The Lowdown
Alright folks, Rusty here. Gotta be straight with you on this one. Looking at the charts for our local stretch, it's a pretty grim 16-day window. There's a big fat zero on the energy scale for the whole run, so we're not talking about a quiet spell – we're talking about a flat spell. The first hint of any ripple doesn't show up until the very end of the month, and even then it's barely a whisper.
So, let's call it what it is: a solid two-week gap with no surf to speak of. From now until the 27th of August, you're looking at a lake out there. The water is a balmy 83°F right now, which is much warmer than usual for this time of year, but that’s little comfort when there's no waves to enjoy it in.
The only spot we've got to look at is Zaga (Koroni). It's a sheltered beach and point setup, but it *rarely breaks* anyway, so this blank run is pretty normal for the area. The optimum swell direction is from the SSE, and we just don't have any of that.
Now, on the 27th of August, Thursday afternoon, we finally see a pulse. It's tiny. A 1 ft swell from the south with a short period of 2 seconds. The combined energy is a measly 2 (two). That's not a wave, that's a ripple. The wind will be offshore from the WNW, which is clean, but it doesn't matter when there's nothing to push. Even on the 28th and 29th, the wind stays offshore, but the swell is still a no-show.
There is no standout session here. For the whole 16 days, there is nothing worth paddling out for. If you're desperate for a float, the glassy mornings on the 19th, 20th, 24th, and 1st of September will be pretty, but they'll be flat. The best you can hope for is a long walk on the beach.
Stay tuned, forecasts can change, but right now, it's a hard pass.
