The Lowdown
Alright crew, Rusty here again. I’ve been staring at the numbers for Sebastian Inlet-First Peak, and the outlook is a tough one. We’ve got a long, flat spell stretching out over the next 16 days.
Right now, through late August and into the first week of September, the swell is tiny. We’re talking knee-high at best, usually 0.7 ft to 1 ft, with most of the energy barely registering—the combined energy is mostly under 100 (10 to 95). The wind is a problem too, coming onshore or cross-on from the ENE and ESE most of the time, chopping up what little ripple there is. There are a few glassy mornings, like on 28 August and 4 September, but with swell heights around 0.7 ft to 2 ft, you’d be on a log fighting for any kind of glide.
There’s a slight lift around Monday afternoon the 7th of September and into Tuesday the 8th. We finally see some moderate energy—141 on the afternoon of the 7th—with a 0.8 m (3 ft) swell from the NE. That’s the biggest push in the whole forecast. The period is around 9 seconds, so it’s a short-period windswell, not a groundswell. The catch is the wind is still blowing onshore at 15–20 mph. The wave energy is there, but it’s going to be a bumpy, blown-out mess at the jetty. Wednesday the 9th morning holds similar energy (109) with 0.7 m (2 ft) and straight onshore wind.
If you really want to paddle out, that Monday afternoon to Wednesday morning window is your only real shot, but don’t expect anything clean. The water temp is about where it should be for this time of year.
Overall, it’s a long stretch of poor conditions. No real standouts to get excited about.
Rusty.
