Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Gotta be straight with you, this 16-day stretch is looking pretty flat and frustrating for the most part. We’re in for a long, quiet spell. The main focus is on Trestles (Lowers), and honestly, it’s a tough watch.
The water’s sitting at about 68.5°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing your arse off while you’re waiting for a wave.
Right now, through the first few days, it’s pretty grim. We’ve got tiny swell, mainly from the SSW, and the wind is all wrong. It’s mostly a cross or cross-onshore breeze, making everything lumpy and messy. It’s just not worth paddling out for.
The best of a bad bunch, and I mean the only real glimmer of hope, comes around Tuesday the 7th and Wednesday the 8th of July. We finally see a bit of a pulse, with the swell building to about 3.6 ft from the SSW. The combined energy climbs into the moderate range (over 800 units) which is something. The real kicker here is the wind: Tuesday and Wednesday mornings we get a light SW breeze, which is actually offshore for Trestles. That’ll clean the faces right up. It’s still not big, but with that offshore wind and a long period around 18 seconds, those waves are going to have some real power and shape. You’ll get proper, grinding lines down the point. Crowds are always an issue at Lowers, so expect a full lineup even for this small window.
After that pulse, it’s back to the doldrums. From the 10th of July right through to the 19th, the swell drops off again, the wind turns crap again, and we’re back to barely rideable slop. The energy just drains away.
There’s a tiny flicker of hope on Saturday the 18th of July, with a morning offshore wind again, but the swell is only about 2.6 ft and it’s coming from the SW, which isn’t the optimum direction for the spot. It’s a long way out, so don’t bet the farm on it.
Overall, if you’re dying for a wave in the next couple of weeks, your window is tiny. Pin everything on that Tuesday and Wednesday morning session the 7th and 8th of July. Get there early, be ready for a crowd, because that’s the only time we’re going to see anything clean. Otherwise, it’s a long wait for a wave.
