Average temperatures were near or slightly above normal for April across the entire state. Departures from normal ranged from normal at Key West to 3.5˚F at Tallahassee. While March 2012 was extremely warm for much of the state, average temperatures for April saw a return to normal, partly due to the weakening La NiƱa. There were numerous records broken during April, both maximum and minimum temperatures.
