Is autumn the last season? The short answer is no. Autumn is the third season in the traditional four-season calendar, followed by winter. Each season has distinct characteristics and plays an essential role in the annual cycle of weather and nature.
What Are the Four Seasons?
The year is divided into four seasons: spring, summer, autumn, and winter. Each season lasts about three months and is marked by changes in weather, daylight, and ecological events.
- Spring: Begins in March (Northern Hemisphere) or September (Southern Hemisphere). Characterized by warming temperatures and blooming plants.
- Summer: Starts in June (Northern Hemisphere) or December (Southern Hemisphere). Known for hot weather and long days.
- Autumn: Commences in September (Northern Hemisphere) or March (Southern Hemisphere). Notable for cooler temperatures and falling leaves.
- Winter: Begins in December (Northern Hemisphere) or June (Southern Hemisphere). Defined by cold weather and shorter days.
Why Do Seasons Change?
Seasons change due to the Earth’s tilt and orbit around the Sun. The planet’s axial tilt of approximately 23.5 degrees causes different parts of Earth to receive varying amounts of sunlight throughout the year.
- Equinoxes: Occur in spring and autumn when day and night are approximately equal. They mark the transition between the warm and cold seasons.
- Solstices: Occur in summer and winter, marking the longest and shortest days of the year, respectively.
What Happens During Autumn?
Autumn, also known as fall, is a transitional season where temperatures gradually drop. Here are some key features:
- Weather Changes: Days become cooler, and nights grow longer.
- Leaf Color: Deciduous trees change color as chlorophyll breaks down, revealing vibrant reds, oranges, and yellows.
- Harvest Time: Many crops, such as apples and pumpkins, are harvested.
- Wildlife Activity: Animals prepare for winter by migrating or storing food.
How Does Autumn Affect Daily Life?
Autumn’s arrival influences various aspects of daily life and culture:
- Fashion: People switch to warmer clothing, such as sweaters and jackets.
- Festivals and Holidays: Celebrations like Halloween and Thanksgiving are popular in autumn.
- Outdoor Activities: Hiking, apple picking, and leaf-peeping are common autumn activities.
How Does Autumn Compare to Other Seasons?
Here is a comparison of how autumn compares to the other three seasons:
| Feature | Spring | Summer | Autumn | Winter |
|---|---|---|---|---|
| Temperature | Mild | Hot | Cool | Cold |
| Daylight | Increasing | Longest | Decreasing | Shortest |
| Key Events | Blooming | Vacation | Harvest | Snowfall |
| Wildlife | Awakening | Active | Preparing | Hibernating |

Autumn is characterized by cooler temperatures, shorter days, and longer nights. Trees shed their leaves, and many animals prepare for winter by migrating or storing food. It’s also a time for harvest and various cultural festivals.
Why do leaves change color in autumn?
Leaves change color in autumn due to the breakdown of chlorophyll, the green pigment responsible for photosynthesis. As chlorophyll depletes, other pigments like carotenoids and anthocyanins become visible, resulting in vibrant autumn colors.
