The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, I’m looking at this forecast and it’s a tough one. We’ve got a real flat spell on the horizon. For the first ten days or so, from the 27th of July right through to the 5th of August, the swell is barely a whisper. We’re seeing tiny waves, mostly from the south, with a combined energy that’s barely registering – often just single or low double-digit figures (2 to 93). The water temp is about what you’d expect for this time of year, nothing out of the ordinary. It’s a frustrating period for a surfer, with days of near nothing and a lot of clean but empty looking water. The best of a bad bunch might be the 4th of August, when we see a small 4ft easterly swell creeping in, but the period is short at just 5 to 6 seconds, so it’ll be pretty weak and crumbly. The wind is mostly offshore or cross-offshore, keeping the surface clean, but there’s just no power behind it.
Then, around the 5th of August, there’s a small uptick with a 3ft easterly swell and a slightly better period of 8 seconds, giving a combined energy of 93. It’s still not going to be anything to write home about, but it’s the most we’ve seen. The wind holds clean, so it might be worth a paddle for a few small, crumbly waves if you’re desperate.
After that, it drops off a cliff again. From the 6th of August onwards, we’re back to nothing. Flat, clean, and empty. There’s a tiny pulse of 2ft from the SSW on the 9th of August, but it’s weak. The rest of the outlook is a total write-off for surf.
So, the standout? It’s a quiet one, but the best chance will be on the morning of the 4th of August. Kennack Sands might just have a few small, clean waves. It’s a sheltered spot, and with the wind coming from the WSW, it’ll be cross-offshore and clean. The swell is a tiny 4ft from the east, but the period is a short 5 seconds, so it’ll be weak and won’t have much push. This spot is rated as inconsistent, so it’s a gamble. The crowds are *sometimes* around, so you might get a few other desperate souls out there. Honestly, for most of the 16 days, the beach will look better for a kite than a surfboard.
