The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch for Sebastian Inlet-Third Peak. The whole 16-day window is looking pretty flat and uninspiring. We’ve got a long gap of small, weak surf with not a single standout day. The combined wave energy barely cracks double digits for most of the first week, sitting at a paltry 20 (weak energy) to start, and only picking up slightly later. That’s just not enough to get excited about.
For Wednesday the 15th, we’re looking at tiny 1 ft swell from the NE with a short period of 7 seconds. The wind is a light cross-off, so the surface will be clean, but there’s just no power. It’s the same story through Thursday and Friday the 16th and 17th – swell drops to 0.7 ft, and energy is down to 9 (weak energy). The water temperature is about average for this time of year, so no drama there.
We do get a small bump on the 22nd, with the swell pushing up to 2 ft from the ESE, and the combined energy jumps to 56 (weak energy). The period is still a short 7 seconds, so it’s gonna be a bit crumbly. The afternoon winds swing cross-shore, but it’s still not anything to write home about.
The second week, from the 24th onward, the swell hovers around 1 ft to 2 ft from the E, with barely any period. The combined energy stays in the 20-34 range (weak energy). The real bright spot is the morning of Sunday the 26th – we get a glassy, 2 ft swell from the E, but with a short 7-second period. It’ll be clean, but it’s just not enough to call a standout.
Honestly, there’s no good surf on offer here. This is a flat spell. If you’re a surfer, you’re gonna be doing something else. With that tiny swell and the beach/jetty setup, it’s more interesting for the kite surfers if they can catch a puff of wind. The forecast can always change, but right now, it’s a long blank run.
Rusty.
