That's TRUE.
For example:
-- When it's Winter in Canada, the USA, and France, it's Summer in Australia, Paraguay, and Namibia. (This is the end of December, all of January and February, and most of March.)
-- When it's Winter in Tasmania, South Africa, and Botswana, it's Summer in Germany, Israel, and Mexico. (This is the end of June, all of July and August, and most of September.)
-- The Spring and Fall are opposite too.
