The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Zaga (Koroni).
Right off the bat, I gotta be straight with you – the next 16 days are looking pretty grim for paddle surfing. We’ve got a long dry spell ahead. From now, starting on the 12th of August, right through until the 27th of August, it's mostly flat with just a tiny blip of swell that’s not worth getting wet for.
The first real sign of anything is a tiny pulse on the morning of Saturday the 15th of August. We’re talking a 0.3ft swell from the SE with a period of 4 seconds. The combined energy is next to nothing at 1, so you’d be floating more than surfing. Then on the Sunday morning, the 16th of August, we see the best of a bad bunch: a 1ft SW swell with a 4-second period. The combined energy is still super weak at 7. It’s small, weak, and short-period. The wind on Sunday morning is light and cross-offshore from the NNW, so it’ll be clean, but there’s just no power in the water.
Because Zaga is a sheltered spot that rarely breaks, this run of flatness is honestly pretty normal for the area. The water temperature is about 83°, which is much warmer than usual for this time of year.
There’s a whole bunch of days with good offshore and glassy winds – like Thursday the 20th and Monday the 24th – but without any swell, it’s just a pretty lake. If you’re desperate for a splash, the tiny 1ft on Sunday the 16th is the only thing approaching a wave, but it’s strictly for the floaty board or a beginner wanting to practice pop-ups on knee-high mush.
Honestly, this setup looks more interesting for kite surfing than paddle surfing, given the consistent cross-offshore breezes and zero wave energy. Save your energy, keep the board in the car, and don't get your hopes up.
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.
