If Florida had a single representative rain gage ...
Below is a chart of what it would read for the past year.
The problem is that the panhandle and the peninsula have distinctly different regimes thus making a state-wide average not representative of either one.
The primary difference is the winter.
On the panhandle regular doses of continental fronts bring waters to an annual peak but, under normal conditions, tend to stall to the south.
That leaves the peninsula – and more so the farther you go south – with a dry winter and spring.
Fortunately for us, Florida has more than one rain gage.
But come to think of it, having just one gage would simplify the math.
