The Lowdown
Alright, Rusty here. Let’s take a look at what Porsmilin has in store for us over the next couple of weeks. It’s a bit of a slow burner, but there’s some promise on the horizon if you’re patient.
Right now, there’s nothing really going on for the first few days. Monday the 10th is small and messy with a weak 2.3 ft NW swell and a stiff cross-off wind, so leave the boards in the car. Tuesday and Wednesday don’t get much better—tiny waves, poor conditions, and not worth the paddle out, though Tuesday morning has a light offshore breeze. Water temp is sitting around 64.9°, which is about average for this time of year.
Thursday morning on the 13th is the first real glimmer of hope. We’ve got a 3.9 ft W swell with a 11-second period, giving it a bit of push and energy (329 combined energy). The wind is a light cross-off from the NW, keeping things reasonably clean. This is for the intermediate crew, nothing too crazy. Thursday afternoon the wind picks up, though, so morning is definitely the call.
We go quiet again through Friday and Saturday, with small, ordinary waves, though Saturday morning (15th) has a clean 3.6 ft WNW swell with a moderate offshore wind—surfable, but nothing that’ll get the heart pumping.
It’s pretty much a flat spell after that until the following Thursday morning the 20th, which brings a 3.3 ft WNW swell but with onshore wind, so it’s choppy. Not great. Friday the 21st morning shapes up better with a clean 3.0 ft WNW swell, light offshore breeze, and a 10-second period. Decent for a quiet session if you’re keen.
Now, here’s the standout. Mark your calendar for Tuesday the 25th. The morning looks absolutely firing. We’ve got a 7.5 ft WSW swell with a 10-second period, pumping out 978 combined energy. Glassy conditions—zero wind. This is proper, powerful groundswell heading straight into Porsmilin. For the experienced surfers, this is the window. The afternoon drops to 6.9 ft, still solid, but with a cross-off breeze. The morning? That’s the one. Just know that with this much size and long period, the sandbar might handle it better at certain tides, but if the shape is right, you’ll be grinning.
So, to sum it up: Thursday the 13th morning is a decent warm-up, Friday the 21st morning is a nice clean little session, but Tuesday the 25th morning is the absolute standout—big, glassy, and powerful. It’s a long wait, but it could be worth it.
Stay stoked.

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.
