The Lowdown
Alright folks, it’s Rusty here with a look at what’s coming up for Porsmilin over the next couple of weeks. It’s a bit of a slow start, so don’t rush out the door just yet, but there are a couple of absolute crackers hiding in the second week if you’ve got the patience.
The first few days are a write-off, honestly. We’ve got a messy onshore wind from the SW and W blowing through Thursday and Friday, with the swell sitting around 5ft to 5ft but short period, only 8 seconds, and choppy as hell. The water temp is a normal 63°, nothing weird there. Keep your board in the car for now.
The first real sign of life comes Saturday morning, the 5th of September. The sky clears, wind swings light from the E, and we get a nice 7ft swell from the WNW with a proper long period of 13 seconds. That’s a serious groundswell pushing through. The winds are cross-off, leaving it clean. This is a standout session for the first week – the best on offer. That long period will make for some nice lines wrapping into the sandbar, but it might be a bit much for beginners at that size.
Saturday afternoon drops off a touch in quality, and Sunday the 6th goes flat and messy again. Monday the 7th picks back up with a 7ft swell from the W, period 12 seconds, and a clean cross-off wind from the NW. The energy is high, but the forecast has a red flag on it for marginal conditions. It’s a solid surf, but you’ll need to know your tides.
The next few days after that are a bit of a mixed bag of wind and chop, nothing special until the following week. There’s a solid gap of mediocre, onshore slop with some okay-looking but not firing windows.
Now, the real gold is in the second week. Tuesday the 15th of September morning is where it’s at. We’ve got a 4ft swell from the WNW with an extra-long period of 18 seconds. That’s a very long groundswell. The wind is offshore from the NE, moderate but clean. It’s glassy, clean, and there’s heaps of energy. The report says it’s excellent for experienced surfers, and that’s spot on – that long period will be a dream on this sandbar, giving you long, clean walls. The water temp is still normal.
Tuesday afternoon and Wednesday the 16th of September morning are also standouts, with the swell holding at 7ft and a period of 14 to 17 seconds, and clean, light winds. The energy is massive. This is the best stretch of the whole forecast. The swell is getting big, so this is only for the crew who know what they’re doing.
After that, it slowly fades out through the 17th and 18th, with the swell dropping and the wind turning onshore.
So, if you’re keen, the best bet is Saturday morning the 5th for a solid, clean session, or hold out for the dreamy conditions on Tuesday the 15th and Wednesday the 16th. The crowds are sometimes an issue here, so keep that in mind. For this stretch, the sandbar at Porsmilin is the only spot in town worth talking about.
Stay stoked.
Rusty.

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.

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.
