The Lowdown
Right then, let’s have a proper look at what the next couple of weeks are serving up for Portreath Harbour Wall.
To be brutally honest, it’s a bit of a grim outlook for the majority of the period. We’ve got a solid run of poor surf conditions stretching from the 8th right through to the 17th. There’s energy out there, but the wind is just going to ruin it, with a lot of cross-onshore and onshore slop.
The first real highlight doesn’t show its face until Friday the 18th. The wind swings around to the east and goes cross-offshore, cleaning things right up. The swell is still small, around 3ft from the WNW, but it’s clean and that’s something. Saturday the 19th is similar with 3ft from the WNW, and then into Sunday the 20th we drop back to 2ft. Nothing epic, but it’s the most surfable run we get.
The standout window, though, is looking like Monday the 21st through to Wednesday the 23rd. The swell bumps back up to a consistent 4ft to 4ft from the west and WNW, with the period stretching out to 11 and then 13 seconds on the Wednesday morning. It’s still only a small-medium wave, but with that clean east cross-off wind, it’ll be the best shape we see. The wave energy is moderate, with values peaking around 476 on the Wednesday morning.
Water temp is sitting at 64°, which is a touch warmer than usual for this time of year, so you won’t need the thickest suit just yet.
Just remember, this is a fairly consistent reef set-up, and with the crowds listed as often, you might have some company out there, even on the smaller days. For the long-range stuff, it’s looking promising, but we’ve got a while to wait, so treat that as a hopeful forecast rather than a certainty.
