The Lowdown
Alright folks, Rusty here. Let's be straight with you – the surf outlook for our little corner of the coast is a tough one. We're looking at a long stretch of quiet, with very little to get excited about.
The only spot on the radar is Zaga (Koroni), a sheltered beach and point break that's a beginner-friendly wave. The issue is, it rarely breaks, and over the next 16 days, it's barely going to flicker. The first week is a total write-off. From Wednesday, August 12th, right through to the end of the week, the swell is virtually non-existent, with combined wave energy readings sitting at zero (0) to a measly 1. The wind is mostly cross-off or light, which would keep it clean, but there's simply no swell to push through.
We do see a tiny pulse showing up on the morning of Sunday, August 16th. The swell is a weak 1 ft from the SW, with a short period of 4 seconds. The combined energy is just 7 – that's about as weak as it gets. The wind is light and cross-off, so the surface will be clean, but you'd be lucky to find a wave that breaks. It's a "poor surf conditions" call all the way.
The pattern continues into the second week. There are a few glassy mornings, like Monday, August 17th, and Thursday, August 20th, which are beautiful to look at but still flat. A tiny, 0.7 ft pulse from the SSE shows up on the afternoon of Friday, August 21st, but that's a cross-onshore wind and a 2-second period – it's barely a ripple.
Honestly, there's nothing here that qualifies as a standout. The best you could hope for is a single, weak wave on the morning of the 16th, but even that's a long shot. For a beginner, it's not even worth paddling out. For the more experienced, there's just no energy to work with.
This is a blank run, plain and simple. The good news is it tends not to stay this quiet for long, and forecasts can change, but for now, save your wax and your energy.
Rusty.

A general guide to surfing at Zaga (Koroni) can be found by selecting the local surf guide option on the grey menu. Our Zaga (Koroni) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
