The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's get into it.
Alright, look, I'm not gonna sugarcoat it. The next two weeks for Sebastian Inlet-First Peak are a real tough stretch. We're staring down a long, flat spell right out of the gate. The first few days are barely a ripple, with combined wave energy struggling to get above 20 (20) and 1ft slop from the east. That's not surf, that's a lake. We're looking at a dry run from Wednesday the 19th through to about Sunday the 23rd. You'll be better off checking the wind forecasts for a kite.
Sunday the 23rd afternoon sees a tiny bump of life, 2ft from the ESE, but the energy is still weak at 53 (53). It's surfable, but ordinary. The real glimmer of hope, the only standout in this whole sorry outlook, shows up on Thursday the 27th of August. We get a proper pulse of 2ft east swell, but the period jumps to 12 seconds, giving it some real push. The combined energy hits 130 (130), which is a solid, moderate wallop for this spot. The wind is clean offshore from the WSW, 12 mph. That's the call. The direction is a bit off the optimum, but with that period and clean wind, the inlet's lefts will have some shape. Friday the 28th is a follow-up day, 3ft from the ESE with a 10-second period, and again, clean offshore wind from the SW, 12 mph. Energy is 160 (160). That's your next best window. There's a water temperature anomaly, but it's pretty standard for this time of year, so no big story there.
After that, it fades back into the doldrums. The wind swings onshore and the swell dies. From the 30th of August onwards, it's a messy, choppy, and weak affair. We're looking at strong northerly winds and crumbling, short-period windswell, if you can even call it that. The last few days into September are just a write-off with onshore gales and tiny, weak energy. It's a tough run, but around here, forecasts can flip. For now, the only game in town is those two days late in the month.
Rusty.
