The Lowdown
Alright, let’s take a look at what’s coming our way for Portreath Beach.
Honestly, the next week and a half looks pretty grim for any decent surf. We’ve got a long stretch of poor conditions starting from now, right through until the 10th of September. The swell’s not bad at times – you’ll see a few pulses around 7 to 8 feet – but the wind is just a mess. Mostly onshore or cross-onshore from the west and northwest, strong and gusty, making everything choppy and blown out. The energy is there, with readings up to 1632 on Monday the 7th, but it’s wasted. For a beach break like this, that’s no fun for a surfer.
The water is sitting at about 64°, which is a touch warmer than usual for this time of year. Nice for the skin, but won’t fix the surf.
We finally get a little window of hope on Friday the 11th. The morning brings a clean, cross-offshore breeze from the SSW, with a 5 ft swell from the WSW, period of 9 seconds. It’s not huge, but the energy is low at 287, so it’s a small, clean, friendly wave. Not a standout, but a definite improvement after days of junk. The afternoon gets even better with a light offshore from the SE and a 3 ft swell, glassy and clean. It’s small, but you could get a few fun ones.
Then it’s back to the messy stuff until the real standout arrives. Sunday the 20th of September is the one to circle. The morning brings a fresh offshore wind from the ESE, pushing into a 7 ft swell from the west with an 11-second period. The energy is strong at 1056. That’s a proper groundswell with plenty of push. By Sunday afternoon, it gets even better – still 7 ft, same direction and period, but with a moderate offshore wind and an energy reading of 1103. The conditions look set for some really good, clean waves. That’s the best session of the whole forecast by a long shot. Monday the 21st is still clean and offshore, but the swell drops to 4 ft.
So, the bottom line: don’t hold your breath for the next week and a half. The one true standout is the afternoon of Sunday the 20th at Portreath Beach. That’s the one to plan for.
