Start of Astronomical Fall - 8:06 PM
The fall equinox (also called the autumnal equinox) marks the astronomical start of autumn in the Northern Hemisphere. It occurs when Earth's axial tilt positions the Sun directly over the equator, resulting in nearly equal day and night lengths globally (though not perfectly exact—due to atmospheric refraction and the Sun's apparent size, daylight is typically a few minutes longer than 12 hours at mid-latitudes).
For North Georgia (including Nelson and nearby areas around 34°N latitude), the fall equinox in 2026 falls on Tuesday, September 22, with the exact moment at 8:05 p.m. EDT (corresponding to 00:05 UTC on September 23).
Key effects at your location:
Nearly equal day and night: Expect about 12 hours of daylight, often slightly more (around 12 hours and 4–10 minutes due to refraction making sunrise seem earlier and sunset later). For reference, in nearby Atlanta (similar latitude):
On or around September 22, sunrise is typically ~7:20–7:25 a.m. EDT, sunset ~7:25–7:30 p.m. EDT, yielding roughly 12 hours 5–10 minutes of daylight.
North Georgia spots see very comparable values, with daylight dipping just below the peak summer lengths and beginning its steady decline.
Sun position: The Sun rises due east and sets due west (azimuth ~90° and ~270°), reaching its highest noon position around 55–60° above the horizon (symmetric to the spring equinox but heading southward now).
Why it matters here: At ~34°N, the change feels clear—days have been shortening since the June solstice (losing ~1–2 minutes per day around equinox time). This signals cooler trends ahead, the peak of fall foliage season (vibrant maples, oaks, and hickories in the North Georgia mountains!), reduced humidity after summer, and the transition toward shorter, crisper days.
After the equinox, daylight continues to decrease until the December solstice, bringing the shortest day of the year. It's a perfect time for hikes in the Appalachians, pumpkin patches, and enjoying those golden-hour evenings before winter sets in. Happy fall—welcome the cooler vibes!
