The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Sebastian Inlet-First Peak over the next couple of weeks.
Honestly, mate, it’s a pretty flat and quiet run ahead. The whole 16-day window is a struggle. There are no real standouts, no days you’d circle on the calendar. The first actual hint of anything surfable doesn’t show up until Thursday the 20th of August in the morning, and even then it’s only a 2ft swell from the E. The combined energy is weak at just 88, so it’s not going to have any push. That morning does have light cross-offshore winds keeping it clean, but the wave height is tiny. That’s really the only chance to get wet without it being a total mission.
Before that, from now all the way through Wednesday the 19th of August, it’s a write-off. Swell heights are mostly below 1ft, periods are short, and the combined energy barely cracks 50 most days. Winds are all over the place, too—cross-shore, cross-on, even some onshore stuff. Not worth paddling out for.
That Thursday the 20th morning is the pick, but it’s a marginal one. The water temp is about average for the time of year, no big anomaly to report. The swell direction is E, which matches the optimum NE direction closely enough, but at 2ft and 10 seconds of period, it’s more of a grovel session than anything with real shape.
After that, it drops right back off into poor conditions again through to the end of the window. By Wednesday the 26th of August, there’s a morning with glassy conditions and no wind, but still only 1ft of E swell. Just not enough to work with.
Look, there’s nothing here that’s going to get the heart racing. For a spot that’s usually very consistent, this is a real dry spell. Keep an eye on the charts, because it tends not to stay this flat for long.
Rusty.
