The Lowdown
Alright folks, Rusty here. I've scanned the charts for the Anna Maria Key zone for the next couple of weeks, and to be straight with you, it's looking pretty grim. There's a whole heap of flat, windy days ahead.
The closest thing to any action is on Tuesday the 18th. There's a tiny bit of swell, maybe 2 to 2 ft, coming from the Northwest. But with a period of just 4 seconds, it's pure messy wind chop. The combined energy is a weak 10, and it's going to be cross-onshore and choppy with the wind kicking up to 16 mph. This is one of those days where the wind is way more powerful than the waves, so if you're into kite-surfing, it'll be more interesting than paddling. The water temp is about average for now.
And that's basically it. That's the only window. From now until Monday the 24th, it's a long stretch of flatness. You get a few clean, glassy mornings, like Thursday the 20th with a clean offshore breeze, but there's no swell at all. The little bumps of wind swell on the 23rd and beyond are pathetic – 0.6 to 1 ft – and usually blown out.
There's no standout session. Nothing to mark on the calendar. If you're totally itching for a paddle on the 18th and you have a big foil board, maybe, just maybe. But that's a massive maybe. It's a real quiet spell. Forecasts can always change, but for now, the outlook is poor.
Rusty.

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.
