The Lowdown

Right. Let’s take a look at what’s on the table for Porsmilin. It’s a bit of a flat spell to kick things off, I’m not gonna lie to ya. From today, Wednesday the 29th of July, right through until the evening of Monday the 10th of August, it’s pretty much a story of dribble. Over a week and a half of barely a ripple. The energy is weak, numbers barely cracking triple digits most days, and when they do it’s all messy or bumpy. You’d be better off waxing your board for nothing.

Come Tuesday the 11th of August morning, we finally see something barely surfable—a touch of life in the water. But it’s still ordinary, just 3 ft from the west with a short period. Not worth rushing for.

Now, the standout window lights up on Wednesday the 12th of August morning. That’s the one. Porsmilin’s sandbar picks up a solid 7 ft swell from the WSW, with moderate wave energy (520). The wind is light and offshore from the NE, so expect clean lines. It’s a bit much for beginners, but for intermediates this is where it’s at. The afternoon bumps up to 7 ft but the wind swings cross-off and picks up, so the morning session is your golden ticket.

If you’ve got the experience, Thursday the 13th of August morning is the big one. A proper groundswell hits—10 ft from the west with a very long 13-second period, pumping out massive energy (4309). That’s serious power, for experts only. Wind is clean, gentle offshore from the north. This is a standout, but it’s for the crew who know what they’re doing. The long period will mean long gaps between sets and some straight lines on a beach break, but with that size and direction hitting the sandbar right, it should offer up some memorable ones.

The water temperature is sitting about average for the time of year, nothing unusual to report.

So, for the whole run: one proper highlight on Wednesday morning the 12th for intermediates, and a big, expert-only day on Thursday the 13th. The rest is a waiting game.

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.
