The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks for Portreath Harbour Wall.

First thing you need to know: the water temp is sitting about average for this time of year. Nothing unusual there. The bad news is that the first few days are a real struggle. We’ve got a tiny bit of weak swell to start Monday, but with a stiff 22 mph cross-off wind, it’s a write-off. Tuesday brings a little more size, but the conditions are still ordinary. The best we can say is Tuesday afternoon sees a modest 2 ft swell from the WNW with a light offshore, but the combined energy is only moderate (115) and the quality is “very ordinary.” Not one to get excited about.

Wednesday the 26th is a write-off again with tiny waves and poor winds. The pattern holds through the end of the month. We get a bump in size on the 27th with 5 ft to 8 ft from the SW (period 11 seconds), but the wind is all over the place – cross-shore and messy. The energy jumps up to strong levels (1184), but it’s just not clean. Thursday and Friday are similar. There’s a long stretch of days where the wind just won’t play ball, and the surf is either too small or too chopped up. It’s a frustrating run.

The standouts? Honestly, there’s only one real window that looks like it could be special. Mark your calendars for Sunday the 6th of September. The swell really turns on with a 6 ft to 7 ft groundswell from the west, and the period is *very* long – 17 to 19 seconds. That’s a serious amount of energy pouring in, with values over 2500. The wind is light and *on*, which for a reef setup like this is a major positive. This is a classic reef-break swell, and it’s going to be clean. The 6 ft to 7 ft is a solid size, but with that long period, it’ll be powerful and a bit more challenging. It’s really only for the experienced crew. The Monday after (7th September) still has some nice 6 ft swell with a long 14-second period, but the wind turns a bit cross-on, so it won’t be as pristine. The 6th is the day to keep an eye on. It’s a long way out, so treat it as promising but not locked in.

The rest of the forecast is a washout. It’s a tough outlook for the next week and a half, with a lot of poor surf and strong winds. The setup is often more interesting for kite surfing than paddle surfing during those days. But that one window on the 6th looks like a true standout for those who can handle the power.

Stay patient, and keep an eye on that long-range window.
