The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this forecast for Plentzia is a tough one to write. For the first ten days or so, there’s basically nothing worth paddling out for. The charts are showing a lot of weak, short-period swell and onshore junk, so don’t bother checking the cam until we get into the first week of September.
The water right now is a whopping 75°F, which is 5°F warmer than usual for this time of year. That’s a real treat, like a warm bath, but you won’t be enjoying it much with the poor quality on offer.
We’ve got a long stretch of flat to junky conditions. Thursday the 20th through to at least Saturday the 29th of August is a write-off. The swell is small, the wind is mostly cross or onshore, and the energy is weak. There’s a brief moment on Sunday the 30th of August morning where it goes glassy and the swell is 4ft from the NW, but the energy is still just moderate (287) and the ride is described as "surfable but very ordinary." Not a stand-out.
The only real glimmer in this whole 16-day window comes on Tuesday the 1st of September. The morning session is your best bet. We’re looking at a clean 6ft NW swell with a solid 11-second period. The wind is light and cross-offshore from the south, keeping the surface glassy. The combined energy is a strong 671, meaning there’s some proper push behind it. This is a decent groundswell. The direction (NW) is a bit off the optimum WNW for the spot, but with clean conditions and that period, it’ll shape up alright. After that, the wind swings onshore again in the afternoon and the quality drops.
So, the long and short of it: you’ve got a big gap of nothing, then a promising but short-lived window on the morning of the 1st of September. The rest of the outlook is a hospital pass for surfers.
Rusty.

Information about the Plentzia Surf forecast
The above surf forecast table for Plentzia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Plentzia can be found by selecting the local surf guide option on the grey menu. Our Plentzia 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 (Plentzia) 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 Plentzia 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.
