The Lowdown
Alright folks, Rusty here. Let’s get straight into it. To be honest, for the next 16 days, we’re looking at a real flat spell. There’s no real surf on offer at all, so don’t get your hopes up for anything worthwhile.
We start off with absolutely nothing. Tuesday 1st September through to Wednesday 16th September is a total write-off. The swell is tiny, barely a ripple, with heights hanging around 0.3 ft to 4 ft. The energy is barely there, with combined swell energy readings mostly in the single digits or low double digits (like 13, 33, 39, 118 at its peak on the 9th), but it’s all messy, short-period windswell. The wind is mostly onshore or cross-onshore, making it choppy and bumpy. Even when we get a glassy moment on the morning of Sunday 6th, the swell is only 0.3 ft. There’s just nothing to work with.
The only spot we’ve got is Jupiter Inlet South Jetty, which needs a solid push from the NE to get going. But the few times the swell direction is right, the size is tiny and the wind is junk. The water temp is about average for the time of year, so no surprises there.
All in all, this is a 16-day stretch to do something else. Kite surfers might find a bit of fun in the stronger wind days, but for paddle surfing, it’s a total blank. The forecasts can always change, but right now, it’s flat as a pancake.
Rusty.
