The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
To be straight with you, the first week or so is looking pretty average. We’ve got waves, but they’re small and the wind is mostly on it or cross-onshore, making things a bit lumpy. It’s not a complete write-off, but you’ll have to work for any half-decent runners. The water is a toasty 74°F — that’s a whopping 7°F warmer than usual for this time of year, so it’s truly unusual. You’ll be in boardies for sure.
The first real highlight doesn’t pop up until Friday, July 31st, and even then it’s a bit of a mixed bag. The standout potential is on Saturday, August 1st. That morning, Trestles (Uppers) is looking like the call. It’s a reef and point setup, very consistent, and you’ll get a solid 7 ft of swell from the S. The combined energy is strong at 1504, and with light offshore winds from the SSW at 6 mph, it’s going to be clean. The swell period is a bit short at 13 seconds, so it won’t have that long, grinding feel, but for a point break like Uppers, it should still line up nicely. This is definitely for experienced surfers only at that size.
Before that, on Thursday, July 31st, the afternoon sees a jump in size to 7 ft from the S, but the wind is a cross-onshore from the W at 9 mph, so it’ll be a bit choppy. The energy is high at 1584, but that wind will make it a struggle. Still, if you’re desperate, it’s something.
After that Saturday peak, the swell drops off quickly. Sunday, August 2nd, still has some 5 ft waves in the morning, but the conditions turn poorer. From Monday, August 3rd, right through to Friday, August 7th, it goes flat and weak. The combined energy drops to a paltry 140-365, and the swell heights are below 3 ft. There’s a long gap of poor surf for several days there. It’s a bit of a bummer, but that’s the way it goes sometimes.
The best bet in the whole window is that Saturday morning (August 1st) at Trestles (Uppers). Get it while you can.
Rusty.
