The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for Porsmilin over the next couple of weeks.
Right now, we are in a bit of a flat spell. There’s nothing worth paddling out for on the 7th or 8th of September. The 8th is a write-off with a near-gale force wind ripping in from the north at 37 mph. That’s a full-blown blowout, not surf. So we have a gap right at the start.
The first real chance of a surf comes on the morning of Wednesday the 9th. Porsmilin will have a clean-looking 5 ft swell out of the NW with a 9-second period, and a gentle breeze from the NNW keeping it clean. The combined energy is moderate (548). It’s not going to blow you away, but it’s a window to get wet. Water temp here is 64°, which is about normal for this time of year, nothing unusual.
The standout window in this whole run is looking like Wednesday the 16th. The morning session shows a solid 6 ft groundswell from the WNW with an 11-second period. Wind is light and cross-off from the NNW, meaning clean conditions. Combined energy is strong at 777. This is the pick of the forecast – a true clean offshore runner with good shape and power. It could be a bit much for beginners at that size, but for any intermediate and above, this is the one to circle.
Another notable one is Saturday morning the 12th. Don’t let the 2 ft wave height put you off – that’s a very long-period 15-second groundswell from the WNW. It’s glassy, with no wind. Combined energy is only 255 (weak), but those long lines will wrap in nicely and offer some clean, shapey waves if you can get the tide right. This is a peaky, glassy morning for the patient surfer.
After that, the second week gets messy. The 17th through the 22nd sees mixed conditions with onshore winds and choppy seas. A few clean windows pop up here and there, like Monday the 21st morning with a cross-off breeze and 4 ft NW groundswell (410 combined energy), but nothing that holds a candle to the 16th. The last few days of the run taper off into small, weak surf with a lot of cross-on or onshore wind.
Bottom line: the best bet is Wednesday the 16th of September. Clean, solid, and punchy. Get on it.
Rusty.
