Porsmilin Surf Forecast and Surf Report

Alright, grab a coffee and settle in, because the next couple of weeks around Porsmilin are a proper mixed bag. We’ve got a long stretch of flat, clean days ahead, but there’s a serious pulse of energy building for the end of the month that’ll shake things up.

Right now, from Friday the 17th right through to Saturday the 26th of July, we’re looking at a pretty flat spell. The swell is tiny, mostly 1 to 2 feet from the west or northwest, with weak energy readings mostly in the teens or low twenties. It’s clean, with some glassy moments on the morning of Thursday the 23rd, but there’s simply no power to push anything worthwhile. You’ll be floating around on a longboard at best. This is a good gap to get other stuff done.

Things start to wake up on Sunday the 27th of July. The swell climbs to 4 feet from the WNW (period 9 seconds), but the wind swings onshore and cross-onshore, making it choppy and lumpy. The energy is ramping up though (207 on Sunday morning), and by Monday the 28th of July, the swell is 5 to 6 feet with a longer period of 12 seconds. The energy readings jump dramatically to 457 and then 1184 – that’s proper power. The catch is the wind is still cross-shore, so it’s not clean, but the swell is building.

Now, the standout event is Thursday the 30th of July. This is the big one. Look at the morning: a 15-foot swell from the WNW with a very long 12-second period, and the wind is a gentle cross-offshore breeze from the NW. The combined energy is a massive 5157, which is enormous. This is a serious, heavy groundswell. But – and this is a big but – the forecast is clear that this swell is too big for Porsmilin. This is for experts only, and even then, it’s a beast. The wave state is clean, but you’d need a big-wave gun and a lot of experience. The afternoon is a bit smaller at 13 feet, still huge.

Friday the 31st of July is your best bet if you’re not a big-wave charger. The swell drops to a still-sizable 8 feet in the morning and 7 feet in the afternoon, with a 10-second period from the WNW. The wind is light and offshore, keeping it clean. The energy is still very strong (2514 and 1518). This is described as excellent for experienced surfers. The brutal NW groundswell, with that very long period, will be better on a point or reef, but for Porsmilin’s sandbar setup, it might break a little top-to-bottom. Still, this is the window to get in the water if you’re comfortable.

Saturday the 1st of August drops back down to 5 feet with a short 7-second period and cross-shore wind, so it’s back to messy conditions.

The water temperature has been a steady 65°F, which is a couple of degrees above the long-term average for this time of year – noticeably warm for a wetsuit, but you’ll still want a spring suit.

Overall, the best on offer is that late July/early August swell. The real standout is Friday morning the 31st of July when the size is still solid but manageable, and the conditions are clean. The Thursday the 30th is a monster, but only for the brave.
