Porsmilin Surf Forecast and Surf Report

Alright folks, Rusty here. Let's break down what Porsmilin has cooking for us over the next couple of weeks.

Honestly, it’s a tough start. The first real chance of anything surfable doesn’t come until Saturday afternoon, August 8th. Before that, it’s tiny and messy—don’t even bother. We’ve got a long stretch of flatness from now until then.

Thursday, August 6th is a washout. A weak 3ft swell from the NW with a short period and combined energy of just 93—pathetic. Wind is howling 15 mph from the NNW. Stay home.

Friday, August 7th is even worse. The swell drops to 1ft in the morning, though it has a slightly longer period at 9 seconds, but that combined energy is a measly 28. Not worth a second look.

Saturday, August 8th gets a little better in the afternoon. The swell pushes up to 2ft from the NW with a 10-second period, and the combined energy climbs into moderate range at 108. The wind goes light from the NNW at 6 mph, making for clean conditions. It’s surfable, but very ordinary—waist-high waves for the desperate.

Sunday and Monday, August 9th–10th are similar—2ft to 2ft swells—with NW winds keeping it cross-off and clean, but the energy stays weak to low-moderate (75–89). It’s frustratingly small.

Tuesday morning, August 11th, is a tease. The wind drops to glassy—3 mph from the NE—so conditions will be perfect. But you’re still looking at only 2ft of 8-second WNW swell with combined energy of just 55. Clean, but small and weak.

Wednesday, August 12th is the first sign of life. The morning brings 3ft of 10-second W swell with combined energy of 154—solid moderate for the first time. Wind is light from the NNW, clean. It’s surfable, but ordinary. The afternoon gets a bit more size at 4ft (195 energy), but the wind picks up to 15 mph from the NW, making it poor.

Thursday morning, August 13th, is where we finally get something. This is the standout of the whole outlook. Swell builds to 4ft from the W with a 10-second period and combined energy of 340—that’s a solid, moderate energy level. The wind is a light 6 mph from the NNW, keeping it cross-off and clean. Expect good surf conditions. This is the morning to be in the water. The afternoon fades with stronger wind and marginal conditions.

Friday, August 14th, morning has a gentle offshore breeze from the NNE at 9 mph, clean, with 3ft of W swell (9 seconds, 153 energy). It’s surfable but ordinary.

The second week slides downhill fast. From Saturday, August 15th, onward, the swell gets shorter period (7 seconds) and combined energy drops into the weak range (94–111). Winds get messy with onshore components from the WSW and W.

Monday, August 17th, morning offers a brief flicker: 4ft from the W, 9 seconds, 241 energy, with a light offshore from the N. Surfable but ordinary.

After that, it’s a slow fade. The last week from August 18th onward is mostly flat and unrideable, with tiny 0.7ft to 1ft swells, onshore winds, and combined energy barely breaking 50. By August 21st, the wind is howling 18 mph from the WNW, but the swell is gone.

Bottom line: If you’ve got any flexibility, make a plan for Thursday morning, August 13th. That’s your one solid session in an otherwise lean forecast for Porsmilin. Everything else is small, weak, or just not worth suiting up for.

Stay salty,
Rusty
