What the newspapers won't tell you

South Florida doesn’t have four seasons, but rather two:

The summer wet season, which runs from May through October, and the winter dry season comprises the other half, from November through April.

Rainfall totals for the wet and dry season (to date) are mapped above.

Or, alternatively, if you add those together you get the full rainfall year …

As mapped below.

One of the common mistakes you see in the metropolitan newspapers is the reporting of annual rainfall by the calendar year, from January to December.

Swamp hydrologists, this one in particular, prefer charting up annual rainfalls from May to April instead. That way the wet season and dry season stacked on top of each other on the same bar.


The bar chart below does just that:

Wet season months are color coded blue and dry season yellow 

As you can see, this dry season
has some catching up to do.
