The Lowdown
Alright, Rusty here again. Let’s talk about 10th Street (Avalon) in feet and Fahrenheit.
It’s a beach/jetty break that’s known for being inconsistent, so don’t expect much for a while. We’ve got a long dry spell starting from today (August 20th) and stretching all the way through the end of the month. Swell is tiny, rarely over 1ft, coming in with short periods around 8 seconds or less. The combined energy is weak, often below 100, and the winds are messy — cross-on, cross-off, onshore. Even on cleaner days like Sunday morning with light winds, we’re only looking at around 1ft. Not worth suiting up.
This flatness holds right into early September. On September 1st, the swell bumps to 4ft to 5ft, but the period is short (5 to 6 seconds) and the wind stays onshore or cross-on. The energy climbs into moderate territory (100 to 181), but the surf quality stays poor. That setup might be more interesting for kite surfers than for anyone with a paddle.
The real action starts on Thursday, September 3rd. By Thursday morning, the swell hits 6ft from the east with a 9-second period, and the wind is cross-off from the north — clean. Thursday afternoon is the highlight: 6ft from the east, light offshore wind from the northwest, and the combined energy jumps all the way to 895. That’s strong, powerful surf. Still good for intermediates, but with plenty of punch.
Then on Friday, September 4th morning, we get glassy conditions — absolutely no wind — and 6ft east-northeast swell. The energy stays strong at 704. That’s about as clean as it gets for this spot. Just remember, 10th Street is inconsistent, so when it fires, you don’t want to miss it. By Friday afternoon, the wind swings onshore and the quality drops.
Water temperature is 77°F, which is a touch warmer than the usual for this time of year. That’s a nice little bonus.
So, the takeaway: you’re waiting through a long flat gap until the very end of the first week of September. The standout days are September 3rd afternoon and September 4th morning. Be there.
Rusty.
