The Lowdown
Alright, Rusty here again, translating that into feet for you.
Let’s talk La Santa – The Slab. This is an expert reef break, no place for the faint of heart.
Water temp is about 75°F, which is roughly 3°F warmer than the usual for this time of year – a touch warmer than normal, feels nice.
The surf kicks off Wednesday, September 2nd, but it’s not great. Morning sees a 8ft swell from the NNE, period a short 8 seconds, with a fresh cross-off wind around 22 mph. It’s clean, but the quality is marginal. That’s expert-level size. Afternoon drops to 7ft, still short period. Wave energy is moderate (749 in the AM, 566 in the PM). Not the best start.
From Thursday the 3rd through Tuesday the 8th, it’s mostly flat or poor. Swell drops to 3ft to 6ft, period stays short (6-8 seconds), and the wind is cross or cross-off from the north. Wave energy ranges from 128 to 604, but the scores are all zeros – poor surf. That’s a six-day blank.
Tuesday the 8th morning has a 7ft swell from the north, period of 8 seconds, clean cross-off wind. Energy hits 781, but it’s still only a 1 out of 10. Not worth the paddle.
The real standout is Wednesday, September 16th. In the morning, a long-period groundswell from the NW at 12 seconds comes in at only 3ft. The wind is a light breeze from the NE, making it glassy and clean. Energy is weak (161), but that long period on a reef can create some real shape. It’s the cleanest window we get. Afternoon turns cross-shore and choppy, so forget that.
First week is a wash, second week only has that one glassy morning on the 16th. Crowds are often here, but with conditions this poor, you might have it to yourself.
Keep an eye on the 16th. Rusty out.
