The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for our local stretch.
Honestly, the next week and a half are pretty lackluster for Austinmer Beach. We’ve got a long gap of small, weak, and messy conditions staring us down until the end of the month. The first real glimmer of something decent doesn’t pop up until Friday morning, August 28th, and even that is just ordinary surf. The standout is going to be Friday afternoon, August 28th and then Saturday morning, August 29th.
Friday afternoon, August 28th is the pick of the whole outlook. We’ll see a clean 5 ft swell from the south with a period of 9 seconds, and it’s going glassy. The combined energy hits a solid 549 (moderate wave energy), and with that kind of wind, the waves will be clean and lined up. It’s an exposed break, so it’ll pick up that south swell well. The water temp is around 64°, which is pretty normal for this time of year. No crowds to worry about, either.
Then Saturday morning, August 29th is the one for the bigger gear. The swell bumps up to 6 ft from the SSE, still a 9-second period, and we’ve got a solid offshore wind from the west at 9 mph. That offshore flow will groom it beautifully. Combined energy is up to 599 (moderate wave energy), so there’s some real push behind it. This is a beginner-friendly break most days, but 6 ft is pushing the limit for learners—more fun for the experienced crew.
After that, things get ugly fast. Sunday, August 30th brings a massive jump in swell—8 ft on the Sunday morning with strong winds, and by Sunday afternoon it’s a dangerous 16 ft from the ESE. The combined energy skyrockets to 3561 (very strong wave energy). The wind is a mess: cross-shore and onshore. For a beach break like Austinmer, this setup is less about surfing and more about watching the ocean roar. It stays too big and messy through to the end of the forecast on September 2nd, with 10 ft+ swells and strong winds. That’s strictly for the hardcore, if anyone’s mad enough to paddle out.
So to sum it up: you’ve got one proper window—Friday afternoon, August 28th, and Saturday morning, August 29th. That’s it. Everything before is small and sloppy, and everything after is too big and blown out.
Rusty.
