The Lowdown
Alright folks, Rusty here. Let’s get straight into what’s happening for Anna Maria Key.
Right off the bat, I’ve got to be straight with you – this 16-day window is looking flat as a pancake. We’ve got a long stretch of nothing happening. The first real sign of any rideable bump doesn’t show up until the morning of Wednesday, August 19th, and even then, it’s barely a ripple. The good news is, for a beach/pier setup like this, it doesn’t tend to stay this poor for long, so don’t write the whole month off just yet.
So, let’s break it down. There’s absolutely nothing on offer for the first week and a half. From Tuesday, August 11th, right through to Tuesday, August 18th, it’s all “poor surf conditions” with zero energy. You’ll see some glassy mornings, like the 11th and the 14th, with clean, calm conditions, but not a single wave to ride. The water temp is sitting at a warm 86°F, which is about average for this time of year, so at least a swim wouldn’t be a shock to the system.
The first real tease comes on Wednesday, August 19th. The morning session is a cross-on breeze from the WNW at 9 mph, with a tiny 2 ft swell from the West. The period is a poor 4 seconds, so it’s just wind chop. The combined energy is a weak 6 – barely enough to get your board wet. The afternoon is a bit better, with a 2 ft swell from the West and a period of 5 seconds, pushing the combined energy up to 11. Still, the wind is onshore from the West at 12 mph, making it messy. This is the best we’ve got, and it’s not saying much. It’s really only for the most desperate.
Thursday, August 20th, is more of the same. A morning swell of 2 ft from the West (period 4 seconds, energy 10) with onshore wind. The afternoon fades a bit to 1 ft. The wind is still poor. After that, it dribbles away into nothing again. The 23rd shows a tiny, glassy 0.3 ft swell from the NW, but it’s a long shot.
Look, if you absolutely need to get wet, Wednesday, August 19th afternoon is the only time you might find a knee-high, lumpy wave. The optimum swell direction for this spot is from the NW, and we’re getting some West swell, so it’s close, but the wind is just going to ruin it. Crowds are “often” here, but with this tiny surf, even the hardcore won’t be out. It’s more of a kite-surfing breeze than a paddle-surfing day.
Stay tuned, forecasts can change, but right now, the only thing we’re catching is a suntan.
Rusty.
