The sunset has found its way north as shown in this 2016 photo collage by Abhijit Juvekar in the Northern Hemisphere and in the Winter in the Southern Hemisphere – will take place on June 21, 2019 at 15:54 UTC. That's June 21 at 10:54 am in North America. Translate UTC into your time. For us in the northern hemisphere, this solstice is the longest day of the year. Early dawn. Long days. Late sunsets. Short nights The sun is at its peak every day when it crosses the sky. In the meantime, the winter begins south of the equator.

What is a solstice? The ancient cultures knew that the sun's path over the sky, the length of daylight and the place of sunrise and sunset moved into a year-round period.
They built monuments like Stonehenge to track the sun's annual progress.
Today we know that the solstice is an astronomical event caused by the Earth's tilt around its axis and its motion in the earth orbit around the sun.
It's because the earth does not revolve upright. Instead, our world is tilted 23/2 degrees around its axis. The northern and southern hemispheres of the earth have the task to receive the light and the warmth of the sun most directly.
At the June solstice, the earth is in orbit so that the North Pole of our world is most exposed to the sun. Seen from Earth, the sun is at midday 23 ½ degrees north of the equator directly above the sky. The imaginary line surrounds the globe, known as the Tropic of Cancer, named after the constellation Cancer the Crab. This is as far north as the sun ever gets.
All locations north of the equator have days longer than 12 hours at the solstice in June. Meanwhile, all places south of the equator have days that are shorter than 12 hours.

When is the solstice where I live? The Solstice will take place on June 21, 2019 at 15:54 UTC. That's 10:54 CDT in North America on June 21st.
A solstice takes place for all of us all over the world at the same time. To determine the time of the solstice at your location, you need to translate into your time zone.
Here is an example. In the central United States, for those of us who use central summertime, five hours are deducted from world time. So we get 10:54 CDT at the Solstice in June 2019 (15:54 UTC on June 21 minus 5 equal 10:54 CDT on June 21).
Would you like to know the time at your location? Read the EarthSky article How to Convert UTC to Your Time. And remember, you translate from 15:54 UTC, June 21st.
Sunset over EarthSky Facebook girlfriend Lucy Bee in Dallas, Texas.  Where should I look for signs of the solstice in nature? Everywhere. For all the creatures of the earth, nothing is as basic as the length of the day. After all, the sun is the ultimate source of almost all light and heat on the earth's surface.
If you live in the Northern Hemisphere, you may notice the early dawn and late sunsets and the high sun arc over the sky every day. You may see how high the sun appears at the local lunch in the sky. And be sure to look at your midday shadow. At Solstice, it's your shortest noon shadow of the year.
If you are an outdoors person, you know the peaceful, soothing feeling that accompanies these signs and signals of the longest day of the year.

Is the solstice the first day of the summer? No World Organization has set an official day for the beginning of each new season and for different schools of thought or traditions define the seasons in different ways.
In meteorology, for example, summer starts on 1 June. And every schoolchild knows that summer starts when the last school bell of the year rings.
However, June 21 is perhaps the best known day when summer begins in the northern hemisphere and winter begins on the southern hemisphere. There is nothing official, but it is such a long tradition that we all realize it is so.

It was common among people to appreciate this time of warmth and light.
For us in the modern world, the solstice is a time to recall the reverence and understanding that the early humans had for the heavens. About 5,000 years ago, people placed huge stones in a circle on a vast plain in what is now England, aligning them with the solstice sunrise in June.
We may never understand the full meaning of Stonehenge. However, we know that this knowledge was not limited to just one part of the world. Around the same time Stonehenge was being built in England, two large pyramids and then sphinxes were built on Egyptian sand. If you stood at the Sphinx at the summer solstice and looked at the two pyramids, you would see the sunset just between them.
How does it end? Later in the summer warmer, when June has the longest day? People often ask:
If the June solstice brings the longest day, why do we experience the hottest weather in late July and August?
This effect is called the Delay of the Seasons . For the same reason, it is hotter in the afternoon than at noon. The earth only takes a while to warm up after a long winter. Even in June ice and snow still cover the ground in some places. The sun has to melt the ice – and heat the oceans – and then we feel the hottest summer heat.
Ice and snow are melting since the beginning of spring. Melt and rainwater seeped through the snow on glaciers.
But the outflow of glaciers is not as big as in another month, although the sunlight most directly hits the northern hemisphere.
So wait another month for the hottest weather. It will come as the days begin to shorten, as the earth continues to move around the sun, bringing us closer to another winter.
And so the cycle continues.
