The Lowdown

Hey folks, Rusty here. I’ve been staring at the charts for Anna Maria Key and, well, it’s a tough one. We’re looking at a 16-day window and honestly, the surf is pretty much flatlined the whole way through. There’s not a single session I’d call a standout, and for most of the run, you’ll be hard-pressed to find a wave worth paddling for.

The first hint of anything comes on Tuesday, August 18th, with a tiny 1 ft to 2 ft swell out of the WNW. The combined energy is a measly 4 to 6 (weak), and it’s blown out by a 12 mph onshore wind. The period is a short, weak 3 seconds. That’s a no-go. The water’s sitting at 88°, which is a touch warmer than normal, but that won’t help the waves.

We go through the rest of the week with the same story: Wednesday, August 19th, the swell stays at 2 ft, period climbs to 4–5 seconds, and the energy is still weak (10–11). By Thursday, August 20th, it’s even smaller, 1 ft, with a period of 4 seconds. The wind is light, but it’s all onshore or cross-onshore, keeping the surf poor. The combined energy drops to 6 or 7. This pattern just repeats. Friday, August 21st, sees 1.0 ft at 5 seconds. Saturday, August 22nd, is a joke with 0.7 ft to 1.0 ft, and the wind turns cross-onshore, making it choppy. The energy is down to 1 to 3.

The second week offers no hope. From Sunday, August 23rd, through to Wednesday, September 2nd, the swell is either below 1 ft or completely flat (dashes). The wind is often onshore, cross-onshore, or non-existent. There are a few moments of glassy or light offshore wind on the 30th, 31st, and 1st, but with no swell to work with, it’s just a pretty, flat ocean. The combined energy is either 0 or a single digit. There’s a stretch from around August 26th to September 2nd where there are several days back-to-back with no surf at all.

At this point, the setup at Anna Maria Key is a beach and pier zone. With the strong onshore winds and minimal, weak swell, it’s really more of a kiteboarding situation than a surfing one. For us paddle surfers, this is a blank run. It’s a quiet spell, but it happens. The forecasts can change, but right now, there’s just nothing to get excited about.

Rusty.

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.
