The Lowdown
Alright, this is Rusty comin' at ya from the sand. Let's have a look at what the next couple of weeks have in store for us.
We're lookin' at a pretty drawn-out stretch of small, average conditions here. The first real pulse of surf worth paddlin' out for isn't until the 23rd of July, but even then, it's a bit of a struggle. The wind is mostly cross-on or onshore for the first week, which is gonna keep things a little messy. The water temp is about what you'd expect for this time of year, so no need for a thick suit.
The standout window, and the only time I'd really get excited, is the morning of the 1st of August. We finally see a bump in size with a S swell pushin' 6 ft, and the combined energy hits a solid 1392 (moderate wave energy). The wind is a light cross-on from the WSW, so it ain't glassy, but it's gonna be a lot more fun than what we've been dealt. The swell period is a middling 13 seconds, so it's a bit of a mix. For a wave as good as Trestles (Uppers), it's the best bet on the table. That afternoon holds similar size at 6 ft, so you could get a solid session in.
The rest of the period is pretty grim. From the 23rd through the 31st, the swell is tiny, often under 3 ft, with combined energy values mostly under 1000. The scores are bottomed out, and the surf conditions are described as poor or marginal. There's a lot of light cross-on breeze, which just adds a bit of texture to an already small wave. Then, after the 1st of August, it drops right off again into a long, flat spell. From the 3rd of August onwards, the swell drops to under 3 ft, with energy levels barely crackin' 200, and it's all labeled "poor surf conditions." The 7th of August has a long-period 18-second swell, but it's only 2 ft, so it's just a ghostly pulse on the tide. That's a gap of several days with nothin' worth a look.
So, if you're after a wave, circle your calendar for the 1st of August. It's the only time the numbers really come together. Everythin' else is a wait-and-see or a session for the longboard if you're desperate.
