The Lowdown
G’day, Rusty here. I’ve got to be straight with you – for Anna Maria Key, the next 16 days are a write-off. There’s nothing on offer that I’d even call a surf. We’re looking at a full blank run from now through to the 30th of August, with no decent swell, only tiny dribbles at best.
The first glimmer of any wave energy shows up around Monday the 17th of August morning, with a miserable 0.7 ft swell from the WNW at a short 3 seconds. Combined energy is a weak 1 – that’s barely a ripple. Conditions are choppy with a 9 mph cross-onshore wind. It goes downhill from there. Tuesday the 18th morning offers 1 ft at 4 seconds (energy 6) but it’s onshore and hopeless. Wednesday the 19th morning has 1 ft from the WNW at 5 seconds (energy 11), but again, onshore wind kills it. The rest of the week sees similar scraps: tiny heights, short periods, and unfriendly wind.
After the 21st of August, it gets even worse with days of flat, clean conditions but no swell whatsoever. A tiny 0.3 ft NW swell pops up on the 29th of August afternoon (energy 1) and another on the 30th of August morning (energy 1) with offshore wind, but it’s laughable. Don’t even bother.
For context, the water temperature is about average for the time of year here, so nothing unusual to report on that front. But the reality is simple – there are no good surf options in this entire 16-day window. This kind of flat spell isn’t unusual for the area, so don’t get your hopes up. I’d say keep an eye on the forecasts, because it tends not to stay this poor forever, but right now? Stay home.
Rusty.

A general guide to surfing at Anna Maria Key can be found by selecting the local surf guide option on the grey menu.

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.
