The Lowdown
Alright, Rusty here again. Let’s talk about Porsmilin in feet and miles per hour.
The water’s around 65°, which is pretty normal for this time of year, so no wetsuit surprises.
We’re looking at a pretty slow start. For the next several days, wave heights are tiny – mostly 1 to 2 feet, coming from the NW with periods around 8-9 seconds. The combined energy is weak, under 100 (like 96 or 93) – that’s barely a ripple. Winds are cross-off or offshore, so the water will look clean, but there’s just no push to ride. Sunday the 9th is a washout. Monday the 11th has a little 1-foot wave with offshore wind, but it’s not worth paddling out for. This quiet spell stretches out for over a week.
We get a small bump on Wednesday the 18th morning – a 4-foot swell from the NW, but with a very short 6-second period. The combined energy hits 117 (moderate), but that short period means it’ll be weak and bumpy. Not good.
Now, the one day to save the run – Thursday the 20th morning. We finally get a 4-foot swell from the WNW with a 10-second period, and the combined energy jumps to 322 (strong). That’s the real deal. On top of that, we have offshore wind from the NE at 19 mph. That’s going to clean the face up perfectly. This is the best chance for proper surf. The swell direction is close enough to the spot’s preferred SW to work the sandbar. It’s a fairly consistent break, so expect some decent sets. After that, it drops off again, and by the 22nd we’re back to small, weak surf.
If you want a wave, set your sights on Thursday the 20th morning. Everything else is pretty much a flat, glassy wait.
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.
