The Lowdown
Alright, this is Rusty. Let’s have a look at what’s cooking for the next couple of weeks.
Honestly, the first week is a bit of a write-off. We’re looking at a long stretch of mediocre conditions, with the first real flicker of hope not showing up until much later. The water is abnormally warm right now, sitting at 72° with a 6° anomaly, which is very unusual for this time of year.
The first chance for anything decent comes late on Thursday, July 23rd. The standout is 15th Street. It’s a consistent beach and reef setup, exposed to the swell, and it’s usually pretty crowded. On Thursday morning, July 23rd, we’ll see a solid 7ft S swell with a period of 14 seconds and a very strong combined energy of 1659. The wind will be light from the WSW, almost offshore, which should keep it clean. That’s a fair bit of size, so this one is for the experienced crew only. The conditions are marginal, but the energy is there.
The quality holds into Friday, July 24th, with a 6ft S swell, period 14 seconds, and the wind staying light offshore from the WNW. The energy is still strong at 1444. It’s still a bit of a gamble on the tide, but it’s easily the best window of the whole forecast.
After that, it fades back into smaller, less promising surf. The rest of the period is a mix of small, weak swells and cross-onshore winds, so don’t get your hopes up for a second pulse.
So, the play is clear: if you’re an expert, circle Thursday July 23rd and Friday July 24th on the calendar. It’s the only real window of power in an otherwise flat and messy outlook.
Rusty.
