The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Ekas-Inside over the next couple of weeks.
We've got a solid run of surf coming up, starting right from Tuesday the 4th of August. The pattern is a consistent, long-period SSW groundswell that hangs around for most of the period, building in size mid-week and then delivering some serious size later on. The water temperature is sitting at 79.3°, which is spot on average for this time of year, so no wetsuit worries.
Tuesday morning the 4th kicks it off with clean 5.6ft waves from the SSW with a 14-second period. The combined energy is already pumping at 1494 (moderate energy), and with a gentle cross-off breeze from the SE, conditions are looking very good. This is a solid start for a beginner-friendly reef break, but it's worth noting that while it's fairly consistent, crowds are a possibility here sometimes.
The swell builds through Wednesday and Thursday, getting up to 6.9ft by Thursday morning with a 17-second period, pushing the energy into the strong range (2691). The wind stays cross-off, keeping the surface clean, but the wave comment suggests tide conditions could be a factor.
Friday the 7th of August is the standout. The morning session is offering 7.9ft of clean, long-period SSW swell at 17 seconds, with energy hitting 3334. The wind is a gentle cross-off from the ESE. The report calls it excellent for experienced surfers, and with that size, it's definitely a step up – this is getting into the territory where only the more experienced crew should be paddling out.
Saturday the 8th holds similar size at 8.2ft, but the wind is a bit stronger. The swell keeps rolling through the weekend, with Sunday the 9th seeing 7.2ft but a freshening breeze.
The real juice arrives on Monday the 10th of August. The morning is 4.9ft from the SSW but with a very long 19-second period. The afternoon, however, jumps to a massive 9.8ft from the SSW with an 18-second period, and the energy rockets to 4940 (very strong). That's a big, powerful, long-period groundswell. This is expert territory only – way too big for beginners. The long period will make for some proper, heavy lines at this reef, but the wind is a moderate cross-off. Tuesday the 11th doesn't let up, with 9.8ft holding and energy climbing to 5250 in the morning and 6322 in the afternoon. This is a serious stretch of big swell.
After that, the swell drops back through the middle of the week. Wednesday the 12th sees 6.2ft, and Thursday the 13th of August offers another very good morning with 5.9ft and a gentle 9 mph cross-off. The energy is moderate at 1866.
The second week continues with a mix of conditions. There's a notable pulse on Saturday the 15th of August with 7.9ft from the SSW and a 17-second period, energy hitting 3805, but the wind is getting up to a fresh 22 mph in the afternoon. It's still clean, but that wind is strong. The swell then gradually fades into the 4.6ft to 4.9ft range by Monday the 18th and Tuesday the 19th, with a final late surge on Wednesday the 19th of August, seeing 7.5ft in the morning and a massive 9.8ft in the afternoon with energy at 6388. That's the biggest energy reading of the whole run, but it's a long way out so the exact timing is a bit less certain.
The best of the best is Friday the 7th of August morning, with that excellent combo of size, clean conditions, and light wind. The second standout is the big swell window from Monday the 10th to Tuesday the 11th, but that's only for the experts. For the more mellow surfer, the very first morning on Tuesday the 4th of August is a ripper.
