The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Zaga over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s looking pretty bleak. We’ve got a long stretch of nothing, and I mean *nothing*, coming up. From now, clear through to the 17th of August, the swell is totally flat. There’s not a single wave to chase. It’s just poor surf conditions day after day. That’s a solid two-week gap with zero recommendations, which is a tough run. The only good news is that the water temp is sitting at about 81°, which is a touch warmer than normal for this time of year, so if you’re just floating around, it’ll be nice.
Now, finally, on the 18th of August, Tuesday morning, we might see a tiny blip. We’re looking at a 0.7ft swell coming from the SSE with a short period of 4 seconds. The combined energy is basically nothing at just (2). The wind is light and offshore from the NW, so the surface will be clean. But honestly, with that size and period, it’s barely a ripple. The afternoon stays poor with a 0.3ft, 7-second swell and a stiff cross-offshore breeze from the W at 16 mph, so don’t bother.
There’s no standout here, not even a good one. This is a spot that rarely breaks anyway, and this forecast is proving it. Keep the board in the car, but don’t hold your breath. Forecasts can change, so we might get lucky, but for now, it’s a solid miss.
Rusty.
