The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cookin’ at Anna Maria Key.
To be brutally honest, this is about as flat as a week-old beer. We’ve got a 16-day window staring at us and there’s simply no rideable swell to get excited about. The combined energy readings stay stuck on 0 most days, and even the rare bits of movement barely tickle 1 or 2 – that’s basically zero wave energy. The swell that does show up is tiny, with heights hovering around 1ft, and the periods are a pathetic 2 to 4 seconds. That’s pure wind slop, not surf.
We start Friday the 11th with nothing, and that sets the tone. We go through Friday, Saturday, Sunday, Monday, Tuesday, and Wednesday – all blank. Thursday the 17th offers a moderate offshore breeze from the east at 12 mph, which would be beautiful if there were any waves, but there aren't. The pattern keeps going: Friday the 18th, Saturday the 19th, Sunday the 20th, Monday the 21st, Tuesday the 22nd, Wednesday the 23rd – it’s all the same story. Clean conditions, glassy mornings even, but a total lack of swell.
We finally see a little blip on Thursday the 24th morning with glassy conditions (slight air, 3 mph from the NE), and on Friday the 25th morning there’s a gentle offshore from the east at 9 mph with a tiny 0.7ft swell from the WNW at a 5-second period – too small and weak to do anything with. That’s as good as it gets, and it’s not good.
Honestly, there is no standout session in this entire forecast. The water temperature is about average for this time of year, but it doesn’t matter when there’s nothing to ride. It’s a tough run for Anna Maria Key. Combined energy values are all in the 0 to 2 range – laughably weak.
This kind of prolonged flat spell is more normal for the area in this season. All we can do is watch the charts and hope something changes. For now, leave the boards in the car.
Rusty.

Information about the Anna Maria Key Surf forecast
The above surf forecast table for Anna Maria Key provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Anna Maria Key can be found by selecting the local surf guide option on the grey menu. Our Anna Maria Key surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Anna Maria Key) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
