The Lowdown
Alright folks, Rusty here. Let's be straight with you – this 16-day outlook for 15th Street is a tough one. We’ve got a long, quiet stretch ahead before anything worth paddling out for shows up. The first real recommendation doesn't roll in until the 14th of August, so there's a big gap of days with nothing to get excited about.
The waves are tiny and the wind is all wrong for most of the run. You’re looking at poor surf conditions day after day with light breezes and cross-onshore winds messing up what little bump there is. The water is running at 76°F on the first day, and the anomaly of 8°F means it’s much warmer than normal for this time of year – a nice bonus if you're just floating around, but it won't help the surf.
The first real glimmer we get is on the afternoon of 14th August (Friday). The swell starts to bump up to 2ft from the SW, and we get moderate wave energy (625). It's still listed as marginal due to questionable tide conditions, so don't expect perfection, but it's the first thing worth a look. The wind is onshore from the W at 9 mph, which isn't ideal, but it's manageable.
Then, 15th August (Saturday morning) shapes up as the standout of the entire outlook. The swell gets a little more push, hitting 4ft from the SW with a combined energy value of 658 – that’s moderate to strong energy for this break. The wind is from the W at 9 mph and straight onshore, so it won't be glassy, but the size and energy are a step up from everything else. At 4ft, it’s small enough for beginners but has enough push for a fun longboard or a grovel board session.
The rest of that second week is more of the same: small swell, 2ft to 3ft, and onshore winds. Nothing else comes close to that Saturday morning bump. It's a lean forecast, but that one morning on the 15th is your best bet if you're desperate for a paddle.
Keep an eye on it, but don't hold your breath.
