The Lowdown
Alright folks, Rusty here. Let me level with you straight up. We’re looking at a pretty bleak stretch ahead for Anna Maria Island. The entire 16-day window is a write-off for any decent surf. There’s just nothing on the table.
Right from the start, the first recommendation period is essentially a no-go. You’ve got tiny, weak swell and poor conditions. The water is sitting at a warm 88°, which is a touch warmer than normal for this time of year, so it’s nice for a swim, but not for surfing. The combined energy of all swells directed here is a measly 7 (weak energy), coming from the WNW at a paltry 2 ft with a period of only 4 seconds – that’s pure wind chop, no grunt at all.
We roll through the following days, and it’s the same story. The swell barely flickers, often dropping to zero. The wind is mostly cross-onshore or cross-shore, keeping things choppy or messy. There’s a brief moment on the morning of the 24th of August where the wind goes light and clean, but with waves only 0.7 ft showing, you’d be hard-pressed to even get wet. The combined energy values are all in the single digits – weak, weak, weak.
Then from the 25th of August all the way through to the 3rd of September, the swell completely flatlines. It’s zero swell, zero energy across the board. The wind does go glassy or clean on a few mornings, like the 26th of August, the 1st of September, and the 3rd of September, but it doesn’t matter with no waves to push.
Look, this spot is inconsistent at the best of times, and this run is a classic example of a blank period. If you’ve got a kite, you might find some fun on those breezy afternoons, but for a paddle surfer, there’s simply nothing to get excited about over the next two weeks. Keep the board in the car and hope the forecasts change.
Rusty.

Information about the Anna Maria Island Surf forecast
The above surf forecast table for Anna Maria Island 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 Island can be found by selecting the local surf guide option on the grey menu. Our Anna Maria Island 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 Island) 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 Island 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.
