Event details
Start of Astronomical Summer - 4:25 AM
The summer solstice marks the astronomical start of summer in the Northern Hemisphere and occurs when Earth's axial tilt positions the North Pole at its maximum inclination toward the Sun. This results in the Sun appearing directly overhead at the Tropic of Cancer (23.5°N latitude), delivering the year's longest period of daylight and shortest night.
For North Georgia (including areas like Nelson and nearby Dacula, around 34°N latitude), the summer solstice in 2026 falls on Sunday, June 21 (local time; the exact moment is around 4:24 a.m. EDT, or 08:24 UTC).
Key effects at your location:
-
Longest day of the year: Expect approximately 14 hours and 25–30 minutes of daylight, depending on the exact spot. For reference:
- In nearby Atlanta (similar latitude), daylight on/around the solstice typically reaches about 14 hours and 25–29 minutes.
- North Georgia spots (slightly farther north than Atlanta) get very close to this, often around 14 hours 27–30 minutes.
- Sunrise and sunset: The Sun rises early (typically ~6:25–6:30 a.m. EDT) and sets late (~8:50–8:55 p.m. EDT), with the Sun reaching its highest noon position in the sky for the year (its maximum altitude ~79–80° above the horizon).
- Why the variation? Your latitude (~34°N) is well north of the equator but south of higher latitudes (e.g., 40–50°N), so daylight extremes are noticeable but not as dramatic as in places farther north (like New England or the Midwest, where it can exceed 15 hours).
This event signals peak solar energy input, contributing to warmer weather, longer evenings for outdoor activities, and the height of summer in the region. After the solstice, days gradually shorten as we head toward autumn. Enjoy the extra light!
