The Lowdown
Alright folks, Rusty here. Let's be honest about what we're looking at for the next couple of weeks. It's a quiet stretch, that's for sure.
We're looking at Zaga (Koroni), a sheltered beach and point setup that only rarely breaks. The long-range picture is bleak, with a big gap of nothingness. The first real glimmer of any surfable energy doesn't show up until Thursday afternoon, July 23rd, and even then it's just a tiny 1 ft swell from the South with a period of 3 seconds. The combined energy is basically zero (1), so it's not going to be doing much.
The best bet in this whole 16-day window? Honestly, there isn't a standout. We get a few mornings with flat, glassy conditions, like Wednesday July 22nd, Monday July 27th, and the early sessions on August 3rd and 4th, but there's no swell to ride. The wind is often clean or offshore, which is a tease because the swell just never shows up. Later in the window, on Monday August 3rd, we see a tiny 0.3 ft SE swell, but again, the energy is minimal (1). It's a solid two-week run of poor surf conditions.
For a beginner, the complete lack of any wave height means it's not too big, but it's also not breaking. The water temperature will feel about average for the time of year at Zaga. If you're looking for paddle surfing, you are out of luck. The odd gusty afternoon with a cross-offshore breeze and flat water might be more interesting for a kiteboarder looking for a flat-water session, but for a surfer, it's a time to find another hobby or go traveling.

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. 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.
