The Lowdown
Alright, Rusty here. Let’s be straight with you – the next couple of weeks are looking like a tough stretch for anyone chasing waves around Zaga (Koroni). This is a spot that rarely breaks at the best of times, and unfortunately, the forecast is backing that up. We’re looking at a long, dry run with no real surf to speak of for the entire 16-day window.
The water is sitting at 83° – that’s much warmer than usual for this time of year, which is a real standout. You’ll be swimming in bathwater, but you won’t be surfing.
The pattern starts quiet and stays quiet. From Tuesday 25 August right through to Wednesday 9 September, there’s barely a ripple. The combined swell energy is a flat zero for most of the period, with only a couple of tiny pulses showing up. On Friday 28 August morning, we get a whisper of east swell at 0.3 ft and a 5-second period – that’s barely a bump. The combined energy reads 1 – forget about it. Then again on Saturday 29 August afternoon, a tiny 1.0 ft southwest swell with a 2-second period pops up, energy still sitting at 1. Not worth paddling out for.
The best conditions we see are glassy and clean on a few mornings, like Thursday 27 August, Monday 31 August, and Tuesday 1 September, but there’s just no swell to work with. Even when the wind goes offshore or glassy, like on Wednesday 26 August morning with a gentle WNW breeze, there’s nothing to ride.
To be honest, this setup looks more interesting for a kite surfer than a paddle surfer on those rare occasions when the wind picks up – like Wednesday afternoon 9 September with a 12 mph cross-onshore and a risk of thunderstorms, but even then, the swell is pathetic.
There’s no standout day here. No best on offer. This is a total blank. Zaga (Koroni) is a sheltered, inconsistent spot, and when the charts are this empty, it’s just a waiting game. Forecasts 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.
