Solve: Southern Hemisphere Seasons

Created By: Geoffrey Challen

/ Version: 2026.2.0

In the Southern Hemisphere, the seasons are opposite to the Northern Hemisphere! Create a function called southernSeason that accepts an Int representing a month (1 for January through 12 for December) and returns a String with the name of the season as experienced in Sydney, Australia.

The Southern Hemisphere seasons are:

• Summer: December (12), January (1), February (2)
• Autumn: March (3), April (4), May (5)
• Winter: June (6), July (7), August (8)
• Spring: September (9), October (10), November (11)

So while people in New York are bundling up for winter in January, Sydneysiders are enjoying a beach day in the middle of summer!

You can assume the input will always be a valid month number between 1 and 12.
