Portreath Beach Surf Forecast and Surf Report

Alright, let’s get real about Portreath Beach. I’m looking at the next 16 days and honestly, it’s a tough watch. The first real chance to get wet doesn’t come until Saturday the 5th of September.

That Saturday morning you’ve got a clean 5ft WNW swell rolling in with a light offshore breeze from the WNW at 6 mph. It’s got a solid 12-second period, so some proper groundswell energy, with the combined energy sitting at 730 — moderate power. The water temp is 64°, about 2° above average for this time of year, so it’s a little warmer than you’d expect. Just a touch. That morning window is your best shot, but the overall call is marginal and crowds are often here, so expect it to be busy.

By Saturday afternoon the wind swings cross-shore and the swell drops to 4ft. Not worth staying in the water.

Sunday the 6th has offshore wind in the morning but the swell is tiny — only 3ft with combined energy of 106. That’s barely surfable.

Monday the 7th sees a big jump in size — up to 8ft WNW with a very long 13-second period and combined energy of 1783 — but the wind is cross-onshore and choppy. That’s going to be blown-out and messy. Too big for beginners, too rough for anyone wanting a clean wave.

From Tuesday the 8th all the way through to the 19th of September, it’s a rough run. Most days have moderate to fresh cross-onshore winds, lumpy conditions, and swell sizes rarely over 3ft, with combined energy often under 200. The period is mostly short, under 10 seconds, so you’re not getting any real drive.

The one glimmer is Sunday the 20th of September. It’s still small — only 2ft from WNW — but the wind is light cross-offshore from the ENE at 6 mph, keeping the surface clean. The combined energy is weak at 77, period is 9 seconds, so it’s not going to be firing. But if you’ve got a longboard or a foamie and just want a clean little glide, that’s your window. Just remember, this is way out at the end of the forecast — promising, but far from certain.

All in all, it’s a lean run. Nearly two weeks of poor to flat conditions with just a couple of very short, marginal windows. This area can go through dry spells like this, and this is one of them. Keep checking back, but don’t hold your breath.
