The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Southerndown over the next couple of weeks.
Right off the bat, I’ve got to be straight with you – the first week and a half is a tough slog. We’re looking at a long dry spell until we get a proper window. The water temperature is sitting at 69°F, which is a massive 8°F warmer than normal for this time of year – that’s way out of the ordinary, a real tropical treat for the UK.
The first proper chance of a wave doesn’t show up until Monday the 7th of September. The morning is looking good with a glassy 4ft swell from the WSW, 11-second period, and the wind is dead calm. The combined energy is moderate (343). It’s a promising start, but the swell is small and the afternoon drops off. It’s really just a tease.
The standout of the whole forecast is Thursday the 10th of September. That morning, Southerndown is firing. We’ve got a solid 7ft swell from the WSW with an 8-second period, strong energy reading (885), and a light ESE breeze – that’s clean conditions. This is proper size, but it’s not beginner territory; over 8ft it gets gnarly, and this is close. For those with some experience, this is the session to aim for. The afternoon holds similar size at 8ft, but the wind swings cross-shore, so the morning is the pick.
After that, the surf fades again. Friday the 11th has a glassy afternoon with a 3ft, 9-second swell, but it’s small and weak. The rest of the forecast into the second week is a mix of tiny, wind-affected waves and choppy conditions. The 12th and 13th of September show nothing worth paddling out for.
So, to sum it up: you’ve got a long wait. The first real hope is the 7th, but the absolute standout is the morning of the 10th of September. That’s your one. Circle it.
Rusty.
