Although warm temperatures were registered earlier than expected in New York City, summer doesn’t officially begin until Sunday.
His arrival is scheduled for the annual summer solstice, which will occur at 11:32 pm on June 20.
The summer solstice, which also falls on Father’s Day this year, marks the time when the sun reaches the Tropic of Cancer, its highest point. It is also the longest day of the year in the Northern Hemisphere.
On Sunday, the sun will rise at 5:24 a.m. in New York and set at 8:30 p.m., which means we’ll see a full 15 hours of daylight.
The word “solstice” comes from the Latin words sol – the astro – and stitium, which means “standing”, according to The Old Farmer’s Almanac. At the summer solstice, the sun’s path stops moving north each day and appears to “stay still” in the sky before changing course and going back in the opposite direction.
While June 21 is generally recognized as the first day of summer, no authorized body has determined when the seasons begin. For example, Earthsky.org notes that in meteorology, summer actually begins on June 1.
Here is some data collected by The Old Farmer’s Almanac:
1. The sun sets more slowly on the summer solstice. This is related to the angle of the setting sun. The further the sun sets from the west along the horizon, the shallower the angle of the setting sun.
2. The earliest sunrise of the year usually occurs before the summer solstice. The exact time will depend in part on your latitude: In the mid-latitudes of the northern hemisphere, it occurs about a week before the June solstice.
3. The last sunsets of the year will occur several days after the solstice. Again, it all depends on the latitude.
4. June 20 marks the beginning of winter in the southern hemisphere.
5. Other planets also have seasons. Uranus, which is tilted almost 98 degrees, has seasons that last 21 years. Mercury, on the other hand, is practically tiltless, which means it has no seasons, either.
