E. Elert. flu in winter. Flu season is in full swing across the U.S. this week, and it's right on time.

Except for one thing: it always happens in winter.
The meteorological seasons in the Southern Hemisphere are also opposite to those in the Northern Hemisphere: 1  Fall (autumn) - starts March 1 and ends May 31; 2  Winter - starts June 1 and ends August 31; 3  Spring - starts September 1 and ends November 30; and, 4  Summer - starts December 1 and ends February 28 (February 29 in a Leap Year).
