The Lowdown

Alright, grab your wettie, let’s talk about what’s on the menu for Porsmilin over the next couple of weeks.

Straight up, it’s a bit of a rough start. We’ve got some serious size and wind through the first few days that’s going to make things pretty ordinary. There’s a big swell running on Saturday the 29th of August, around 10ft to 12ft, but it’s coming with a gale-force cross-onshore. That's not a paddle, that’s a washing machine. The combined energy is huge (1044 and then a massive 2662), but the wind state ruins it completely. If you’re looking to get wet that weekend, you might be better off with a kite. Sunday is just as messy with onshore winds and a risk of storms.

Monday the 31st has some cleaner moments. The swell is still a solid 8ft from the west with a 10-second period, and in the afternoon we get a clean cross-offshore wind. The combined energy is strong at 1380, and that clean wind means the lines should be good. It’s still a bit meaty for beginners at that size, but for an intermediate surfer, Monday arvo is your first real window. The crowds could be an issue here though, so get out early if you can. Water temp is about average for late August.

Tuesday the 1st of September drops off to a smaller 4ft, but the wind is a light cross-shore, so it’s not terrible. We scrape through for a marginal session.

The real standout, the one to circle on the calendar, is Saturday the 5th of September. We’ve got a clean 6ft swell out of the west-northwest with a solid 11-second period. The wind? Dead calm. Glassy. Perfection. The combined energy is a moderate 718, and everything lines up for good, clean waves. This is as good as it gets at Porsmilin. The swell direction is matching the optimum southwest direction nicely. It’s not huge, so it’s good for intermediates too. A proper morning session.

After that, we get a bit of a lull through Sunday the 6th and into the week, with small onshore swell. Then Monday the 7th and Tuesday the 8th of September look interesting again. Tuesday arvo sees a massive 12ft swell out of the west-northwest, with a long 11-second period, and combined energy through the roof at 2820. The wind is a moderate cross-shore. However, the file notes the surf is predicted to be too big for this break. That’s a big, powerful wave only for experts who know the bank. Long-period swells can get a bit straight at a sandbar, but on a west-northwest swell, this spot should handle it.

The rest of the week after that fades out with messy conditions and onshore winds, finishing with a couple of small, blown-out days leading into the second weekend.

So, bottom line: Saturday the 5th is the golden ticket for a clean, glassy session. Monday the 31st arvo is a solid backup if you can handle the size. The big Tuesday on the 8th is a serious option for experienced crew only.

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.
