Marco Island's high season is from mid-December through March, 
however the weather is usually gorgeous from late October through the 
end of April.  Being on the water offers breezes year round.

Although temperatures hover near 90 degrees in the summer months, the 
afternoon showers provide wonderful relief for the 
evenings.  Plan on napping or curling up with a good book for a 
couple of hours each afternoon in the summer.
