The Lowdown
Alright folks, Rusty here. Let’s be straight with you about Anna Maria Key. The outlook for the next 16 days is a tough one. We’re looking at a long stretch of flat, poor conditions, so don’t get your hopes up for any proper rides.
The water’s running warm at about 88°, which is a touch warmer than normal for this time of year. Nice for a swim, but the surf just isn’t cooperating.
The forecast kicks off with nothing. Saturday the 5th and Sunday the 6th are total write-offs – clear skies but cross-onshore winds and a combined energy of zero (0). There’s no swell to speak of. Monday the 7th teases us with a tiny 0.7 ft to 1.0 ft windswell coming from the WNW and W, with a short period of just 2-3 seconds. The energy is barely a whisper (1), and the wind is onshore, making it a choppy mess. Not worth paddling out for.
Tuesday the 8th offers a glimpse of something clean. The morning has a light offshore breeze from the east at 3 mph, smoothing the surface right out. But the swell is still pathetic – 0.3 ft from the NW with a 4-second period and energy of just 1. It’s glassy, but there’s nothing to ride. That clean window is the only thing going for it, and it’s just not enough.
From Wednesday the 9th right through to the 16th, we’re looking at a big gap. Day after day of zeros and “poor surf conditions.” The wind switches around, but there’s simply no swell energy. The combined energy reads 0 for almost every session. It’s a dead run.
Then, on Thursday the 17th of September, we see a tiny bump. A 1 ft to 2 ft swell from the SW with a period of 3 seconds. The energy finally climbs to a 6 on the Thursday afternoon. The wind is light cross-onshore, so it’s not clean, but it’s the biggest surf we’ve seen. Friday the 18th morning offers a gentle offshore breeze from the ESE at 9 mph, cleaning up a 1.0 ft swell from the WSW. The energy is still low at 4. It’s the best of a bad bunch, but it’s tiny and weak.
Overall, there’s no standout day here. The best chance for a paddle is the morning of Friday the 18th when the wind is offshore and the waves are at least clean. But honestly, with such small swell and weak energy, don’t expect much. This is a blank run for Anna Maria Key. When it’s this flat, it’s a better bet for a beach day than a surf session.
Rusty.

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.

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.
