The Lowdown
Alright, grab a coffee, let’s talk surf at Surfside Jetty.
Honest truth? It’s a grim stretch ahead. The whole 16-day run is a write-off, no real standouts to get excited about. The swell is tiny, nothing gets above 3 ft, and the direction is mostly SSW or SW which isn’t ideal for this spot – it prefers a W swell. The period is all over the place, going from a sluggish 11 seconds up to a very long 19 seconds on the 28th, but that long-period energy is wasted on the poor size and wonky wind.
From now until the 28th of August, it’s the same story every day: poor surf conditions. The winds are nearly always onshore or cross-onshore. It’s choppy. Honestly, even the mornings with light breezes and onshore winds look flat and messy. The combined energy stays weak to moderate for most of it – not enough to push anything rideable.
Around the 28th there’s a tiny flicker of something – a marginal forecast for the morning with 3 ft of SSW swell and a very long period of 19 seconds, and some decent energy. That’s about it. The wind is light and onshore, so it could be glassy, but with that size, it’s going to be weak and inconsistent. Definitely not a standout.
The morning of the 29th is similar: 3 ft, 17 seconds period, with light onshore wind. That is the absolute best on offer in this entire forecast window. Even then, you’re looking at marginal conditions with questionable tide. The afternoon gets blown out by cross-onshore winds.
After the 29th, it just fades back to flat and choppy. The 30th has 3 ft again but it's cross-onshore by morning, and then strong onshore wind. And by the beginning of September it’s back to nothing.
The water temperature is around 69°F, which is a touch warmer than normal for this time of year – that’s the one nice thing you’ll feel when you’re out there bobbing around.
Bottom line: if you’re a paddle surfer, leave the board at home. The wind and swell combo might make this more interesting for the kite crew on a few of the afternoon breezy days, but for a surf, there’s nothing here. Long-range outlooks can change, but as it stands, it’s a blank run.
