The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s shaping up for Porsmilin over the next couple of weeks.

First off, the water temp is sitting about average for this time of year, so nothing wild there. The outlook starts off a bit of a mixed bag, but we’ve got a couple of windows to get excited about.

The first real chance to get wet comes on Wednesday morning, September 9th. We’ve got a clean 5ft swell rolling in from the NW with a 9-second period. The wind is a light cross-offshore from the north, making for some tidy, workable conditions. Combined wave energy is moderate (555). It’s not going to blow your mind, but it’s a solid, surfable option for an intermediate. Expect some company though – crowds are possible here.

Thursday the 10th and Friday the 11th are pretty much a write-off. The swell drops right off and the wind goes onshore or on, with barely any energy in the water (84 to 299 range). Poor conditions all round.

Things pick up a little on Saturday the 12th. The morning has a bit of a WNW swell at 3ft with a long 13-second period and light wind, but it’s onshore and the combined energy is moderate (371). The afternoon gets a stronger 5ft swell from the WNW, but the period jumps to 13 seconds and the wind goes cross-onshore, making for a choppy mess. Not a good combo.

Sunday the 13th is a better bet. The morning sees a clean 6ft NW groundswell (12-second period) with a light cross-offshore breeze. Combined energy is a solid 773. It’s a proper wave, but at 6ft, it’s getting towards the top end for beginners. For the intermediate crew, it’s worth a look. The afternoon drops a little but stays clean.

After that, the middle of the week goes flat and ordinary. Small, weak swells with onshore or cross-shore winds. A bit of a lull from Monday the 14th right through to Wednesday the 16th, though Wednesday morning has a clean 3ft swell with offshore wind from the NE – surfable but very ordinary.

Now, here’s the standout. Look ahead to Sunday, September 20th. The morning delivers a clean 5ft NW swell with a 9-second period and light cross-offshore wind. Combined energy is moderate (322). Then the afternoon is the real gem: a solid 6ft WNW groundswell, long 12-second period, and a clean cross-offshore breeze. The combined energy jumps to 1023 – that’s strong, powerful stuff. This is the pick of the forecast. It’s a bit on the bigger side for beginners, but for experienced surfers, this is where it’s at. Just keep an eye on the crowds, as they’ll likely be around.

The final few days from Monday the 21st onwards look poor again, with onshore winds and messy conditions, apart from Tuesday the 22nd which has clean small waves but nothing special.

So, to sum it up: the best bet is Sunday the 20th, especially the afternoon. Wednesday the 9th and Sunday the 13th are your other solid options. The rest is mostly a write-off or very ordinary.

Rusty, signing off.

Information about the Porsmilin Surf forecast

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