This calendar chart shows historic monthly rainfall, from 1960 to present, for all of south Florida. Can you find August of 2012? It's the big blue dot at the bottom of the chart. There aren't many of those big blue dots, just a good dozen over the past five decades. Even rarer are the black dots (when over 12.5 inches of rain fell in any given month). The last one of those was June 2005.
