The Lowdown
Alright, let’s get into it. The long and short of it is, we’ve got a whole lot of nothing across the entire 16-day window. If you’re looking to paddle out, you’re going to be sitting on your couch for a while. This stretch is a write-off for surf, plain and simple.
Starting from Sunday, August 16 right through to Monday, September 1st, every single session is rated as poor. There’s just no energy in the water.
Let’s talk about the first bit. Sunday morning, August 16, is glassy with a light wind, but there’s no swell at all. The combined swell energy is a flat zero (0). Later that day, the wind swings cross-on and picks up to 12 mph, just chopping up an already empty ocean. Water temp is sitting at 87°F, which is about a touch warmer than normal for this time of year at Anna Maria Key.
Monday, August 17, and Tuesday, August 18, finally show a tiny pulse, but we’re talking 0.3m to 0.5m of weak, short-period slop with periods of 2 to 4 seconds. Combined energy is barely registering (1 to 5). The wind is onshore and gusty, up to 16 mph. It’s windswell junk, not worth the drive.
The rest of the month follows the same sad story. Wednesday the 19th through to the end of August gives us nothing but flat spells or tiny 0.3m to 1.3m dribble with 3 to 4-second periods. The combined energy never gets above 6. Winds are mostly onshore or cross-onshore, keeping any ripple chopped and messy.
There are a few glassy windows, like the morning of Sunday, August 23, and the morning of Thursday, August 27, but with no swell to speak of, it’s just a pretty piece of flat water. On Monday, August 25, we get a clean offshore breeze from the ESE at 6 mph, but again, flat.
Because the break is a beach/pier setup, and we’ve got onshore winds and tiny swell, this is honestly more of a kitesurfing setup than a paddle surfing one. For a paddle surfer, there’s nothing here worth chasing. It’s a rare blank run, but sometimes the Gulf just shuts down. Forecasts can always change, so keep an eye out, but for now, leave the boards in the garage.

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.
