Christmas in July In the Southern Hemisphere, seasons are in reverse to the Northern Hemisphere, with summer falling in December, January, and February, and with winter falling in June, July, and August. Therefore, in some southern hemisphere countries, such as Comoros, Madagascar, Bolivia, Angola, French Polynesia, Papua New Guinea, Paraguay, Samoa and South Africa, Christmas in July or Midwinter Christmas events are undertaken in order to have Christmas with a winter feel in common with the northern hemisphere.[14][15][16] These countries still celebrate Christmas on December 25, in their summer, like the northern hemisphere.
