Alright folks, Rusty here. Let’s be straight with you – we’re looking at a long, dry spell for Zaga. The next couple of weeks are going to be a tough watch for anyone hoping to paddle out.
Right now and for the next 16 days, the surf is essentially flat. There’s nothing on the cards that’s worth getting wet for. We’ve got a solid stretch of days where the wave energy is zero (0), and even when a tiny pulse shows up on the 18th of July, it’s a weak 1 ft from the southwest with a short period of just 2 seconds and a combined energy of only 1. That’s barely a ripple. It’s so small and weak it’s not even worth calling surf.
The wind and conditions, to be fair, do look beautiful a lot of the time. You’ll see plenty of glassy mornings (14th, 16th, 18th, 20th, 27th July) and clean offshore breezes from the NW (13th, 15th, 21st, 22nd July). But without a swell to push into that clean water, it’s just a flat, pretty lake. Even the biggest blip we see is on the 18th afternoon, with a 1 ft cross-shore wind and the same weak energy. That’s not a surf session; that’s a float.
There are some more patches of tiny, inconsequential swell later on – a 0.3 ft from the southeast on the 24th of July – but it’s still rideable on a piece of paper, not a surfboard. This break is a rare-to-never-break spot, and this forecast confirms why. It’s a blank run that’s pretty normal for this sheltered corner. For diehards, keep an eye on the forecasts; things can change in a flash, but right now, there’s nothing to get excited about.
Rusty.
