The Lowdown
Alright folks, Rusty here. Let me be real with you right off the bat—this forecast is a tough one. We're looking at a 16-day window for Anna Maria Key, and frankly, it's a long stretch of flat, poor conditions. The combined swell energy barely registers, topping out at a measly 2, which is about as weak as it gets. The good news is that water temps are sitting at 88°, which is a touch warmer than normal for this time of year, so if you're bored, it's at least a nice swim.
The first bit of surf is a whisper on Friday, September 4th. We've got a tiny 1ft swell from the southwest with a short, gutless 3-second period, and a cross-on southwesterly breeze at 9 mph. It's choppy, it's weak, and it's not worth paddling out for. The next few days are a total write-off—Saturday the 5th through Monday the 7th all show zero wave energy, mostly onshore or cross-on winds, and poor conditions. We're looking at a gap of several days with absolutely nothing to recommend.
Tuesday the 8th offers a clean morning with an offshore breeze, but no swell to go with it. Then in the afternoon, a tiny 1.0ft groundswell creeps in from the west-northwest with a 2-second period, but it's cross-onshore. The energy is a 1. It's basically a ripple. We see similar tiny pulses of 0.7ft to 1.0ft on Friday the 11th and Saturday the 12th, but the winds are either onshore or cross-on, ruining any chance of a clean wave. The combined energy never gets above 1.
The second week looks cleaner on the wind front, with several mornings showing offshore breezes, and the afternoons often clean or with cross-offshore winds. But the problem remains: there is no swell. From Sunday the 13th all the way through to Saturday the 19th, the wave energy is a flat zero. The winds will be glassy and clean, but there's nothing to ride. It's a long, dull run. For a beach break like Anna Maria Key, this blank run is a bit more normal for the area, but it doesn't make it any easier to swallow.
Don't bother getting the board wet. The setup here is more interesting for a flat day paddle than any kind of surfing. Keep an eye on the charts, but for now, there's just nothing in the water.
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.
