The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window for Anna Maria Island is a tough one to call. We’re looking at a real flat spell, so don’t be in a rush to wax up. There’s a long gap of nothing worthwhile at the start, and honestly, the whole outlook is a struggle.
The first real chance of anything on offer doesn’t kick in until the morning of Thursday, August 20th. All that time before is just small, weak windswell and onshore junk. From the 10th through the 19th, it’s all zero scores and "poor surf conditions" – a grind of waist-high slop at best. You’ll be waiting nearly a week and a half for a pulse.
So, Thursday, August 20th. The pick of the bunch, but it’s still a marginal one. In the morning we’ve got a weak 2 ft swell from the west, with a period of 6 seconds. Not much energy (22 combined energy), but the wind is a light cross-shore from the NE, keeping things tidy. The afternoon session on the 20th is the true standout on the whole forecast. The swell drops to 2 ft, still from the west with a 6-second period, but the combined energy jumps to 51 – still moderate, but a bit more push. The real kicker is the wind: clean, cross-offshore from the east at just 6 mph. This is the time to go. It’s small, but it’s the cleanest it’ll be. Anna Maria is exposed to the WSW, so that west swell direction is a decent match. The water is sitting at a warm 86°, which is about normal for this time of year.
After that, it’s mostly small and clean but still tiny. The morning of Friday, August 21st, has a cross-offshore breeze and a 1 ft west swell, but the energy is barely there (7 combined). Saturday, August 22nd, has a strong cross-offshore wind from the ENE at 19 mph, but the swell is only 1 ft from the WSW. It’s clean, but you’ll be fighting the wind for a dribble.
The long-range stuff from the 23rd onwards is just as poor. Small, clean, but no real swell. The 24th has a risk of thunderstorms and a strong offshore wind from the SE at 22 mph, but the swell is a pathetic 0.7 ft. It’s not worth the paddle.
Bottom line: if you’re desperate for a surf, make the call for Thursday afternoon, August 20th. It’s the only time the small, clean conditions line up. Otherwise, leave the board in the car and enjoy the beach.
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.
