The Lowdown
Alright folks, Rusty here. Let's break down what's on offer for Anna Maria Key.
To be straight with you, it's a dead spell. We’ve got a real gap here. Starting Monday afternoon, August 17th, all the way through the 19th, you’ll see tiny waves – 1 to 2 feet – but they’re from the west with periods of only 2 to 4 seconds. That’s just wind slop. The wind is blowin' onshore or side-onshore at 12 to 15 mph, so it’s choppy. Wave energy is pitiful (single digits). Not worth your time.
From the 20th through the 22nd, it gets even smaller: 0.5 to 1 foot, with even shorter periods around 3 to 5 seconds. Energy is still weak (1 to 9). Wind is still messy. It’s not surfable.
Then from Sunday, August 23rd, right through to Monday, August 31st, it goes completely flat. No swell at all. Energy is zero. We get a few glassy mornings – like the 23rd, 25th, and 26th – with no wind, perfect for a mirror-flat ocean, but there’s nothing to ride. Huge empty stretch.
Over the whole 16-day window, there’s nothin’ that stands out. Anna Maria Key is a beach/pier spot that faces northwest, but this forecast gives it zero. Crowds? Not a problem, ‘cause nobody’s paddlin’ out.
This spot is usually “fairly consistent,” so a blank run like this feels rough. It won’t stay this way forever. Forecasts shift.
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.
