The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this is a tough one to write. We're looking at a long, dry spell with barely a ripple for the next couple of weeks.
The entire 16-day window for this region is basically a bust. From the start of September right through to the 15th, there's absolutely no swell to speak of. Zero energy. It's flat, flat, flat. The winds are often clean or even glassy, which would be a dream if there was any wave, but there just isn't. We're talking a full two-week gap with no surf on offer.
Now, the only break on the map is Zaga (Koroni) , a sheltered beach and point. It’s a spot that rarely breaks anyway, which fits the bill here. Things get a tiny bit of life right at the very end of the forecast window. On the morning of Thursday, September 16th, we might see a tiny pulse of swell, with a combined energy of just 2 (weak) , coming in at a pathetic 0.3 ft from the southeast with a short period around 4 seconds. The wind is light and cross-off, so it would be clean, but it’s barely a ripple.
The afternoon of the 16th brings a slightly bigger pulse of 0.7 ft from the SSE, but with a moderate cross-shore breeze that would chop it up. Even so, the combined energy is only 4 (weak) . To be honest, if this is all we’re getting, you'd be better off taking up kiteboarding if it picks up any more wind because for a paddle surfer, this is a total write-off. The morning of the 17th looks glassy but with only 0.3 ft on offer again, the energy is just 3 (weak) .
There are no standouts here. The only honest thing I can say is that for Zaga, this kind of blank run is pretty normal. Forecasts can change, but for now, plan on a lot of flat spells.
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. If you surf the same spot (Zaga (Koroni)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
