The Lowdown
Right, let’s have a look at what we’ve got for the Zaga (Koroni) stretch. I’m Rusty, and I’ll be straight with you – this forecast is a tough one.
Over the next 16 days, from the 26th of August right through to the 10th of September, the swell is virtually non-existent. The combined energy of all swells directed here is a flat 0 for most of the period, briefly bumping up to a weak 1 or 2 (and once to 4) – that’s barely a ripple. There’s a massive gap of no surf worth paddling for. The first sign of any waves is on the morning of Saturday the 29th of August, with a tiny 0.7ft swell from the ESE, but it’s cross-onshore and has a period of just 4 seconds. That’s not going to get you out of bed.
The water temperature is a notable 84°F at the start, which is much warmer than average for this time of year, but honestly, you’ll be floating in it more than surfing it.
The only break on offer, Zaga (Koroni), is a sheltered beach and point that rarely breaks. For a spot to be this inconsistent and still have no real swell, it’s a dead period. The best you’ll see is a few 1ft to 1ft waves on the 29th and 30th of August, with periods around 3 to 4 seconds – that’s pure wind chop, short period and weak. There are some glassy mornings, like the 27th of August, but with nothing to ride, it’s just a pretty view.
If you’re a beginner, the tiny size might not be intimidating, but the lack of any decent push means there’s nothing to catch. For everyone else, this is a flat spell. The conditions look more interesting for a paddleboard or a flat-water session than a surf. Honestly, I’d check back in a week – forecasts can change, and it tends not to stay this poor for long.

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.
