The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Southerndown over the next couple of weeks.
Right off the bat, I’ve gotta be straight with you – this is a tough one. The whole 16-day window is looking flat and lifeless. There’s no real swell to speak of at any point. The surf stays poor from start to finish, with the biggest wave heights barely scraping 3 ft, and even that is on a short, weak period.
We kick off Thursday, 30th July with a tiny 2 ft from the west and a period of just 5 seconds; combined energy is a measly 35. The wind is a cross-onshore, so it’s choppy and messy. Friday and Saturday are more of the same – small, weak, and cross-onshore. The swell height actually drops to 1 ft on Friday morning, with energy bottoming out to 12.
Sunday, 2nd August, things get a bit cleaner. The wind swings cross-off at 6 mph, and the swell shifts to the WSW with a period of 8 seconds. But the size is only 1 ft and the energy is 13. It’s clean, sure, but you’d be lucky to get a ripple. Monday and Tuesday carry on the same story: clean conditions with cross-off winds, but the swell is tiny – 1 ft at best – and the energy sits between 14 and 31.
By the time we hit Wednesday, 5th August, the swell has vanished. We’re looking at 0.7 ft with a 7-second period and energy down to 7. It stays like this for the remainder of the outlook. From the 6th through to the 14th of August, we get some offshore winds, a few glassy moments, and clean conditions, but the swell is a joke – 0.3 ft to 0.7 ft. The combined energy drops to single digits, even hitting 1 on the 10th of August. The water temperature is about average for this time of year, so no surprises there.
There is absolutely no standout window here. No day offers a recommendation. The only positive is that the wind is often clean, but with no swell, you’re not surfing. If you’re a kite surfer, the stronger winds on the 8th and 9th of August (25 mph offshore) might look interesting, but for a paddle surfer, this is a total write-off. It’s a blank run, and for Southerndown, that’s not unusual when the Atlantic is quiet.
Rusty.
