The Lowdown
Alright, this is Rusty. Let’s be straight with you – the outlook for the next 16 days at Zaga (Koroni) is a real heartbreaker. The whole period is flat, with no rideable swell to speak of. We’re looking at a long, dry run from Friday the 31st of July all the way through to Saturday the 15th of August with nothing but tiny dribbles and no energy. The combined energy of all swells directed here is a measly 1, so the ocean is basically asleep. The water temp is sitting at 80°, which is about average for this time of year, so no surprises there.
The first sniff of anything on Friday the 31st morning is a pathetic 0.3 ft from the SE with a period of only 4 seconds – that’s pure wind chop, not surf. The wind is light and cross-off from the north, so the surface is clean, but there’s simply nothing to ride. That afternoon gets worse with a cross-on breeze from the SSW at 9 mph, making the water choppy and messy. The next few days are a carbon copy: Saturday the 1st of August morning has a clean 1.0 ft from the SSW at 2 seconds – that’s barely a ripple. Sunday the 2nd sees a similar 1.0 ft from the SW at 3 seconds. The wind varies from glassy calm to light offshore, but it doesn’t matter because there’s no swell.
Monday the 3rd of August morning is actually glassy, with 3 mph from the NNW, but the wave height is a dash (–), meaning no surf. This pattern continues day after day. There are several mornings with glassy conditions and offshore winds – like Tuesday the 4th, Wednesday the 5th, Thursday the 6th, Friday the 7th, Saturday the 8th, Sunday the 9th, Monday the 10th, and even a dead calm on Tuesday the 11th of August morning – but always with zero swell. The afternoons are mostly clean with light to moderate cross-off breezes from the west, but the ocean is just a flat lake.
This break is listed as "rarely breaks" and it’s living up to that reputation. For a beginner-friendly spot, this is a tough stretch. If you’re looking for a paddle, you might find some glassy water for a swim, but for surfing, there’s nothing. The setup is a sheltered beach and point, so when there is swell, it needs a specific SSE direction to work, but that’s not happening in this window. For a kite surfer, the consistent afternoon cross-off winds from the west at 9-16 mph could be interesting, but for a surfer, it’s a blank run. This is normal for the area – it tends to go quiet like this, and forecasts can change, but right now, there’s not a single day worth paddling out.

Information about the Zaga (Koroni) Surf forecast
The above surf forecast table for Zaga (Koroni) provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
