Ruse of the "even out" effect

Yes, we've had a wet winter dry season ...

But the summer wet season that preceded it was dry.
Here's another confusing chart.  But if you spend a minute with it, it may start to make sense.  From top to bottom, it shows wet season, dry season and water year (i.e. as measured  for the 12-month span from May - April) for south Florida.  The bars show deviation from the long-term normal.  Thus, the larger the bare, the larger the deviation from the norm.  Blue bars are wetter than normal and red bars are drier than normal.

Add them together and you get a normal rain year amount,

Even if this water year has been anything but that (i.e. normal).


More proof that numbers don't always tell the full truth.
