The Lowdown
Alright, if you’re hanging out for some waves at Anna Maria Key, I gotta be straight with you—it’s looking pretty lean for the next couple of weeks. There’s nothing on offer that I’d call a standout, so we’re in a real quiet spell here.
Right now and for the foreseeable future, it’s a whole lot of nothing. We’ve got a big gap of almost no surfable energy. From Thursday the 13th right through until Friday the 28th of August, every single day is coming up with “poor surf conditions” and barely a ripple. The combined swell energy never climbs above a piddly 8 (weak energy), with most days sitting at zero energy. That’s rough.
Thursday the 13th morning kicks off with a tiny 0.3m (1ft) swell from the NW, but it’s only 3 seconds of period—just wind slop—and a cross-onshore breeze at 10 km/h (6 mph) messes it up. Afternoon gets worse with 20 km/h (12 mph) cross-onshore. Friday the 14th morning goes glassy but with only a pathetic 0.1m (0.3ft) NW swell and a period of 4 seconds. There’s literally nothing to ride.
We do get a tiny bump late in the run. On Friday the 28th of August, morning shows a 0.6m (2ft) swell from the west with a 3-second period, and the combined energy finally hits 8 (weak). Wind is light and onshore at 10 km/h (6 mph), so it’s not clean, but if you’re desperate, that’s the biggest bit of movement in the whole 16 days. Still, with that period you’re looking at bumpy, weak little closeouts—honestly more of a paddle than a surf.
Truth is, for an exposed beach/pier spot like Anna Maria Key, this sort of flat run isn’t unheard of. We need some proper NW groundswell to kick in, but the forecast just isn’t showing it. Keep an eye out though—forecasts can change. For now, unless you’re dying for a float, leave the board in the car.

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.
