What Are the Four Seasons
The four seasons are spring, summer, autumn, and winter. They repeat yearly in most temperate regions and are driven by Earth's axial tilt and orbit around the Sun.
Order and Timing of the Seasons
In the Northern Hemisphere, spring begins around March 20, summer around June 21, autumn around September 22, and winter around December 21. In the Southern Hemisphere, the order is reversed, with summer starting in December and winter in June. Learn more about seasonal timing from the National Weather Service at https://www.weather.gov/
Key Characteristics of Each Season
Spring brings warming temperatures, longer days, and plant growth. Summer features the warmest weather and longest daylight. Autumn brings cooling temperatures, changing leaves, and harvest activity. Winter brings the coldest temperatures, shorter days, and, in many regions, snow and frost.
