The Lowdown
Alright folks, Rusty here. Let's be straight with you – the outlook for the coming two weeks is a quiet one. The water's sitting at a warm 81°, which is a touch warmer than normal for this time of year, but that's where the good news ends. We're staring down a long dry spell with barely a ripple to get excited about.
The first hint of any real swell doesn't show up until Friday the 14th of August, and even then it's just a whisper. Before that, from now through to Thursday the 13th, there's absolutely nothing. The combined wave energy is a flat zero (0). It's a full week of clean, glassy mornings but with no waves to ride, so don't bother paddling out.
On Friday afternoon the 14th, we finally see a tiny pulse of 1ft swell from the southwest, with a period of a measly 2 seconds and combined energy of just 1. It's a poor surf condition, and definitely not worth the drive. The rest of that weekend stays quiet too, with similar tiny, weak swells showing up on Saturday the 16th – a 1ft SSW swell with a 3-second period and energy of 3. Again, it's labelled as poor surf.
Then from Sunday the 17th of August all the way through to Monday the 24th, it's a complete blank. Zilch, nada, zero energy. The winds are off and glassy at times, especially on the mornings of the 17th, 20th, and 21st – perfect conditions for a flat, mirror-like ocean.
So, the honest truth is there are no standouts, no good options in this 16-day window. Zaga (Koroni) is a sheltered spot that rarely breaks even in the best of times, and this forecast confirms it.
Rusty.
