The Lowdown
Alright, let’s break it down, same story but in feet and miles.
It’s a pretty grim outlook, frankly. We're looking at a long stretch of flat or poor conditions before you even get a glimmer. The first chance you get to even think about paddling out is on Wednesday, August 5th.
So, Porsmilin shows a pulse Wednesday afternoon. We’ve got a 5ft swell from the WNW, with a short period of 7 seconds. The energy is moderate at 471. The wind is a cross-offshore from the NW at 12 mph, which will keep the surface tidy, but the swell direction isn't great for the spot. It only rates a 1 out of 10, meaning it'll be a messy, tricky bank. This is one for the die-hards only.
Thursday morning, August 6th, cleans up a bit more. Swell drops to 4ft from the NW, still a short period, and the energy falls right back to 127. The wind goes lighter, NNW cross-off at 6 mph. It’ll be glassy and clean, but there’s just not enough power to make the sandbar do its thing. You can surf, but it’s going to be a long wait between set waves.
The weekend is dead, with tiny, weak waves. The whole second week is the same sad story. The only other blip on the radar is Monday, August 17th, when a new NW swell rolls in at 3ft with a 10-second period (energy of 148). The wind is a cross-shore from the W at 9 mph, so it's not clean. Then Tuesday the 18th, the wind finally goes offshore from the NE at 15 mph, but the swell has already dropped to 2ft. Typical.
For the full 16 days, the surf is poor. The conditions and the swell energy just never come together. On a sandbar like Porsmilin, a dry spell like this isn't unusual; it’s just the nature of the spot. The forecasts could always change, but as it stands, you’re better off finding another hobby for a couple of weeks.

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.
