The Lowdown

Alright, Rusty here, and I’ve got the goods on the local surf outlook for the next couple of weeks. We’re looking at Plentzia, and I’ll be straight with you—it’s a bit of a slow burn, but there’s a real gem waiting if you’ve got the patience.

Right now, we’re in a pretty flat spell. The first real surf we’ll see is a tiny pulse on Thursday the 20th, with a 4ft swell from the NW, but it’s got a long period of 11 seconds and the combined energy is moderate at 303. The wind is that light cross-onshore, so it’s not going to be pretty. Expect poor surf conditions. That’s the start of a stretch of small, messy waves—nothing to get excited about through the 21st and 22nd, where we get a bit more size (up to 5ft on Friday morning) but the period is short and wind is onshore, making it mostly a write-off.

Then we hit a quiet patch. From Sunday the 23rd through to the 27th, it’s all small, weak swells with poor quality. The wind is mostly cross or onshore, a few glassy moments, but the swell is just too small. It’s a real testing period for the soul.

But hold on. The real standout, the one you’ve been waiting for, is on Friday the 28th of August. We’ve got a solid 6ft swell from the NW, with a very long period of 12 seconds, and the combined energy is strong at 869. The wind is glassy—absolutely dead calm. That’s the kind of morning that makes you forget the flat spell. The swell direction is pretty much on the money for the break, and with that long period, it’s going to have some proper power and shape. For a beach break, a period over 11 seconds can mean it breaks a bit straight, but with that glassy surface, it’s going to be clean and fun. This is the best on offer, no question.

Then, on Monday the 31st, we’ve got another big pulse. The morning brings a 7ft swell from the NW, short period of 8 seconds, but the combined energy is strong at 694 and the wind is glassy again. That’s a lot of water, and it could be a bit much for beginners, but for the experienced crew, it’s going to be a fun, punchy session. The afternoon is the real headline: a 4ft swell from the NW with a very long period of 16 seconds, and the combined energy is very strong at 1419. The wind is light cross-offshore, making it clean. This is a long-period groundswell, and at Plentzia, it’s going to offer some really nice lines. It’s a standout session.

Into Tuesday the 1st of September, we’ve got a 8ft NW swell with a 14-second period—very strong energy at 2323. The wind is light cross, so it’s going to be a big, powerful day. With that size, it’s only for experts. The afternoon gets messy with onshore wind, so get out early.

The water temperature is 76°, which is 5° warmer than usual for this time of year. That’s a notable anomaly, so it’s feeling like a warm bath out there.

Alright, that’s the picture. The glassy mornings on the 28th and the 31st are the real standouts. The rest is a waiting game. This is Rusty, signing off.

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.
