The Lowdown
G’day, Rusty here.
Alright, let’s have a proper look at Porsmilin. It’s a sandbar setup that’s fairly consistent, but honestly, the next two weeks look pretty ordinary for paddle surfing. We get a few windows with reasonable swell, but the wind and overall quality just don’t line up. Most of the time, we’re looking at poor surf conditions, with onshore or cross-onshore wind messing things up. The water temp is around 64°, which is about average for this time of year.
For the first week, the swell stays small and weak. On Tuesday, August 25th, we’ve got a tiny 2ft WNW swell with a period of 11 seconds, but it’s onshore from the SSW and the combined swell energy is only 111 (moderate). It’s just poor. Wednesday the 26th is a bit of a tease – Wednesday afternoon goes glassy with calm wind, but the swell is only 2ft from the west with a short 8-second period and energy at 75 (weak). It’s clean but tiny and weak – not really worth paddling out for.
Thursday the 27th morning starts to pick up a touch with 5ft from the SW, but the period is a short 7 seconds, and it’s onshore again. Energy climbs to 254 (moderate), but the quality is still poor. Friday the 28th gets a bit bigger – 5ft in the morning and 8ft in the afternoon, but it’s blowing 22 mph onshore and cross-onshore. The afternoon is a messy 8ft with fresh cross-onshore wind and lumpy conditions – that’s more for the kite crew than us. Energy jumps to 912 (strong), but it’s ugly.
The weekend stays similar. Saturday the 29th has 6ft to 6ft with onshore and cross-onshore wind, choppy and poor. Sunday the 30th has 5ft to 4ft, but cross-onshore wind and lumpy again. Monday the 31st goes 7ft to 7ft with cross and cross-onshore wind, fresh and lumpy – still no good.
The first standout is Tuesday, September 1st afternoon. The swell is 8ft from the west with a 9-second period, and the combined energy is 1490 (strong). The wind is cross-onshore at 16 mph, so it’s still choppy, but that’s the biggest, most energetic push of the first week. It’s not perfect, but it’s the best on offer early on.
Then we hit a real promising window. Wednesday, September 2nd morning: 8ft from the west, 10-second period, and only a light cross-onshore breeze at 6 mph – just small wind ripples. Energy is 1147 (strong). The score is marginal due to tide or conditions, but this is the cleanest setup of the first half. It’s worth checking.
After that, the surf drops off. Thursday the 3rd and Friday the 4th are smaller and weaker, with onshore and cross-shore winds. Saturday, September 5th brings another pulse – 8ft in the morning and 8ft in the afternoon from the west, but it’s cross-onshore with 16 to 19 mph winds and energy at 862 to 1057 (strong to very strong). It’s lumpy and messy again.
The real standout is Monday, September 7th afternoon. Swell is 7ft from the WNW with a 10-second period, and the wind turns offshore from the NNE at 19 mph – fresh offshore and clean. Energy is 838 (strong). This is the cleanest, most surfable day in the whole outlook. The wave state is clean, and the wind is off the land – absolute quality for Porsmilin. It’s a bit big for beginners, but for intermediates and up, this is the one.
Tuesday the 8th and Wednesday the 9th go big again. Wednesday, September 9th afternoon sees a 10ft west swell with an 11-second period, energy at 2302 (very strong). It’s cross-shore with a cross-chop, so for experts only at that size. The wave shape will be powerful, but messy.
Overall, if you’re patient, September 7th afternoon is the pick – fresh offshore, clean lines, and a solid 7ft groundswell from the WNW. September 2nd morning is a close second for a cleaner, smaller session. The rest is mostly blown out or too weak. No kite surfing until the bigger days.
Stay tuned, forecasts can change.

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.
