The Lowdown
Alright folks, Rusty here. Let's have a look at what Porsmilin has in store for us over the next couple of weeks. We're gonna have to be patient because the first few days are a write-off, but there's light at the end of the tunnel.
Right now, Saturday the 12th through the end of Monday the 14th is a no-go. We've got small, weak swell with lousy wind, so don't even bother suiting up. Tuesday the 15th morning finally gets a little something - a clean 2ft wave from the WNW with a light offshore breeze, but it's tiny and the energy is weak (171). It's surfable, but barely.
Wednesday the 16th sees the swell bump up, but the quality is still struggling. Wednesday afternoon is where it gets interesting. The swell jumps to 7ft from the WNW with a very long period of 12 seconds, creating a massive wave energy spike (1910). The wind is clean offshore, so it'll be lined up, but that size and power is expert territory only. It's a real standout, but only if you've got the skills. By Thursday the 17th, it's dropping back down and the wind turns onshore again, so it's back to marginal.
The next real window of opportunity looks like Friday the 18th. The morning brings a solid 7ft WNW groundswell with a long 13-second period and very light wind. The energy is pumping (1672), but the cross-shore wind means it won't be perfect. Still, it's the best looking day for the confident intermediate, even if it's a touch big for beginners. The afternoon gets a bit choppier.
Sunday the 21st of September is another one to circle. We're looking at a solid 5ft from the WNW with a good 13-14 second period and a fresh offshore wind from the NE and NNE. The energy is still very high (990). This will be clean and powerful, but that offshore wind will hold the wave face open nicely. It's a standout for anyone who can handle a bit of punch.
The very end of the window, Wednesday the 23rd, has a smaller, clean 3ft wave from the WNW with clean conditions, but it's a drop-off in size from earlier in the week. The highlight of the whole run, really, is Wednesday the 16th afternoon for the experts and Friday the 18th morning for the strong intermediates. The daily crowds at Porsmilin can be a factor – it's a spot that can get busy, especially when it's good like that.
The water temp is sitting at 63°, which is bang on average for this time of year, so it's not a shock to the system.
So, in short: first week is grim, then we get a proper pulse of swell mid-month. It's not an easy run, but there are some proper days in there if you pick your moment.
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.
