Right, gather ‘round. Rusty here. Let’s have a look at this stretch of coast.
Straight up, I’m looking at the forecast for the next sixteen days and I’ve got to be honest with you – it’s a bit of a blank wall. The run of swell we’re hoping for just isn’t in the cards. After the 19th of August, there’s nothing but flat, calm conditions right through to the 3rd of September. That’s a solid two-week gap with no surf to speak of.
The only spot on the map is Zaga (Koroni). It’s a sheltered beach-and-point number that rarely breaks, so this kind of dry spell isn’t a total shocker for this area. The water is sitting at 83°F which is much warmer than normal for this time of year, so at least it’s nice for a swim.
The combined swell energy is a flat zero (0) the whole way through. There’s simply no wave energy to work with. The winds are often glassy or offshore, especially on the mornings, which would be a dream if there were any waves, but with no swell, it’s just a pretty, flat ocean.
For the first few days, we’ve got clear skies and calm winds, but the swell is a total no-show. That’s the story, I’m afraid. There’s absolutely nothing to get excited about. I wouldn’t bother waxing the board for a while.
Keep an eye on the long-range forecasts though – it tends not to stay this flat forever.
Rusty.
