E. Elert. flu in winter. Flu season is in full swing across the U.S. this week, and it's right on time. Actually, it would have been on time if it showed up in November, too, or even in March--unlike the actual seasons, the timing of flu season is a little hard to predict. Except for one thing: it always happens in winter.
Astronomical dates for the start of seasons for the southern hemisphere are: around the 21st of June for Winter, around the 21st of September for Spring, around the 21st of December for Summer and around the 21st of March for Autumn (fall).
