Summer Solstice 2026: Exact Time It Will Occur in Mexico on June 21

The summer solstice, a significant astronomical event, will officially begin the summer season in the Northern Hemisphere on Sunday, June 21. This day marks the longest period of daylight and the shortest night of the year, a phenomenon celebrated by millions worldwide.

According to the Spanish National Geographic Institute, the solstice will occur precisely at 10:24 AM. For Mexico, this translates to 2:24 AM Central Time. In Mexico City, residents can expect sunrise around 5:59 AM and sunset at approximately 7:18 PM, providing over 12 hours of sunlight.

The Earth's axial tilt of approximately 23.5 degrees relative to its orbital plane around the Sun causes this event. During the summer solstice in the Northern Hemisphere, this tilt positions the region to receive the maximum amount of direct solar radiation. Conversely, the winter solstice occurs when the Northern Hemisphere is tilted farthest away from the Sun, resulting in the shortest day of the year.
