Porsmilin Surf Forecast and Surf Report

Alright, Rusty here. Let’s get into it.

Alright, we’ve got a mixed bag coming our way for Porsmilin. To be honest, the next day or two look a bit average, but there’s some serious potential later on if you’re patient.

We start off Tuesday afternoon with a clean but a bit bumpy 6 ft cross-off swell from the WNW. The energy is moderate (574), but the conditions are just marginal. Wednesday builds nicely with a 8 ft to 8 ft swell, still clean, and the energy jumps into the strong zone (1122 on the morning, 1406 on the afternoon). That’s solid, but the scores tell me it’s not quite perfect yet. Thursday gets messy with onshore winds, so maybe give that a miss.

The first real standout is Friday morning, September 18th. We’ve got a 8 ft groundswell from the WNW with a very long period of 14 seconds. The combined energy is pumping at 2742. That’s some serious grunt. The water temp is 63°, which is about normal for this time of year. The issue is the wind is a cross-on, making it choppy. If you’re a skilled surfer and can handle a bit of texture, this could be the one, but for most, it’s going to be a washing machine.

After a couple of poor days, things clean up nicely from Sunday afternoon, September 20th onwards. A light 5 ft swell with clean cross-off winds makes for a nice, fun session. Monday looks great too, with 5 ft swell and a 12-second period, and clean, offshore winds. The energy is moderate but the quality is right.

Now for the real highlight. Tuesday afternoon, September 22nd, a new pulse arrives: 5 ft swell from the west, but the period is a massive 16 seconds. That is pure, long-distance groundswell. The combined energy is very strong at 1650. It’s clean and gentle on the wind. This will be a quality wave.

The next big one to circle on your calendar is Saturday, September 26th. The morning has a 8 ft WNW swell with a 15-second period – energy at 2620. That’s a lot of water moving. But the standout is the Saturday afternoon: 8 ft swell, 14-second period, and light, clean cross-off winds. The energy is still huge at 2092, and the forecast calls it excellent for experienced surfers. If you’re not an expert, maybe skip this one – over 8 ft is expert territory.

Sunday, September 27th afternoon offers a final, more manageable option: 8 ft swell but with a shorter 8-second period and clean cross-off winds. It’ll be punchy but fun.

After that, late September gets too big for comfort at Porsmilin, with swells hitting 12 ft and even 13 ft, and the wind goes unfavourable. The energy readings are extreme (over 4900). That is strictly big-wave territory, and likely more for the experienced crew or kite surfers given the cross-on chop.

So, the best windows are Friday morning September 18th if you don’t mind chop, the clean days from Sunday the 20th through Tuesday the 22nd, and the absolute standout is Saturday afternoon September 26th for experienced surfers.
