The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our little corner of the coast.
Right off the bat, we’ve got a bit of a slow start. The first real sniff of action is this Sunday morning, the 13th of September, but honestly, it’s small. We’re talking clean, glassy conditions at Plentzia with a 4ft NW swell pushing in with moderate energy (546). The water is sitting at 72°, which is a touch warmer than normal for this time of year – a nice little bonus. However, this spot is sheltered and rarely breaks, so it’s not exactly a pump. The ESE offshore is a major positive, making for clean faces, but the swell is just too weak to get excited about. That afternoon, the wind swings NE, keeping it cross-off and clean, but it’s still very average.
Monday the 14th is much the same story – small NW swell, around 4ft, with clean conditions in the morning from an offshore ESE breeze, but the energy drops off quick. By the afternoon, it’s barely a ripple.
Then we hit a dead spot. From Tuesday the 15th right through Friday the 18th, things go pretty flat or onshore. Tuesday sees the wind howling onshore from the WNW, and the swell turns into a messy, short-period 5-second windswell. That’s not surfing, that’s a washing machine. Wednesday and Thursday are cross-on and choppy, with the combined energy stuck in the weak-to-moderate range. Friday morning is just as forgettable. It’s a rough few days.
But hold on. The real standout of this whole outlook is Saturday the 19th of September. This is where it gets interesting. We’ve got a solid 7ft NW groundswell rolling in, with a nice long 13-second period. The combined energy jumps right up to 1502 – that’s strong, powerful stuff. And the wind? Glassy offshore from the ESE in the morning, shifting to a light cross-off from the NE in the afternoon. This is going to be clean, lined-up, and punchy. This is the day to be in the water. It’s a bit too big for beginners, but for anyone with a bit of experience, this is the pick of the fortnight. The direction is a touch off the optimum WNW for the spot, but with that size and period, it’ll still wrap in nicely.
Sunday the 20th is still very good – another 7ft NW swell with 12-second period and light offshore wind in the morning. The energy is still huge (1403). It’s a close second, but Saturday just edges it out with that glassy morning.
After that, the quality starts to fade. Monday the 21st has the biggest swell of the run (7ft, 14-second period, energy 1811), but the wind goes onshore from the WNW, killing the quality. That’s a shame – it’s a beast of a swell but blown out. Tuesday the 22nd improves a bit in the afternoon with a cross-off, but it’s not the same.
We get another clean window mid-week: Wednesday the 23rd morning is glassy with a 5ft NNW swell – a solid, clean option with decent energy (734). Thursday the 24th is smaller and more ordinary, but still glassy in the morning.
Later in the outlook, Friday the 25th of September morning shows another promising window. A 6ft NNW groundswell with a 13-second period and light cross-off wind from the SSE. Energy is strong at 904. This is another good morning, but the afternoon turns cross-on and gets a little wind-affected.
The final weekend, the 26th and 27th, looks messy. Saturday gets a cross-on breeze and some rain, and Sunday is blown out by stronger ENE winds. Not worth paddling out for.
So, to sum it up: there’s a bit of a flat spell mid-week, but the real highlight is Saturday the 19th of September – big, clean NW groundswell with offshore winds. Don’t miss it. The 20th and the morning of the 25th are also solid secondary options.
Stay stoked,
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.
