The Lowdown
Alright folks, Rusty here. Let’s take a tough look at what’s happening for Anna Maria Key over the next sixteen days. Gotta be honest – this is a brutal stretch for surfing.
First off, the water is warm at 88°, about 3° warmer than average for this time of year—nice for swimming, not for waves.
The forecast starts Thursday the 20th of August. Thursday morning offers a tiny 2 ft swell from the WNW with a period of just 5 seconds, blowing in a light NNW cross-onshore. The combined energy of all swells is weak (20). Thursday afternoon stays 2 ft but the period drops to a lousy 3 seconds and wind picks up, making it choppy. Total poor surf.
From Friday the 21st through Monday the 24th of August, the swell drops to near nothing—under 1 ft with periods of 2 to 5 seconds. Winds are mostly onshore or light cross-off, but with no energy, there’s nothing to ride.
Tuesday the 25th and Wednesday the 26th of August go absolutely flat. Zero energy.
Thursday the 27th of August morning is glassy with zero swell. Flat calm, no waves.
Friday the 28th through Sunday the 30th of August is flat to barely ankle-high with 0.6 ft dribbles. Light cross-onshore or onshore winds. No good.
From Tuesday the 1st of September through Friday the 4th, the biggest pulse is a 1 ft swell from the WNW on Thursday the 3rd with a 5-second period and weak energy (5), but still light cross-onshore. Not worth it.
What’s the standout? I’ve got nothing for you. Every single entry says “poor surf conditions” with a zero out of ten rating. No recommendations across the whole sixteen days. This is a full blank run. For Anna Maria Key, a beach/pier setup, dead spells happen, but this one is long and solid. No swell, poor wind, no drive to paddle out.
If you’re itching for surf, you’re out of luck. Forecasts can change, but right now, this is a total bust.

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.
