In Northern-hemisphere locations, spring occurs during the months of March, April and May. (Summer is June, July, August; autumn is September, October, November; winter is December, January, February.) Southern-hemisphere locations will have opposing seasons with spring in September, October and November.

The first swallow to arrive or the flowering of lilac may be the indicator of spring. It therefore varies according to the climate and according to the specific weather of a particular year.
