The Lowdown
Alright, let’s talk about Zaga. I’m looking at a long stretch here over the next 16 days, and to be honest, there’s not a whole lot to get excited about for a paddle surfer. The first real recommendation doesn’t show up until the very start of the period, but even then, it’s a pretty flat start. The water is sitting at a balmy 83°F, which is 5°F warmer than usual for this time of year, so you’ll be swimming in bathwater if you go for a float.
The first bit of any surfable pulse is on Wednesday the 9th of September. We get a tiny 0.3ft SE swell creeping in with a period of only 4 seconds, and zilch for energy. That’s barely a ripple. The wind is glassy in the morning, so it’ll be flat and clean, but there’s nothing to ride.
The next glimmer is on Monday the 14th of September. The morning shows 1.0ft from the SE, period 4 seconds. The wind is cross-off, so it’ll be clean, but again, we’re talking about tiny, weak waves. The afternoon drops to 0.7ft with 3 seconds. Not worth suiting up for.
Tuesday the 15th of September morning offers the biggest wave in the whole outlook: 1ft from the SE, period 4 seconds. Light breeze, clean conditions. That’s about the high point, and it’s still less than knee high.
After that, we get dribbles on Wednesday the 16th and Thursday the 17th – 0.3ft and 0.7ft, then on the 17th afternoon a 2ft wave shows up from the SE with a period of only 3 seconds. The period is super short, so it’ll be weak and crumbly. Winds are cross-off, so at least it’ll be clean, but there’s no power behind it.
The overall pattern here is a pretty blank run. Zaga is a sheltered, rarely-breaking beach and point, and for this 16-day window, the swell just isn’t making it in. There are long gaps of days with zero surf at all – from the start through until the 9th, then another dry spell until the 14th. If you’re a beginner and just want to bob around in clean, glassy conditions, the morning of the 7th and 8th of September look lovely with no wind, but there are no waves. For a proper surf, it’s a no-go. Forecasts can change, but right now, there’s nothing to paddle for.
As for the biggest standout? The 2ft on the 17th afternoon is the biggest, but it’s still tiny and gutless with a 3-second period. Look, if there were significant swell with poor quality and strong cross-winds, I’d say it’s more for kites, but here we just have no swell. Keep the board in the car, and maybe check back in a few days.
