The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the outlook for the next couple of weeks is about as flat as a pancake. I’m looking at a long stretch of virtually no surf energy hitting our shores. We’ve got a real gap on our hands here, with barely a ripple to get excited about.
Looking at Zaga (Koroni), the place is a sheltered beach and point setup, and it rarely breaks as it is. The first couple of days are a write-off. Monday the 14th and Tuesday the 15th serve up poor conditions with no real swell to speak of, and on Tuesday afternoon we might see a tiny 3 ft from the ESE, but the period is a short 5 seconds and the wind is messy cross-onshore, so it’s choppy and not worth a paddle. The water temperature is sitting at 84°, which is much warmer than normal for this time of year – a real anomaly, over three degrees above average.
From Wednesday the 16th right through to the end of the month, it’s a dead run. The combined energy figures are sitting at zero or 1, which tells you everything. We get a few moments of clean, glassy conditions with light offshore winds, like on Saturday the 26th morning with a glassy NW breeze, but with no swell height to speak of (0.3 ft), it’s flat calm. The occasional tiny pulse of 0.3 ft to 1 ft from the SE with a weak period won’t even tickle the inside shore.
Honestly, there are no standout days. The wind might be kind now and then, but without swell, it’s a no-go for surfing. This is a long blank spell. If you’re a kite surfer, you might find the stronger winds later in the period, like the 19 mph WNW on the 29th, more interesting for some fun on the water, but for a paddle surfer, it’s a stretch of empty horizons.
Keep the board in the car, but don’t hold your breath. Forecasts can change, but right now, it’s a waiting game.
Rusty.
