The June solstice brings the longest day for the Northern Hemisphere, but the earliest sunrises occur before it.
For the Northern Hemisphere, the earliest sunrises can happen as early as late May, with much of the United States experiencing them in the week leading up to the summer solstice.
In the Southern Hemisphere, the earliest sunsets occur about a week before the June solstice.
The June solstice falls at 2:42 UTC on June 21 for the Northern Hemisphere and at corresponding times for the Southern Hemisphere.
At 40 degrees north latitude, the earliest sunrise of the year is around June 14, not exactly on the solstice date.
The inclination of Earth's rotational axis causes the earliest sunrises before the summer solstice and earliest sunsets before the winter solstice.
In June, the day is slightly longer than 24 hours, leading to later sunrise and sunset times around the solstice.
Northern latitudes may experience the earliest sunrise closer to the solstice, while southern latitudes see it earlier.
The Earth's elliptical orbit affects the timing of earliest sunrises and sunsets relative to the solstices.
Early risers in the Northern Hemisphere are currently witnessing their earliest sunrises of the year.
