The Lowdown
Gather 'round, crew. Rusty here. I’ve been staring at the charts for the next couple of weeks, and honestly, it’s a tough one for us. The whole 16-day period is a flat spell, so you might want to wax up the longboard for a lake paddle or just take a break.
Let’s walk through it. From Sunday, the 2nd of August, right through to Monday, the 17th of August, there’s no real swell to speak of. The biggest bit of energy we see is on Wednesday, the 5th of August, with a combined swell energy of just 163 (moderate energy) – but that’s a messy 5 ft from the WSW with a short period of 7 seconds, and the wind is a fresh cross-onshore at 19 mph. It’s lumpy, choppy, and just not worth the paddle. The rest of the week is tiny, mostly under 2 ft, and the wind is either cross-on or straight onshore.
There are a few moments of glassy conditions, like on Saturday morning, the 8th of August, with a 0.3 ft swell from the W and a period of 9 seconds, and again on Sunday, the 9th of August, with a 1 ft swell. But that’s barely a ripple. Even the cross-off winds on the 2nd and 3rd do nothing for us because the swell is too small to push through.
The only break on the menu is Southerndown (Wales). It’s a beginner-friendly, fairly consistent spot, but the crowd factor is "sometimes" an issue. The water temperature is about average for this time of year. The swell is coming from the WSW, which is the optimum direction, but the swell height never gets above 5 ft, and the period is short, so the waves are weak and won’t hold shape.
Honestly, there’s no standout session here. The best I can say is that if you’re desperate for a paddle, the glassy mornings on the 8th, 9th, or 10th of August might give you a few ankle-biters, but it’s not surfing. It’s a blank run for the area, and it’s not unusual for this spot to go quiet for a stretch.
Rusty.
