The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next 16 days are looking pretty flat for Anna Maria Key. There’s a long dry spell ahead, so don’t get your hopes up.
We’re looking at a solid stretch from now right through the end of the month with very little to get excited about. The combined energy from any swell is barely registering, mostly in the weak single digits (0 to 8 range), so you’re not going to find any push. The water temp is sitting about average for this time of year, so no surprises there.
For the first week, from Sunday the 16th right through to the following Saturday the 22nd, it’s all tiny, weak, and choppy. We’re talking ankle-biters between 0.7 ft and 2 ft, mostly from the WNW or W, with periods so short they’re practically wind chop (2 to 5 seconds). The wind is either onshore or cross-onshore most of the time, keeping the surface messy. It’s honestly more of a day for a cold drink on the beach than a surf.
There’s a tiny flicker of hope on the morning of Sunday the 23rd. A little 0.7 ft W swell shows up with a light NNE cross-offshore breeze, which is about as clean as it gets around here. But it’s barely a ripple, and the energy is just 1, so it's not even really worth paddling out for. Right after that, the wind swings back onshore and ruins the afternoon.
The second week doesn’t get any better. From Monday the 24th through to Monday the 31st, we’ve got a massive 7-day gap with absolutely no surf to recommend. The data shows “poor surf conditions” for every single session, with many days showing no swell at all. Even the glassy conditions on the morning of the 31st won’t help because there’s nothing to break.
Bottom line: leave the boards in the car. The setup here isn’t delivering anything for the next two weeks, and with the wind patterns we’re seeing, it’s a solid blank run. Forecasts can change, but right now, this is a hard pass.
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.
