The Lowdown
Alright, surf’s looking pretty grim around these parts for a while. Honestly, for the next week or so, you might be better off finding a rock pool to stare into. The wave energy is just pathetic, and when there is a little bump, the wind’s usually messing it up. We’re in for a long stretch of flat, dribbly conditions.
The first few days, Wednesday and Thursday, are a total loss. Swell is tiny and there’s a fresh cross-shore breeze creating lumpy chop. Nothing to get excited about.
Then Friday the 11th rolls in with a bit of a pulse, but it’s weak. We’re looking at a modest 4ft on Friday morning from the North with a short 9-second period. The wind is offshore though, a gentle ESE, which is about the only positive. The wave energy is a weak 181. It’s rideable, but it’s going to be super ordinary, the kind of waves you take because you’re desperate, not because they’re good.
The weekend and the start of the next week are just flat. The swell drops right off, with nothing but ankle-biters through Monday. There’s a long gap here with no real surf on offer, from Saturday the 12th through to at least the middle of the following week. Just a lot of small, weak swells with short periods, blown around by moderate breezes. It’s a real drought.
Now, let’s talk about the water temp. For the first day we have a reading, it's 83° at Zampa. The anomaly is basically zero, so the water is exactly where it should be for this time of year. Warm and tropical.
Looking further out, there’s a serious change on the horizon. Around the 21st and 22nd, a solid, powerful swell is forecast to roll in. But here’s the catch: it’s going to be too big and blown out. We’re talking a severe gale with cross-onshore winds and a massive swell (23ft or more) with very strong wave energy (10,685 and higher). That’s when the ocean becomes a washing machine. For a reef break like Zampa (Inside), with that size and wind, it will be completely unsurfable and dangerous. This setup looks way more interesting for kite surfing than paddle surfing, to be honest.
There is a slight easing on the 23rd and 24th, with the swell dropping from a still-too-large 13ft down to a more manageable 7ft by Thursday the 24th. But the wind stays cross-onshore, making it messy and lumpy. It might be pushing the limits of what’s rideable, but it’s not going to be pretty.
So, the long and short of it is: there’s nothing on the immediate radar. The only real standouts are the dangerous, blown-out giant swells around the 21st and 22nd, which are for experts only and even then, they’re a pass. The small windows of clean, offshore winds are too small and weak to offer anything worthwhile. It’s a waiting game, folks.
