I'm not completely certain, but I think when it is summer in either the northern or Southern Hemisphere; it is the winter in the other and vice versa.
winter
Asia as well as the U.S. are in the northern hemisphere. What season we are having depends on whether you live in the northern or southern hemisphere, not eastern or western. Therefore, the U.S. and Asia always have the same season at the same time while Australia, South America, etc. have the opposite.
Spring
The Northern and Southern Hemisphere
It is Winter in the northern hemisphere.
it is summer in the northern hemisphere and winter in the Southern Hemisphere.
When it is summer in the southern hemisphere, it is winter in the northern hemisphere.
it depends on the hemisphere and what season. example: Northern hemisphere-(summer in the Southern) winter cold, Southern hemisphere-(winter in the Northern) summer hot
The season is spring in the northern hemisphere and Autumn in the southern hemisphere.
Spring
It is found in the northern hemisphere.
