The Lowdown

Alright, Rusty here. Let's have a look at what's in store for Porsmilin over the next couple of weeks.

To be straight with you, the next week and a half is looking pretty grim. There's swell on the way, sure, but the wind is just going to mess it up, session after session. We’re looking at a long stretch of poor surf conditions from now, right through until the 4th of September. There's some decent size coming, but it's all cross-on or onshore, so don't expect anything clean. The water temp is sitting at 65°F for the first mention, which is about average for the time of year.

The first real standout doesn't come until Saturday the 5th of September. That morning, the wind finally plays ball. We’ve got a light breeze from the NE, giving us clean, cross-off conditions. The swell is a modest 5ft from the WNW with a period of 10 seconds – that's a nice groundswell, and combined energy is a solid 365 (moderate). It's not going to be huge, but it'll be clean and shapely on the sandbar. Expect the water to be cool, but with the offshore wind, it's going to feel like a proper reward after the wait. Crowds are possible at Porsmilin, so get in early.

The following morning, Sunday the 6th of September, also has potential. We get glassy conditions early, with the wind swinging around to the SE at just 3 mph. The swell drops a touch to 3ft from the W, but that 10-second period is still there, keeping the energy (225, moderate). It's a great window for a long, clean session, but the swell is small so you'll need your log.

Beyond that, it fades out again. There's a brief moment on Wednesday the 9th of September with a glassy afternoon, but the swell is only 3ft from the W, so it's just a fun-sized cleanup set. Not really a standout.

So, to sum it up: the first week is a write-off thanks to the wind. Your best bet is Saturday the 5th of September morning, with a solid, clean groundswell. Sunday the 6th is a close second for a glassy, smaller wave session. Don't hold your breath for much else.

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.
