The Lowdown
Alright, mates, Rusty here, looking at the next couple of weeks at Porsmilin.
The first few days are a total dud. Friday the 7th through to the middle of the following week, the swell is barely a ripple, with combined energy in the 30s and 60s. It’s knee-high mush, and the water temp is about 64°, which is standard for the season. Nothing to write home about.
Things start to twitch on the morning of Thursday the 13th. A bit of a 3ft swell from the west, with energy hitting 215, but the wind is still cross-offshore. Not amazing, but a sign of life.
The first real session comes on the morning of Friday the 14th. We’ve got a clean 4ft swell from the west-northwest, 322 combined energy, and a nice offshore breeze from the NNE. That’s worth a paddle.
But the standout is the morning of Tuesday the 18th. A glassy 6ft swell from the west, with a massive 435 combined energy. The wind is almost nothing out of the east, leaving it mirror-smooth. That’s a proper session. It’s a bit over 5ft, so it’s heading into intermediate territory, but for the crew that’s ready, it’s a belter. The period is a short 8 seconds, so it’s a wind swell, but with no wind, it’ll be clean.
The morning of Wednesday the 19th is also a cracker, with 6ft from the west-northwest and a clean offshore breeze from the NNE. 424 energy. Good stuff.
Then, on Saturday the 22nd, the swell jumps to 7ft from the west-southwest, with a huge 1076 combined energy. That’s powerful. But the wind is messy cross-shore, and the period is short, so it’s going to be a messy, choppy beast. At that size, it’s experts only, and with the cross-shore, it’s looking more like a kite day.
So, bottom line: the first week is a flat spell. The best bet is the morning of Tuesday the 18th and Wednesday the 19th. The big swell at the end is a brute, but the wind is going to ruin it for now.
Rusty.

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).
