The Lowdown
Right, folks, Rusty here. Gotta be straight with you – this next couple of weeks is looking like a write-off for a proper paddle. Let’s get into it.
We’re starting off with nothing really on the cards. The first glimmer of anything half-decent doesn't show up until Monday the 14th of September, but even then, it’s a weak 2.6ft W swell with a short period of 10 seconds at Plemont. The wind is light and cross-offshore, so it’ll be clean, but the wave energy is pretty weak (117). It’s surfable if you’re absolutely desperate for a splash, but I wouldn’t get the hopes up. The water’s sitting around 66.6°, which is much warmer than usual for the time of year – a real anomaly that’s more than 4.5° above the norm, so you can leave the steamer at home for this one.
The pattern just doesn’t improve. Tuesday and Wednesday get blown out by cross and cross-on winds, with the swell staying small and messy. There is a bump in energy on Wednesday the 16th with a 4.9ft W swell and a moderate combined energy of 677, but it’s all for nothing with a strong cross-onshore wind making it lumpy and poor. That theme continues – plenty of swell on Thursday the 17th (5.2ft, 504 energy) but the wind is howling, making it a total mess.
We hit a dry patch from the 19th through the 24th, with most days offering nothing but poor conditions. The only note is Monday the 21st of September, where we see a long-period groundswell from the WNW, 14 seconds, but it’s only 2.6ft. The combined energy is moderate at 253, and the wind is light and cross-offshore, so it’ll be glassy clean. For a spot like Plemont, which is an exposed beach, that long period might make it break a bit too straight, but if you’re after a really clean, small-wave session, that’s your best bet. It’s also inconsistent, so you’ll be waiting around.
After that, the forecast goes totally flat and blown out right through to the 28th. The energy drops right off, and we’re looking at tiny, short-period slop and fresh winds. Honestly, for this region, you’d be better off finding a kite if the wind’s your thing, because for a paddle surfer, there’s nothing to get excited about for the rest of the period.
Stay patient, lads. It’ll turn around eventually.

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