The Lowdown
Alright, Rusty here. Let’s have a good, hard look at what’s on offer for the next couple of weeks.
Honestly, it’s a flat spell for us at Sebastian Inlet-First Peak. We’re staring down the barrel of a long, drawn-out period of tiny surf. The good news is there are a few moments where the conditions line up, but don’t expect much push. The water’s sitting at 83°F which is about two degrees cooler than usual for this time of year – not a big deal, just a touch of refreshment.
We’ve got a real dry run from now until the middle of next week. Morning conditions are often the cleanest with light or offshore winds, like the WNW breeze on the morning of the 12th, but the swell is basically non-existent at 0.7ft. That low energy is reflected in the combined energy readings, which are mostly below 30 – that’s weak. We’ll see some tiny bumps of 1ft to 1ft from the east, but the period wanders between 6 and 13 seconds. A longer period of 13 seconds on the afternoon of the 14th sounds good in theory, but with only 0.3ft of swell and a moderate combined energy of just 19, you’d be waiting for a set that never really shows. The offshore winds on the morning of the 16th and the glassy conditions on the morning of the 18th will make for perfect looking water, but there’s just no wave to ride. It is what it is.
We do get a tiny uptick around the 19th – the combined energy finally pushes past 30 on the 19th morning to 34, with a 1ft east swell at 10 seconds. The morning winds are a light cross-off from the south, so it’ll be clean. The afternoon of the 19th sees the combined energy hit a moderate 100 (100), with a 2ft southeast swell at 10 seconds. That’s the best size we’ll see in this whole window, but the onshore wind gets messy with a moderate cross-shore from the ESE. That’s the stand-out moment, but it’s still small and choppy.
After that, it’s back to the doldrums. We’ll get glassy mornings on the 20th and 21st and a tiny 1ft swell from the east. The 24th and 25th see a bit more easterly pulse, but the wind turns onshore. The last few days of the month have that same story: clean mornings with tiny swell and onshore afternoons. For a spot that’s *very consistent*, this is a frustrating run. For the absolute best of a bad bunch, I’d say the Wednesday morning of the 19th of August is your best bet – it’s clean and has the highest combined energy for a morning session, but keep your expectations low.
Seriously, with this combination of tiny, weak swell and mostly grovelly conditions, this stretch looks more interesting for a kite surfer than a paddle surfer. It’s a quiet period for a typically reliable break.
Rusty.
