The Lowdown
Alright folks, Rusty here. Let’s get into it for the next couple of weeks around Porsmilin. It’s a bit of a slow burn, but there’s a window of real quality if you’ve got the patience.
First thing to note, the water temp is sitting at 64°, pretty much bang on average for this time of year, so no surprises there.
The first week is a tough one to love. The swell is small and weak, mostly around 2ft to 2ft with a short period, and the wind is often cross or onshore. Saturday the 8th and Sunday the 9th are a write-off – that morning cross-shore and light cross-onshore won’t give you anything worth paddling for. Monday the 10th morning has a tiny 2ft NW swell with a 9-second period, but the NNE offshore wind is light, so it’s clean. The energy is weak (100), and it’s just ordinary surf. Tuesday through Thursday stay small and messy, with the energy rarely breaking triple digits. By Thursday the 13th morning, the swell bumps up to 4ft from the west with a longer 11-second period, giving us a bit more push (284 combined energy), and the wind is cross-off from the NNW, so it’s clean. It’s still only marginal, but it’s the best of a pretty average week.
The real gem is hiding in the second week. Wednesday the 19th morning is the standout. The swell comes up to a solid 8ft from the NW, with a 9-second period, and the wind is offshore from the NNE at just 6 mph. The combined energy is a very strong 935, and the conditions are forecast to be very good. This is a powerful, clean wave for experienced surfers – that size is expert territory, so don’t take it lightly. The NW swell direction is a perfect match for Porsmilin’s optimum. If you can get out there, that’s the morning to circle.
The run-up to that is a bit lumpy. The afternoon of the 17th and the 18th see some bigger swell (up to 7ft) but with strong cross-winds making it choppy and unappealing for a paddle. Kite surfers might have a look at it, but for a surfboard, it’s not the one.
After the 19th, things settle back down. The 22nd and 23rd mornings have a consistent 5ft to 5ft NW swell with clean offshore winds (NNE), but it gets a bit breezy in the afternoons, and the comments suggest it’s only marginal. Still, it’s a far cry from the flat spell at the start of the forecast.
To wrap it up: the first week is a slog, with only a few glimmers. The second week, specifically the morning of the 19th, is your real shot at something special. Get on it if you can. Until next time, this is Rusty signing off.

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.
