The Lowdown
Alright crew, Rusty here, giving you the straight up on what’s happening at Zaga (Koroni) for the next couple of weeks.
Gotta be honest, it’s looking grim. We’re staring down a long stretch of nothing. The first time we see any kind of bump in the water is not until the 11th of August, and even that’s a joke.
The water is about 81°F, which is a touch warmer than usual for this time of year, but that’s about the only good news.
Starting Thursday the 6th of August, it’s a zero score with poor surf conditions. From Friday the 7th through Tuesday the 10th, it’s the same story over and over: clear skies, no swell, and a combined wave energy of zero. It’s a glassy, flat ocean with a light breeze.
On Tuesday the 11th of August, we finally get a tiny pulse. A 0.3ft swell from the SE with a period of just 4 seconds. The combined energy is a measly 1. The wind is cross-offshore from the N at 15 mph, so the surface is clean, but there’s nothing to ride. The afternoon is flat again.
The 15th of August, Saturday afternoon, shows a 1ft swell from the SW with a 2-second period and combined energy of 1. The wind is light cross-off from the WSW at 3 mph, leaving it clean. But a 2-second period is just wind chop, not a real wave. Still poor surf conditions.
From the 17th of August on, we get some glassy mornings, especially the 18th and 20th, with offshore or glassy winds from the NNW or NW. But there’s zero swell. The afternoons bring a cross-shore wind from the SW, stirring up a little chop on a flat ocean.
The best of a bad situation? If you just want to get wet, the morning of the 18th of August (Tuesday) is glassy with a light NNW breeze, but the swell is a flat zero. The 15th of August afternoon has the biggest wave of the whole forecast at 1ft, but with that 2-second period, it’s just messy. There’s no standout here. This is one of those blank runs that happens when the swell just doesn’t show up. It’s normal for the area.
Rusty, out.

A general guide to surfing at Zaga (Koroni) can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Zaga (Koroni) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
