The Lowdown
Right, mate. Rusty here. Look, I’ve got to be straight with you – the next couple of weeks are a write-off for Zaga (Koroni). The whole 16-day window is a blank. There’s nothing on the cards that’s anywhere near worth paddling out for.
We’ve got a long stretch of near-flat conditions. The combined swell energy barely registers a whisper, with the only blips showing a paltry 1 for the combined energy of all swells directed here on the 5th of September and again on the 11th of September. That’s basically nothing. Most days the wave comment just says “poor surf conditions” because there’s no swell at all.
It’s a real shame because the offshore winds look promising at times. You’ll get some glassy mornings, like on the 28th of August, 31st of August, the 1st of September, and the 4th of September, but with zero swell, clean conditions don’t mean a thing. There are also clean offshore breezes from the NNW on the mornings of the 6th, 7th, and 9th of September, but again, it’s a flat ocean. The afternoons tend to get a bit of a cross-shore chop from the SW, but it doesn’t matter when there’s no wave to ruin.
This isn’t unusual for a spot that’s listed as “rarely breaks” and is “sheltered.” Don’t bin your board just yet – forecasts can shift, but right now, there is honestly nothing to get out of bed for. You’re better off doing something else.
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.
