The Lowdown
Hey, it's Rusty. Let's talk about Surfside Jetty. This spot's an advanced wave, and it's inconsistent – it doesn't fire often, and when it does, it's usually crowded. Over the next 16 days, from July 19 through August 3, the surf outlook is pretty grim. The first few days are a write-off: Sunday the 19th is flat with poor conditions, and Monday the 20th offers only a tiny 2.6ft SSW swell that's marginal at best. The water temperature on the 19th is 69.6°F, which is much warmer than normal for this time of year – that's a 4°F anomaly.
The best windows are slim. Saturday morning July 25 brings a 2.3ft SW groundswell with a very long 21-second period. The combined energy is moderate (822), and winds are light cross-onshore at 6 mph, so it'll be clean but small. That long period means the waves will have shape, but at a jetty it might be a bit straight. The other standout is Saturday morning August 1 – a 3.6ft SSW swell, 14-second period, moderate energy (824), again with light cross
