Understanding the Difference Between Meteorological Fall and the Official Start of Fall

PINE BLUFF, Ark. – As the long, hot days of summer in South Arkansas begin to wind down, many folks start to yearn for the cooler temperatures, vibrant foliage, and cozy atmosphere that fall brings. But did you know that there are actually two different dates when fall can officially begin? If you’ve ever wondered why the weather seems to shift to fall before the calendar marks the first day of autumn, you’re not alone. The answer lies in the difference between meteorological fall and the official start of fall, also known as the autumnal equinox.

Meteorological Fall: A Practical Approach

Meteorological fall begins on September 1st, and it’s all about simplicity and consistency. Meteorologists and climatologists divide the year into four distinct seasons: winter, spring, summer, and fall. Each season is exactly three months long, making weather forecasting and climate tracking more straightforward. Fall, by this definition, runs from September 1st to November 30th.

This method of marking the seasons makes sense when you consider the climate patterns in South Arkansas. By early September, many residents notice a slight, even if ever-so-slight it is, shift in the weather—cooler mornings, shorter days, and even the occasional drop in humidity. While temperatures may still climb during the day, the change is noticeable, signaling that summer’s grip is loosening.

The Autumnal Equinox: The Official Start

The official start of fall, known as the autumnal equinox, typically occurs around September 22nd or 23rd. This date is based on astronomy rather than weather patterns. On the equinox, day and night are roughly equal in length, and the sun crosses the celestial equator. It’s a moment that has been celebrated in various cultures for centuries, symbolizing balance and transition.

In South Arkansas, the equinox often brings with it more dramatic shifts in weather. By late September, the days have noticeably shortened, and cooler temperatures become more common, especially in the evenings. For many, this is the true beginning of fall, marked by the first hints of changing leaves and the scent of woodsmoke in the air.

Why the Difference Matters

While the distinction between meteorological and astronomical fall might seem trivial, it has practical implications, especially in a region like South Arkansas where agriculture plays a significant role. Farmers, for example, rely on meteorological seasons to plan planting and harvesting, as these dates align more closely with temperature changes and weather patterns.

For the rest of us, understanding the difference can simply make us more attuned to the natural world around us. Whether you’re counting down the days to pumpkin spice lattes or eagerly awaiting hunting season, recognizing the subtle shifts in weather that signal the arrival of fall can enhance your appreciation of this beautiful time of year.

A South Arkansas Fall

In South Arkansas, fall is more than just a date on the calendar—it’s a season rich with traditions and memories. From the excitement of Friday night football games under the lights to the warmth of family gatherings, fall is a time to slow down and savor the beauty of our natural surroundings.

So, whether you’re a stickler for the official equinox or you start celebrating fall as soon as September arrives, there’s no wrong way to enjoy the season. Just make sure to take a moment to step outside, breathe in the crisp air(hopefully coming soon), and enjoy the special charm that fall brings to South Arkansas.

As the old saying goes, “Autumn carries more gold in its pocket than all the other seasons,” and here in South Arkansas, that gold is found in the cool breezes, the golden sunsets, and the warmth of community that makes this time of year so special.
