The Lowdown
G’day, it’s Rusty here.
Let’s be straight with you—this 16-day run for Porsmilin is a mixed bag, and you’re gonna have to pick your moments. The first few days are pretty average, with a lot of onshore and cross-onshore slop. There’s a real window mid-period that shows some promise, but the standout of the whole stretch is right at the very end, and it’s a big one.
Wednesday, September 9th: We start with a bit of size, 5.6ft of west-northwest swell with a 9-second period. The wind is cross-offshore from the NNW at 12 mph, which is keeping it clean. The combined energy is moderate at 627. It’s surfable, but the models are hinting at iffy tides, so don’t expect perfection. Water temp is 63.7°F, which is pretty much normal for this time of year. Afternoon drops a touch to 4.9ft, but the cross-off from the NW at 9 mph has it looking clean.
Thursday, September 10th: Forget it. The swell drops right off to under 3ft, and we’ve got onshore winds from the SSW and SW blowing 9 to 16 mph. It’s poor. Not worth the paddle.
Friday, September 11th: Small again. 5.2ft in the morning with a light WNW cross-shore, but it’s not organised. By afternoon it’s down to 4.3ft and the cross-shore picks up a bit, making it choppy. It’s poor, plain and simple.
Saturday, September 12th: More onshore junk. Swell is small, 3.3ft, and the wind is cross-on from the southwest, 9-12 mph. It’s a mess. The afternoon does have a longer 13-second period, but it’s still poor.
Sunday, September 13th: A bit more size shows up – 5.9ft in the morning, with the period stretching to 11 seconds. The wind is a light WNW cross-shore, so it’s not terrible, but it’s still lumpy. The energy is building to a moderate 820. Still, questionable tides make it marginal. Afternoon drops to 5.2ft with a cross-on wind. Not great.
Monday, September 14th: This is a tease. The morning is glassy with a light NNE breeze, but the swell is tiny at just 2.3ft. You’ll see a few clean little waves, but it’s very ordinary. A morning paddle for the keen ones, maybe.
Tuesday, September 15th: Small and weak. A brief window in the afternoon with a clean 3.0ft wave on a cross-off NW wind, but it’s not doing much.
Wednesday, September 16th: Size returns, but so does the wind. 4.9ft of swell, but with a strong SSE cross-on at 16 mph in the morning, it’s ugly. The afternoon gets worse with a direct onshore SSW wind and the swell jumps to 4.9ft with a 12-second period. The energy is strong at 960, but it’s going to be blown-out chaos.
Thursday, September 17th: The energy is still there, 5.9ft at 9 seconds in the morning, but it’s got a cross-shore wind and it’s lumpy. The afternoon cleans up a bit with a cross-off from the NW at 12 mph, dropping to 4.6ft. It’s marginal, but you might find a couple of workable ones if you’re desperate.
Friday, September 18th: Small and clean, but weak. The morning has 3.0ft with a moderate offshore N wind, and the afternoon has a long-period 2.0ft wave at 15 seconds with a fresh offshore N breeze. It’s clean but super small. Not worth getting wet for.
Saturday, September 19th: Now we’re talking. This is your first real standout. The morning brings a solid 5.2ft of west-northwest swell, with a 12-second period. The combined energy is strong at 687. The wind is a light,

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.
