The Lowdown
Alright folks, Rusty here. Let’s cut through the noise and look at what’s happening at Oceanside Harbor.
Straight up, we’re in for a bit of a flat spell to kick things off. The waves are tiny and the wind is messy, so don’t rush to wax up. The first real glimmer of hope shows up on Sunday the 26th of July, where we finally see some pulse in the water. Even then, it’s marginal, so keep your expectations in check.
The standout window looks like it’s shaping up around Monday the 27th of July and into Tuesday the 28th. The swell starts to nudge up to around 4ft from the SSW, with a period around 17-18 seconds. That’s proper groundswell, and it’ll have some push. The combined energy is moderate to strong (1132 in the morning on the 27th), so there’ll be some grunt behind the sets. Morning winds are light and offshore from the SSW, which means the lineup should be clean. Later in the day, the wind swings onshore, so the early sessions are the go. This is a beach/jetty setup, so the long-period swell might make it a bit straight and closey at times, but the jetty can line things up nicely.
The other potential highlight is Friday the 31st of July into Saturday the 1st of August. Swell bumps up to 6-7ft from the S, with moderate energy (2088 in the afternoon of the 31st). That’s getting solid, and it’s pushing into expert territory for sure. Winds are cross-onshore, so it’ll be a bit bumpy, but there’ll be plenty of water moving. The period drops to 13-16 seconds, which is still decent. If you’re an experienced surfer, this could be a session, but the onshore wind will keep it from being perfect.
Water temp is sitting at 73°F, which is much warmer than normal for this time of year. No need for a thick wetsuit, just a spring suit or even a rashie. Crowds are often an issue here, so expect company, especially if there’s any size.
Honestly, there’s nothing epic in the first week, and a lot of days are a write-off. The best advice is to target the mornings from the 27th to the 29th of July, and then keep an eye on the 31st of July to the 1st of August. After that, it fades back into small, weak slop.
Rusty.
