The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Right, I’ll be straight with you – the next couple of weeks are looking pretty flat and ordinary for 10th Street (Avalon). There’s a real dry spell for decent waves. The first solid bit of surf to even get your hopes up doesn’t show until Saturday the 22nd, and even then, it’s not much. The swell energy is weak, only hitting about 75 (moderate energy), with a 4ft swell from the E. The period is a short 5 seconds, so it’ll be mushy and weak. The morning will be glassy, which is a bonus, but the quality is poor. After that, it’s right back to tiny, messy junkyard surf for the rest of the week.
Honestly, the middle stretch from the 24th to the 30th is a write-off. Swell heights hover around 1ft to 2ft, the combined energy stays in the doldrums (17 to 95), and the wind is mostly onshore or cross-onshore, chopping up anything that tries to form. The water temp is about average for this time of year, so nothing weird there.
Then, on Monday the 31st of August, we get a real kick. The swell jumps to 7ft from the E, with the combined energy roaring up to 378 – that’s moderate-strong energy. The period is short though, only 7 seconds, so it’ll be a bit lumpy. The morning looks clean with offshore wind, but that afternoon the wind swings onshore and chops it up. This is the standout of the whole 16 days. That 7ft is going to be too big for beginners, only for the experienced crew. The direction (E) isn’t ideal for this spot, which likes it from the NE, but the size and clean morning make it worth a look.
After that, it drops back to tiny stuff on Tuesday the 1st of September and beyond. Crowds at 10th Street are only sometimes an issue, so during the good window, you might have some company, but nothing crazy.
All in all, the only time you want to be in the water is the morning of Monday, August 31st. Everything else is a skunk.
Rusty.
