The Lowdown
Right then, let’s have a look at what’s on offer here. I’m Rusty, and I’ve been staring at the charts for Plentzia. First thing you need to know – the water is running at 75°F right now, which is much warmer than normal for this time of year, so that’s a nice little bonus if you’re heading out.
Honestly, the outlook is a bit of a slow burner. We’ve got a long stretch of poor conditions coming up. The first decent surfable window doesn’t appear until the morning of Saturday the 22nd of August. Before that, it’s a write-off – small, weak, and messy.
The Saturday the 22nd morning session offers some hope. It’s not big, with a 4ft swell from the NW, but the wind is cross-offshore and the conditions are clean. The combined wave energy is moderate (206). It’s surfable, but it’s ordinary. That afternoon, the swell drops and the wind picks up, so that morning is your best bet for the weekend.
The next real standout, the one worth circling on the calendar, is the morning of Friday the 28th of August. The wind goes light offshore from the ESE, and the swell is a solid 5ft from the NW, with a period of 10 seconds – that’s a proper groundswell with some punch. The energy is strong (530), and the report says to expect good surf conditions. This is the pick of the forecast. The water will still be warm, and the waves will be clean. For a spot that rarely breaks, this is a golden opportunity.
Following that, the morning of Wednesday the 2nd of September is another glassy morning. The swell is 7ft from the NW, but with a period of 8 seconds, it’s a bit more of a wind swell. Still, with glassy conditions and a strong energy reading (582), it’s promising, but it’s over a week away, so it’s a more distant prospect.
There’s a big swell coming through on Monday the 31st of August with 10ft waves and very strong energy (1695), but the wind is cross-onshore, and the report calls it marginal. That’s a washing machine for the experts. For the rest of us, the Friday the 28th morning is the one to aim for.
Crowds at Plentzia can be an issue, so get in early.
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.
