The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for the next 16 days at Porsmilin.
Right off the bat, it's a bit of a slow start. The first few days are looking pretty average, with messy winds and choppy conditions. The water temp is sitting around 64° which is bang on normal for this time of year, so no surprises there.
The first real glimmer of hope comes on Saturday morning, 5th September. That's the standout. The swell is pushing 6 feet from the WNW with a solid 11-second period, packing a decent amount of energy (780). The wind is a cross-off from the north at 9 mph, which is gonna keep things clean. Porsmilin is a sandbar and it's fairly consistent, so you should get some proper waves. The swell direction is a touch west of the optimum SW, but it's still close enough to work. This is the one to circle.
Saturday afternoon drops off a bit, and then Sunday is just small and ordinary. After that, it's a long dry spell. From Monday 7th right through to Saturday 12th, it's all small, weak, or just plain messy. There's a day or two with clean wind but barely a ripple. The energy dips right down into the double digits, not worth paddling out for.
Next up, there's a potential comeback on Saturday morning, 12th September. The swell is only 3 feet from the W with an 8-second period, weak energy (164), and light cross-off wind from the east at 6 mph. It's clean, but it's not going to get the heart pumping. Same story on Sunday 13th. The swell is small and the period is short, even though the wind is offshore from the NNE, which is a rare treat. Still, it's not enough to get excited about.
The rest of the run into the middle of the month is flat and forgettable. Glassy mornings but no juice. The wind stays light or cross-onshore, and the swell just doesn't have the size or power.
So, to sum it up: Saturday morning 5th September is your best bet. Clean, solid 6-foot WNW swell with a nice long period. If you can't make that, you're chasing scraps. The rest of the window is mostly a waiting game.
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. 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.
