The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the outlook for the next 16 days around Zaga (Koroni) is a bit of a bummer, to be honest. There’s just not a whole lot of swell on the table.
Looking at the forecast, the only real wave energy we see is a tiny pulse on Sunday morning, August 16th. We’re talking about a weak 1.0ft swell from the SW with a period of only 4 seconds – that’s pretty gutless, with combined energy of just 2 (2). The morning wind is a light cross-off from the NNW at 6 mph, which would keep the surface clean, but the waves themselves are just too small and weak to get excited about. The water temperature is sitting at 83°, which is a notable 4° warmer than usual for this time of year, so the water will feel like a bath.
After that brief flash, the rest of the 16-day window is a total blank. From Sunday afternoon on August 16th all the way through to Monday, August 31st, there’s zero swell energy showing up. The combined energy is a flat zero for every single session. The winds are often light and clean, with some glassy mornings, but without any waves to ride, it doesn’t matter.
Zaga is a sheltered spot that rarely breaks, and this forecast confirms it. When there’s no swell, that’s just the nature of the place. It’s a spot that needs a decent push of SSE swell to light up, and we’re not seeing that in this window. Honestly, if you’re desperate for a paddle, the Sunday morning window on August 16th is the only chance, but don’t expect much.
Rusty.

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.
