The Lowdown
Alright folks, let’s talk Zaga (Koroni). Looking over the next 16 days, and I’ve got to level with you – it’s shaping up to be a real dry spell. This spot is a sheltered beach and point that rarely gets going, and the forecast is living up to that. We’re talking a big ol’ gap from Sunday the 13th all the way through Monday the 28th of September with basically nothing on offer.
The closest we come to a ripple is on Tuesday morning the 15th. You’ve got a tiny 1ft swell out of the ESE with a period of just 3 seconds – that’s pure wind chop. The combined energy is a measly 2. Wind is light and cross from the ENE, so it’s clear, but there’s just no power behind it.
The next slight flicker is Thursday the 17th: a 2ft swell from the SSE with a 7-second period, and the energy only climbs to 34. Still very weak. The morning wind is light cross-off from the NNE, making it as clean as you’ll see, but you’d be scratching for any kind of rideable wave.
The water is sitting around 84°F, which is nearly 7°F warmer than average – that’s a huge anomaly. Feels like you’re surfing in a warm bath.
Honestly, there’s no standout session here. It’s a flat outlook for a break that’s known for being inconsistent. This kind of quiet stretch is pretty standard for the area. Forecasts can change, but for now, don’t plan a trip around it.
