The Lowdown
Right then, let’s have a look at what’s on the cards for Porsmilin over the next couple of weeks. The forecast opens with a bit of a flat, grotty spell, but don't let that get you down – there are some proper windows of clean surf coming, especially later on.
Alright, first up, Sunday morning on the 6th of September is a non-starter. We've got a small 4ft swell from the WNW, but it's coming with a cross-onshore breeze that's just messing it up. The water's sitting at 63°F – bang on average for the time of year, so that's fine, but the surf is poor. The afternoon is much the same, with a weak 3ft wave. Just a write-off, really.
Monday the 7th is where things start to get a bit more interesting. The morning sees a jump in size to 7ft from the west, and the combined energy is strong (1367). It's still a bit cross-onshore though, so it's only marginal. The real highlight of the early week is Monday afternoon. The swell drops just a touch to 6ft from the west, but the wind swings to a light cross-offshore from the NW, cleaning it right up. The energy is still pumping (1164), and the period is a nice, long 13 seconds. This is the first standout of the forecast. For an intermediate surfer, this is your session.
Tuesday the 8th is a bit of a mixed bag. The morning drops to 5ft with a 10-second period, and while it's clean with a light cross-off wind, the quality is just "good". The afternoon gets a bit windier, and the score drops. Wednesday the 9th sees the swell pick up again to 7ft in the morning, but with a moderate breeze and a cross-shore chop in the afternoon, it's a bit messy.
The next few days, from Thursday the 10th through to Tuesday the 15th, are a write-off for any decent surf. The swell is small, the wind is onshore or cross-onshore, and the conditions are just poor. It's a long, frustrating gap of about six days where you wouldn't bother paddling out. The water temp will stay about normal.
Then we get to the real prize of the long-range forecast. Thursday the 17th of September shows some promise with a clean 6ft swell and a long 12-second period, but the wind is a fresh 19 mph, which is a bit strong for comfort.
But look at Friday the 18th of September. This is the big one. The morning kicks off with a solid 7ft groundswell from the WNW, with a very long 11-second period and a combined energy of 1066, which is strong. The wind is light and cross-offshore from the NW. The forecast says "expect very good surf conditions." This is your best bet of the whole outlook, but it's a week and a half away, so keep an eye on the charts.
The weekend of the 19th and 20th of September also looks promising. Saturday the 19th has a clean 6ft swell with a moderate offshore breeze from the NNE. Sunday the 20th has another standout in the afternoon: 6ft from the WNW with a 12-second period and a light cross-offshore breeze, giving it a combined energy of 1009. That's another very good session.
The tail end of the forecast on Monday the 21st is clean but smaller, with a 5ft swell in the morning and a light 4ft in the afternoon.
So, to boil it down: the first half of the week is a wash, but Monday afternoon the 7th and Friday the 18th of September are the true standouts. Sunday the 20th afternoon is also a beauty. The water temp will stay around 63°F the whole time, which is average. Get your skates on for those sessions.

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.

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.
