Alright folks, Rusty here. Let’s have a look at what’s coming down the line for our local stretch. To be straight with you, it’s going to be a slow grind for a while. The first proper recommendations don’t kick in until later, so we’ve got a solid stretch of quiet water ahead.
Right now, and for the next couple of weeks, the juice just isn’t there for a proper paddle. We’re looking at a long gap with no real standout surf. The first hint of something worth talking about doesn’t show up until the very end of the period, and even that is a long-range call, so keep the expectations in check.
Through Friday the 10th and Saturday the 11th of July, it’s pretty flat and messy. 3 ft swell from the SSW, but it’s coming with a cross-onshore wind that’s going to chop it all up. The combined wave energy is weak to moderate at best (475). Not your friend.
Sunday the 12th through to Tuesday the 22nd of July? More of the same story. Swell hovers around 1 ft to 3 ft, but the wind is often onshore or cross-onshore. The wave energy stays low, mostly under 500. Just not worth paddling out for, unless you’re desperate for a float.
Now, Wednesday the 23rd and Thursday the 24th? Still poor. Wind picks up and keeps things bumpy.
But here’s where it gets interesting. On Saturday the 25th of July we finally see a pulse. The swell bumps up to 6 ft from the S, with a period of 16 seconds—that’s a proper groundswell. The combined wave energy jumps to 1490, which is strong. The wind looks to be onshore but light, so it could clean up. This is the best on offer, but it’s a long way out, so treat it as promising but not a lock. Trestles (Lowers) is the spot for this, a beach and reef setup that’s very consistent. It’s exposed to the SW, and this S swell will wrap in nicely. Crowds are always an issue here, so expect company.
Because the swell is over 5 ft, this one’s for the advanced crew. Beginners should sit this one out. The water temp is about 67°, which is average for this time of year, nothing unusual.
So, the only real standout is that last day. Everything before that is a waiting game. Stay tuned, forecasts can change.
