The Lowdown
Right then, let’s have a look at what’s on offer around here. To be honest, it’s a pretty quiet stretch ahead. The forecast shows a whole lot of nothing for the next week and a half, with only a tiny flicker of life right at the end. The water is sitting at a balmy 84°F, which is a solid 6°F warmer than usual for this time of year – that’s weirdly warm, even for the Med.
The first real chance of a wave comes in on the morning of the 8th of September. We’re talking about Zaga (Koroni), a beach and point set-up that’s sheltered and rarely breaks, so this is a noteworthy event. It’s a tiny 0.3ft SE swell, with a period of 4 seconds. The combined energy is basically nothing (1), so it’s not going to get your heart racing. The wind is glassy though, so if you’re a beginner looking for a dribble, it’ll be clean. The morning of the 9th of September is also glassy, but dead flat.
The next whisper of swell shows up on the afternoon of the 14th of September. A 1ft SW swell with a period of 3 seconds and combined energy of just 3. It’s still poor surf conditions, with a cross-shore wind, so it’ll be a messy, weak little wave. Not much to get excited about at all.
The 16th of September has a 0.3ft SE swell with rain showers and a cross-onshore wind, which is just a write-off. Then, the rest of the window through to the 19th of September offers nothing but flat spells and clean but waveless mornings. There’s simply no standout, no good option in the entire 16 days. For a spot that rarely breaks, a blank run like this is pretty normal. It’s a tough one, but forecasts can change. Keep an eye on it.

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.
