Porthtowan Surf Forecast and Surf Report

Alright, Rusty here. Let's have a look at what's coming our way for Porthtowan.

We're looking at a pretty quiet start to the outlook. The first few days are a bit of a write-off, honestly. The swell is tiny and the winds are all over the place, mostly cross-off, which isn't doing us any favours. It's a bit of a slow start, but don't lose hope. The water temperature is about average for this time of year, nothing special to report.

Kicking things off Sunday, the 23rd, we've got small, weak waves around 1ft coming from the southwest. The swell period is a really long 14 seconds, which is a proper groundswell, but with almost no energy behind it (81), it's just not enough to get excited about. The wind is a light cross-off, so it's clean, but you're looking at knee-high dribble. It's surfable, but only just.

Monday the 24th and Tuesday the 25th are a total write-off. The wind is pumping, so the ocean is messy. The swell is still tiny, and the energy is dropping. Don't bother paddling out.

Wednesday the 26th shows a tiny flicker of life. The morning has a 2ft swell from the west with a short 8-second period, and the wind is finally offshore, from the SSE. It's clean, but the wave energy is still weak (86). It's surfable, but very ordinary.

Now, Thursday the 27th is where things get a bit more interesting. The swell jumps up to 6ft from the SSW. The energy is moderate (383), but the period is a short 8 seconds, so it'll be a bit crumbly. The wind is a cross-off, so it should be clean. That said, the conditions are described as marginal, so it's not a slam dunk. It's a bit of a gamble, but the size is there.

Friday the 28th has an onshore wind, which is a shame. The swell is a solid 5ft from the SW, but the wind is ruining it. It's a pass.

The weekend of the 29th and 30th is a complete blowout. Big onshore winds, messy, lumpy waves. Not for surfing. You'd be better off with a kite if you're into that sort of thing.

We get a bit of relief on Monday the 31st. The wind goes light offshore and then even glassy in the afternoon. The swell is small, 2ft to 3ft from the west, with a short 8-second period and low energy (123-133). It's clean, but it's small. A fun little session for a longboard or a foamie, but nothing to write home about.

The first few days of September are a bit of a mess with onshore winds and tiny surf. Not worth it.

Now, here's where it gets good. Thursday the 3rd of September looks like the standout. The swell is 5ft, coming from the west, with a moderate 7-second period. The energy is strong (319), and the wind is a light, cross-off breeze from the south. It's clean, and the conditions are expected to be good. This is the one to circle on your calendar. The size is solid for a good paddle, and the light wind should make for some clean, fun waves.

Friday the 4th of September is also worth a look. The morning has a similar 5ft swell from the west, but with a slightly longer 9-second period, giving it a bit more push. The energy is strong (454), and the wind is a light cross-off. It's looking good, but the afternoon gets messy with a fresh breeze.

The last weekend of the outlook is a bit of a wildcard. Saturday the 6th of September has a big 8ft swell from the west, but the wind is mixed. The afternoon, however, has a clean cross-off wind and huge wave energy (1119). That's a lot of power, but the swell period is a short 7 seconds, so it'll be a bit of a washing machine. This one is for the experienced crew only. It's a couple of weeks away, so keep an eye on it, but it could be a proper session.

So, for the best bet, I'd say Thursday the 3rd of September is your best shot. Get up early, and you'll be rewarded with clean, chest to head-high waves with a light offshore breeze. The Friday the 4th of September morning is a close second, but the window is smaller. The big swell on the 6th of September is for the pros only.

Keep your eyes on the forecasts, things can change. Rusty out.
