The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next couple of weeks look pretty bleak for a paddle. We’re looking at a long stretch of flatness with hardly a ripple to get excited about.
Right from the start on Wednesday the 5th of August, it’s a no-go. The combined wave energy at Zaga (Koroni) is a big fat zero (0), and we’ve got a 16 mph cross-offshore wind blowing across a flat ocean. The water’s a touch warmer than normal at 81°, but that’s the only comfort here. The whole first week, from the 5th right through to the 10th, is a total write-off. There’s simply no swell, just glassy mornings and cross-off breezes that do nothing for us.
We do finally see a pulse of something on the morning of Tuesday the 11th of August. A tiny 0.3 ft swell from the SE with a period of 4 seconds—that’s short-period wind chop, not a groundswell. The energy is a pathetic 1. It’s still poor surf conditions, and the wind is cross-off from the north. Not worth paddling out for.
The pattern stays stubbornly flat. A few more of these tiny, short-period bumps pop up on the 12th of August with a 1 ft SW swell (period of 2 seconds), and again on the afternoon of the 15th of August with a 1 ft SW swell (period of 3 seconds), but the energy never gets above 3. The wind is often cross or cross-off, and the wave comment is always “poor surf conditions.” This break rarely breaks anyway, and this forecast proves it.
Honestly, there’s not a single standout session in this 16-day window. It’s a classic dead spell for the area. The only positive is that it tends not to stay this poor for long, so keep an eye on the charts—things can change. But for now, leave the board at home.
Rusty.

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.
