What is the Fall Equinox?
The fall equinox is a special event that starts autumn in the Northern Hemisphere. It happens when the Sun crosses the celestial equator. This creates a balance of light and darkness on our planet.
There are many ways to define when autumn starts. Scientists and meteorologists use different methods:

The Science Behind Seasonal Changes
Fall starts with a cool astronomical event. It shows how Earth and the Sun move together.
Earth tilts at 23.5 degrees. This tilt makes the seasons change. It affects how sunlight hits our planet, mainly during the autumnal equinox.
Why Seasons Change
Seasons don’t change because of how far Earth is from the Sun. It’s Earth’s tilt that matters. This tilt changes how sunlight spreads around the world.
- Earth’s axis remains tilted at approximately 23.5 degrees
- Different regions receive varying amounts of direct sunlight
- Northern and Southern Hemispheres experience opposite seasons
Effects of Fall on Daylight
When does fall start? The autumnal equinox, around September 22 or 23, marks the start. Daylight starts to get shorter in the Northern Hemisphere.
| Season | Daylight Hours | Sun’s Position |
|---|---|---|
| Fall Equinox | Approximately 12 hours | Directly above Equator |
| After Equinox | Decreasing daily | Shifting southward |
As Earth moves, the Northern Hemisphere gets shorter days. It gets longer nights until winter solstice.
Fall Weather Patterns
As autumn starts, the weather in the United States changes a lot. The fall equinox marks a big change in the air. It brings weather that is special to this season.
When autumn starts, the air changes in interesting ways. Many places see big changes in temperature during this time.
Average Temperatures Across Regions
Weather data shows interesting temperature trends in fall:
- Southeast regions: Temperatures stay warmer
- Pacific Northwest: Temperatures are 4-8 degrees above average
- Northeast: It’s unusually warm here
Weather Event Characteristics
Fall brings special weather events:
| Weather Event | Potential Impact |
|---|---|
| Severe Weather Outbreaks | Increased risk of damaging winds |
| Tropical Storm Activity | Potential hurricane developments |
| Cold Air Masses | Potential sudden temperature drops |
Weaker winds from the polar vortex lead to unpredictable weather. Cold air can move south quickly. The first big fall cooldown usually happens on the first full weekend of fall.
Climate scientists say Earth’s tilt of about 23.5 degrees causes these weather changes. It’s what makes seasons change.

The Beauty of Fall Foliage
As the fall equinox date comes, nature gets ready for a colorful show. Leaves change colors in a beautiful way. They turn red, orange, and yellow, making landscapes look amazing.
Leaf Colors and Changes
The science behind fall leaves is cool. When days get shorter and it gets colder, trees stop making chlorophyll. This lets hidden colors show, making leaves look stunning:
- Red leaves: Typically from maple trees
- Yellow leaves: Common in birch and poplar trees
- Orange leaves: Often found in oak and beech trees
Best Places to View Fall Leaves
Every place has its own special fall colors. Here are some great spots for leaf-peeping:
- Vermont’s Green Mountains
- New Hampshire’s White Mountains
- North Carolina’s Great Smoky Mountains
- Colorado’s Rocky Mountain National Park
Peak fall colors happen from late September to late October. Places like Montana see colors early, in the first week of September. Southern places like Texas see peak colors in late October to early November.
Pro tip: Check local foliage forecasts for the best leaf-viewing trip. Sunny days and cool nights make colors pop, creating a magical scene.
