The Lowdown
Alright, Rusty here. Let’s have a look at what’s going on for us.
Right then, it’s a bit of a rough start here at Porsmilin, a sandbar setup that’s fairly exposed and picks up swell from the southwest. The water’s sitting at 65°, which is bang on normal for this time of year, so nothing to worry about on that front.
The first few days are a write-off, to be honest. From Thursday the 27th right through the weekend, we’ve got onshore and cross-onshore winds messing things up. The swell is there, reaching 8ft by Saturday afternoon, but the wind is strong and messy, making it poor for paddling. The energy is moderate at first, hitting 125, but builds to 956 by Saturday, which is almost strong. Doesn’t matter though, it’s just blown out. You’d be better off looking at kitesurfing with that wind. Sunday the 30th and Monday the 31st stay poor, with energy climbing over 1000 on Monday morning, but the wind is still onshore or cross-onshore, so it’s a no-go.
We get a bit of a break on Tuesday the 1st of September, but it’s still cross-onshore and small, only 4ft. Then Wednesday the 2nd is glassy in the morning, which is lovely, but the swell is tiny at 2ft and the energy is weak at 88. Not worth suiting up.
Thursday the 3rd kicks up a bit to 6ft, but the wind is onshore again, so it’s messy. The real standout doesn’t appear until Friday the 4th of September. That morning is the pick of the whole forecast. We’ve got a clean 6ft swell from the west-northwest, light offshore winds from the northwest, and the energy is strong at 780. The swell period is a solid 10 seconds, so it’s got some shape. This is your best window for a good session. The afternoon stays clean with a cross-shore wind, but the period stretches to 12 seconds, which is a long period groundswell. That can make Porsmilin, being a sandbar, a bit tricky as it might break too straight, but it’s still good energy.
After that, Saturday the 5th gets messy again with onshore winds, and the swell hangs around 7ft to 7ft, but the wind kills it. Then Sunday the 6th has a glassy morning with 4ft from the west, which is worth a look if you’re desperate, but it’s small.
The real promising stuff comes in the second week. On Monday the 8th of September, we get a proper offshore wind from the north-northeast, with a clean 6ft swell from the west-northwest, energy at 440. That’s a solid session. Tuesday the 9th has a clean 7ft from the west in the morning, but the period is short at 7 seconds, so it’ll be a bit weak. Wednesday the 10th has offshore winds again, 5ft from the west with a good 10-second period, clean.
Then, the big one looks like Friday the 11th of September. That morning has a 8ft swell from the west, offshore winds from the north-northeast, and energy at 823. That’s a strong, clean swell, but at 8ft, it’s getting into expert territory. The period is 9 seconds, so it’s solid. The afternoon keeps it clean with 7ft and energy at 1346, which is very strong. That’s a proper session for the experienced crew.
So, to sum it up: the first week is a write-off. Friday the 4th of September morning is the first real standout. Then the second week, especially Friday the 11th of September morning, looks like the best of the bunch, but it’s a long-range call, so keep an eye on it.

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.
