Spring is the season between winter and summer. The Northern Hemisphere, which consists of the northern half of the earth, has spring weather during late March, April, May, and early June. In the Southern Hemisphere, spring weather begins about September and ends by early December.

Spring weather begins throughout much of North America with the melting of winter snow. In the polar regions, spring weather begins later and does not last a long as it does in the middle parts of the Northern Hemisphere. Tropical regions do not have great seasonal changes.

The number of daylight hours increases during spring, and most spring days have higher temperatures than winter days. Nature awakens in spring, when flowers bloom and hibernating animals leave their winter sleeping places. In many countries, the people have festivals celebrating spring.
