The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for South Del Mar.
It’s a pretty quiet stretch ahead, folks. We’re looking at a long patch of marginal to poor conditions, so don’t expect much action for a while. The first few days are a write-off, with small, weak swell and even the good wind direction can’t save it. There’s a gap from the start right through to the end of the first week where you’d be better off doing something else.
Now, the one real standout that’s worth circling on the calendar is Sunday the 6th of September. That afternoon, South Del Mar finally gets a pulse. We’re talking a solid 8ft swell from the south, with a period of 15 seconds – that’s a proper long-period groundswell full of energy. The combined energy hits 2858, which is very strong. The wind is a clean cross-offshore breeze out of the north at 16 mph, so the surface should be clean. This is a big swell, over 8ft, so this is strictly for the experienced crew. This reef break can handle that size, and with that south swell direction, it’s lining up nicely. Water temp is about average for the time of year, so nothing unusual there.
The Sunday morning is also sizable at 8ft from the south, but with a cross-shore wind, it’ll be a bit messier. Still, it’s an option for the brave.
After that, the swell drops off fast. Monday the 7th is still big but the wind swings around and makes it ugly. By Tuesday, we’re back to small, weak dribble. The rest of the second week is pretty flat or poor, with nothing really worth paddling out for. There’s a little bump of energy around the 10th and 11th, but it’s small and the wind isn’t kind. It’s a long, quiet end to the outlook.
So, to sum it up: if you’re an advanced surfer, Sunday the 6th afternoon is your best bet. For everyone else, it’s a waiting game.
Rusty.
