Portreath Beach Surf Forecast and Surf Report

Right then, let’s have a look at what’s on the cards for Portreath Beach over the next couple of weeks.

Honestly, it’s a bit of a tough stretch. The forecast is full of messy, lumpy, and wind-affected conditions, with very few windows of clean surf. The water temperature is sitting at 64°F with an anomaly of 2°F, so it’s pretty much what you’d expect for this time of year, neither particularly warm nor cold.

The first proper surfable session doesn’t show up until Wednesday morning, 26th August. It’s small, with a weak 2ft swell from the west at 8 seconds, and the combined energy is a humble 55. The wind is SSE offshore, so it’ll be clean and glassy. But, the swell is tiny and the surf quality is described as poor, so it’s more of a longboard or log session for the dedicated.

From there, things get worse. The wind swings cross-shore and onshore, the swell gets bigger but blown out, and the surf quality remains poor. A few days in early September bring a marginal chance on Monday 31st August afternoon, with a 7ft west swell (period 10 seconds) and a combined energy of 771, but the wind is messy cross-shore. It’s a tough call.

The real standout, if you can wait, is Thursday 10th September. The morning brings a moderate 8ft west swell, with a solid 11-second period, pumping in a combined energy of 1553. The wind is from the northeast, cross-offshore, and the message says “clean.” That’s the best window on offer. The swell direction is a bit off the optimum for Portreath (which likes NW), but it’s still the biggest and cleanest looking swell of the period. The afternoon holds a 10ft west swell, but the wind turns cross-shore, so the morning is the pick.

Before that, there’s a long gap of poor or marginal days. The week of 2nd September through to 9th September is mostly a write-off, with onshore winds and lumpy, messy conditions. The Saturday 5th September morning has a clean 6ft west swell (period 11 seconds) and cross-onshore wind, but it’s marginal at best, with a low score.

So, to sum it up: it’s a slow start, a long middle section of poor surf, but the morning of Thursday 10th September looks like the one to aim for, with a decent-sized, clean, long-period swell. Keep an eye on that forecast, as it’s a week and a half out, but it’s the most promising.
