The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough one. We’re looking at a long, dry stretch with barely a ripple. The whole 16-day window is a bit of a write-off for any decent surf. From now, through to the end of the month, the swell is tiny and the wind is mostly messy. There’s a gap of about 5 days with no recommendation at all, and even when things try to pick up, it’s just not enough to get excited about.
The only real whisper of something rideable comes at Whitsand Bay and Tregantle on Thursday, August 13th. We’ve got a glassy morning with the wind dead calm – that’s a major positive for clean conditions. The swell is a tiny 2 ft from the WSW, with a period of 9 seconds. The combined energy is a weak 67, so it’s really small and lacking punch. The afternoon holds similar 2 ft WSW swell with glassy conditions, but again, the energy is still low at 60. It’s surfable, but very ordinary. The water temperature is about average for the time of year, so nothing unusual there.
For the rest of the period, there’s nothing that even gets close to a proper wave. The wind is either too strong, cross, or onshore, and the swell is just a non-event. By the 17th and 18th of August, we see a bump in swell height to 3 ft and 4 ft, and the energy gets into the three-digit range (101 and 128), but the wind is howling cross-shore or cross-onshore, making it a lumpy, choppy, and frankly poor setup. With that kind of wind and a beach break, this is looking more interesting for kite surfing than a proper paddle session.
So, what’s the call? If you’re desperate, Thursday the 13th is your only real shot at a clean, glassy wave, but don’t expect much. Otherwise, it’s a waiting game. The forecast can change, but for now, it’s a flat spell.
Rusty, signing off.
