The Lowdown
Alright folks, Rusty here. Let's take a long, hard look at what Anna Maria Island has got cooking for us over the next couple of weeks. I gotta be straight with you – it's a tough stretch. We're looking at a real dry spell for surfable waves.
The main issue is that we just don't have any significant swell on the horizon. The dominant wind is coming from the west and northwest, which is fine for the offshore angle on paper, but it's blowing over a flat ocean. The small scraps of energy we see are tiny, short-period windswell, barely registering any energy at all. For the first few days, from Thursday the 20th through the weekend, we're looking at that tiny 0.7ft to 1ft of pure slop. The overall energy from the swells is basically a '4' – that's about as weak as it gets. The water temp is a toasty 88°, which is a touch warmer than normal for this time of year, so at least you won't be cold if you're just floating around.
The forecast shows a gap of absolutely nothing from Monday the 24th all the way through to Friday the 28th. There's just no swell at all. The winds are light and variable, sometimes offshore, even glassy, but there's nothing for them to blow on. It's a classic case of "good conditions, no waves."
Come Friday the 28th afternoon, we get a tiny pulse of swell from the WNW, but it's only 0.7ft with a period of 5 seconds. That's just wind chop. The wind is howling onshore at 16 mph from the NW, so it's going to be a mess. The energy is still only a '2'. This pattern of tiny, weak swell with onshore winds or just flat spells continues right through to the end of the forecast on September 4th.
There is one tiny moment of hope. On Saturday the 29th, the morning is glassy with a light SE wind, and there's a hint of 0.7ft WNW swell. The combined energy is a weak '2'. It's still tiny, but all it needs is one little pulse to make those puddles fun. If you're desperate, that Saturday morning glass-off is the single best chance you'll see.
Honestly, for the whole 16-day window, there's nothing here that gets a surfer's heart pumping. It's a flat spell. If the wind is that NW onshore and the swell is that small, it's more of a kiteboarding setup for the adventurous types than a paddle surf situation. The forecast can always change, but for now, don't plan your life around it.
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.
