Alright mates, Rusty here. Let’s break down what Oceanside Harbor has cooking for the next couple of weeks.
Right off the bat, we’ve got a long dry spell. The first chance for a wave is Thursday afternoon, but it’s a real “maybe” situation. Swell is a tiny 3ft from the SSW with a long 16-second period, giving us a combined energy of 568. That’s decent energy for the size, but that long period groundswell is fussy – it likes a point or reef, not a beach/jetty. The water is sitting at 69°, which is a touch warmer than usual for this time of year.
The next few days are a total washout. Friday the 10th through Sunday the 13th are all poor to marginal. Tiny 3ft swell, and the wind is onshore or cross-onshore, just chopping everything up. It’s a slog.
Then it gets even worse. From Monday the 14th through Friday the 17th, the swell drops to a pathetic 1ft to 2ft. Combined energy numbers are in the 200-300 range, which is barely enough to move a sea gull. There’s a tiny blip on the 18th with a 3ft SW swell and energy jumping to 710, but it’s still cross-onshore and marginal.
Now for the one real highlight. Fast forward to the second week. The afternoon of the 18th of July shows a better pulse: 4ft from the S, 16-second period, and combined energy jumping to 1077. That’s moderate energy starting to build.
But the best window is clearly Sunday the 19th of July. We’ve got a 5ft SSW swell in the morning with a 14-second period. The combined energy is a solid 1391. For a beach/jetty, that’s a proper fun size, but at 5ft it’s getting too big for beginners. The wind is a light onshore breeze, keeping things clean enough. This is the one to watch, but it’s a long-range forecast, so don’t book the day off work just yet. The 20th and 21st are still holding 3ft SSW swell with moderate energy, but nothing like that Sunday punch.
After that, it’s all downhill again. The 22nd onward is back to small, cross-onshore 3ft to 3ft slop, with combined energy dropping below 500. Not worth the drive.
So, the bottom line: the first week is a flat, frustrating bust. The only real standout is that Sunday the 19th, with a decent swell and reasonable conditions. That’s your one shot in this entire 16-day window.
Rusty.
