The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Well, I’ll be honest with you, it’s a pretty grim start. The whole first week is a write-off. From Wednesday the 29th right through to Tuesday the 5th of August, we’re looking at tiny, weak waves and poor conditions. The combined wave energy is barely a whisper, with readings sitting between 15 and 61 – that’s barely enough to get a ripple going. The water’s a touch warmer than normal at 65°, but that’s not going to help you get a wave.
The first real glimmer of hope doesn’t come until Saturday the 8th of August. Now, that’s a long wait, nearly a full week of flatness. For Saturday morning, the clouds break and we get a glassy morning with a 6 ft swell from the west. The energy jumps up to 489 (moderate), which is a proper sign of life. The glassy conditions are a big, big plus. This is the best on offer, but it’s a long way out, so keep your fingers crossed. It’s a good size but not massive, so it’s worth a look for anyone who’s not a total beginner.
Sunday the 9th and Monday the 10th of August see the swell drop back to around 3 ft, with clean conditions in the mornings but nothing to write home about. The energy is light (95 to 117). The pattern is inconsistent, so don’t get your hopes up for a stellar session.
The best swell of the whole period actually shows up on Friday the 7th of August, with a 8 ft to 8 ft west swell and a massive energy reading of 713 to 1164. That’s strong to very strong. But the wind is onshore or cross-onshore, and the forecast says “poor surf conditions.” It’s a shame because that’s a lot of power, but it’ll be a choppy mess. That’s more for the kite surfers than us paddle guys.
So, the standout is Saturday the 8th of August. The glassy morning and that 6 ft west swell at Mawgan Porth is the one to circle on the calendar. It’s a river break, so it’s not often pumping, but when it does, it can be a fun little wave. The crowds can be an issue sometimes, so get there early.
Rusty.
