The Lowdown
Alright, Rusty here again. Let’s be honest: the outlook for Anna Maria Key over the next 16 days is a big fat zero for surf. The energy is just dead. The biggest combined swell energy we see is a weak (8), and most of the time it’s nothing. We are in a serious lull.
Right from the start, there's a huge gap. From now until the end of August 28th, there’s nothing that’s going to get a surfer out of bed. The water is warm at 86°F, which is normal for the season, but that’s the only good news.
On Thursday, August 13th, there’s a tiny 1ft swell from the NW, but it’s choppy with a cross-onshore wind. It’s useless. Friday the 14th morning is glassy flat, with a swell of just 0.3ft.
We see a couple afternoons, like Monday the 17th and Thursday the 20th, where the swell bumps to 2ft from the WNW and the energy ticks up to (8), but the wind goes onshore and ruins it. The period is a short 3 seconds, so there’s no grunt.
Look, with a beach break and no consistent swell, this is a normal dry spell for the area. Keep your gear handy, but don’t hold your breath.
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.
