The Lowdown
Alright, let’s be honest with each other. Right now, looking through the whole 16-day window for Anna Maria Key, it’s pretty grim. We’ve got a run of days with no surf to speak of, and what little swell shows up is so weak and short-period it’s barely worth paddling out for. The first couple of days are a write-off, and the pattern doesn’t really change for a long stretch.
From Wednesday the 12th all the way through, it’s a desert. We’re talking days of zero energy, with the combined swell energy reading 0. There’s a few mornings like Friday the 14th where it goes glassy – that’s nice to look at – but with swell at 0.3 ft and a period of 4 seconds, it’s flat. You’d be floating. Even when we get a tiny bump, like on Monday the 17th afternoon with 2 ft from the WNW and a period of just 3 seconds, the combined energy is only 6. That’s weak. Plus, the wind is usually cross-onshore or onshore, chopping it up.
The water temp is sitting at 86°F, which is pretty normal for this time of year – warm bath water.
Honestly, the whole set-up here is a beach/pier break that’s exposed, but there’s just nothing doing. If you’re desperate, the absolute best of a bad bunch might be the morning of Wednesday the 19th – 0.7 ft from the WNW, 5-second period, with a light cross-onshore breeze. But that’s not a recommendation, that’s just the least awful thing on the list. The rest of the window, including another tiny 0.7 ft WNW pulse on the 26th, is just more of the same: tiny, weak, and messy.
For a spot that’s fairly consistent, this is a proper dry spell. It tends not to stay this poor for long, but for now, leave the board at home. For paddle surfing, there’s nothing here. If the wind kicks up, it might look more interesting for kite surfing than anything else.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Anna Maria Key may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
