The Lowdown
Alright, let’s break it down.
Looking at the next couple of weeks, Porsmilin is pretty much a dud. This sandbar break needs a solid SW swell to fire, and we’re just not getting it. The water’s at 65° – about average for this time of year, nothing special.
The first hint of anything rideable comes in on Wednesday afternoon, August 5th. We’ve got a 5ft swell from the WNW, a short 7-second period, and a cross-off wind from the NW at 12 mph. The combined energy is moderate (454), but with that short period, the waves will be weak and crumbly. Marginal at best.
Thursday morning, August 6th, it drops to 4ft from the NW, period just 6 seconds, energy weak (118). Still a cross-off wind, but it’s tiny and gutless. Not worth paddling out.
From Friday, August 7th through the rest of the first week, it’s a total blank. Tiny, weak waves, mostly poor conditions. The swell hardly gets above 3ft, and the energy is pathetic.
Saturday afternoon, August 8th, there’s a small blip: 3ft from the NW, period 11 seconds, energy 146 (moderate), with a clean offshore wind from the north at 12 mph. The waves might have a bit of shape, but it’s tiny. Better for a longboard if you’re keen.
The next small window is Friday morning, August 14th – 4ft from the W, period 9 seconds, energy 281 (moderate), with a cross-off NW breeze at 9 mph. Clean, but still small and average period. Nothing special.
Saturday, August 15th morning is similar: 4ft from the W, period 9 seconds, energy 247, cross-off wind. Still just ordinary.
Tuesday, August 18th gives us a glassy morning with 3ft from the WNW, period 8 seconds, energy 81 (weak). In the afternoon it bumps to 3ft, period 9 seconds, energy 114 – still glassy, but very small. That’s about as good as it gets, and it’s not good.
Honestly, there’s nothing in this 16-day window worth getting excited about. The best bet is the small glassy window on Tuesday, August 18th if you’re a beginner or just want a float. But for proper waves, this stretch is a total bust. The break is fairly consistent, so it won’t stay like this forever, but for now, I’d hang up the board.

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.
