve got 7 ft of SSW swell at 14 seconds, but the wind is a moderate breeze from the SSE at 16 mph. It’s clean, but the energy is strong. That’s the story for the first few days – consistent wave heights around 6 ft to 8 ft, but the wind is always a bit punchy. The best window in the first week is probably Tuesday 8 September afternoon, with 6 ft of SW swell at a very long 18 seconds – that’s a proper groundswell, and the combined energy hits its strongest. It’s shaking up the reef nicely, but it’s not a standout for wind.
Thursday 10 September afternoon has a similar vibe: 7 ft of SSW swell at 16 seconds, clean, but the cross-off wind keeps it from being immaculate.
The standout for the whole period comes on Tuesday 22 September morning. That’s over two weeks away, so keep that in mind. The swell is 7 ft from the SSW with a very long period of 19 seconds, and the combined energy is strong. The wind is a moderate breeze from the SSE at 16 mph, cross-off, but the quality of that groundswell makes it the pick of the bunch. It’s a bit far out, so don’t lock it in yet, but it’s the one to watch if you love a long, powerful line off the reef.
Overall, the first week is a solid grind with good wave heights but persistent moderate winds. The second week settles down a bit, with wave heights dropping to 4 ft to 7 ft, and the energy coming down to mostly moderate. The wind finally eases to a gentle breeze on a few mornings, like Sunday 19 September and Monday 21 September, which is a nice change. Monday 21 September morning is a highlight: 6 ft of SW swell at 14 seconds, gentle breeze (9 mph), and the forecast says “expect very good surf conditions” – the calmest wind day of the whole run.
If you’re a beginner, the first week has waves between 5 ft and 8 ft, so it’s doable but a bit pushy on the bigger days. The reef is sheltered, so it’s not a washing machine, but keep your wits about you when the swell tops 7 ft. Crowds are listed as “sometimes,” so you might have it to yourself mid-week.
Rusty.
