The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook is a tough one. We’re lookin’ at a 16-day stretch for our area, and honestly, the surf is flat, real flat, for the entire run. There’s not a single decent wave on offer, so I can’t point you to a standout session. The whole forecast is basically a write-off.
Right now, through the end of July and all through August, up to the 14th, the swell is tiny and the energy is weak. The water temp is sittin’ at 86°F – that’s about average for this time of year, so no surprises there, but it’s the only thing that’s normal.
The first few days, from Thursday the 30th of July through the weekend, we’re seein’ swell heights of just 0.3ft to 0.7ft, with periods mostly under 10 seconds. Blame the wind, too – it’s all over the place. Saturday morning the 1st of August has a glassy moment with a light WNW breeze at 3 mph, but there’s only 0.7ft of bump. It’s clean, but it’s tiny. The combined energy never gets above 14 over that stretch, which is weak.
We roll into the first week of August, and it’s more of the same. Monday the 3rd, Tuesday the 4th, the swell barely nudges up to 1ft, but the wind is mostly cross-onshore or onshore, messin’ up what little shape there is. The energy values are still in the teens and low twenties – weak stuff. A few days, like Thursday the 6th, the swell hits 3ft, but it’s a short-period windswell from the ESE with a period of just 4 or 5 seconds, and the wind is blowin’ straight onshore at 12 mph. That’s not surf, that’s a washing machine. The combined energy does climb to 38, but it’s terrible quality.
The second week doesn’t get any better. From the 8th through the 14th, we’re stuck with tiny swell, 0.3ft to 2ft, and the wind stays messy. The best we get is a little 1ft bump on Wednesday the 12th with a light cross-offshore breeze from the SW, but the swell is from the S with a period of 4 seconds – just a ripple. The energy stays low, mostly in the single digits or low twenties.
So here’s the deal: if you’re itchin’ to paddle out, you’re gonna be disappointed. This is a blank run for the area, and it’s not unusual for this spot to go quiet. The forecast can always change, but right now, I’d say leave the board in the garage and maybe go for a swim. The only thing that might hold some interest is if the wind picks up – this setup looks more interesting for kite surfing than paddle surfing, but that’s a different story.
Rusty.
