The summer solstice is today

‘Tis the solstice…and you know what that means! Well, I hope you know what that means because I don’t.

Well, literally it means that it’s the longest day of the year so pack in all the activities you can. You’ve got all the time in the world. Visit a museum, set out on a cross-county RV road trip, run a marathon, make pie from scratch, go to an indoor surfing fitness class, head out on a hike, climb a mountain (any mountain will do), swim across the lake (any lake will do), brainstorm what to do with those extra minutes of sunlight. Now is your chance!

Today is the summer solstice, aka the longest day and shortest night of the year in the Northern Hemisphere. Forecast: burnt hotdogs, fireworks, and sunniest warm day you could even imagine.

It is the day on which:

  • The Northern Hemisphere has its longest day
  • The Northern Hemisphere has its shortest night
  • The Northern Hemisphere has the most direct intense solar radiation
  • The sun will be directly overhead at noon as viewed from the Tropic of Cancer
  • Any location north of the Arctic Circle has 24 hours of sunshine
  • The North Pole has been receiving 24 hours of sunshine every day since March 21—yes, the past three months

Today is the summer solstice, aka the official start of summer in the Northern Hemisphere and the longest day of the year. In terms of astronomy, the June solstice marks the sun’s northernmost point in our sky for the year. The sun rises the farthest north on the horizon—and is highest in the sky at local noon.

For the Southern Hemisphere, it marks the longest nights and shortest days. After this solstice, the sun will be moving southward in the sky again.

What is a solstice?

The word solstice comes from the Latin words sol (sun) and stitium (still or stopped). Ancient cultures knew that the sun’s path across the sky, the length of daylight, and the location of the sunrise and sunset all shifted in a regular way throughout the year. In fact, they built monuments to follow the sun’s yearly progress.

The solstice is a time to recall the reverence and understanding that early people had for the sky. Some 5,000 years ago, people placed huge stones in a circle on a broad plain in what’s now England and aligned them with the June solstice sunrise.

We may never comprehend the full significance of Stonehenge. But we do know that knowledge of this sort wasn’t limited to just one part of the world. Around the same time Stonehenge was being constructed in England, two great pyramids and then the Sphinx were built on Egyptian sands. If you stood at the Sphinx on the summer solstice and gazed toward the two pyramids, you’d see the sun set exactly between them.

Today, we know that the solstice is an astronomical event caused by Earth’s tilt on its axis and by its orbital motion around the sun. Indeed, the Earth doesn’t orbit upright. Instead, our world is tilted on its axis by 23½ degrees. Through the year, this tilt causes Earth’s Northern and Southern Hemispheres to trade places in receiving the sun’s light and warmth most directly. In fact, our planet is closest to the sun in January during the the Northern Hemisphere’s winter.

Where should I look for signs of the June solstice in nature?

Everywhere! For all of Earth’s creatures, nothing is as fundamental as the length of the day. After all, the sun is the ultimate source of almost all light and warmth on Earth’s surface.

Living in the Northern Hemisphere, you might notice the early dawns and late sunsets and the high arc of the sun across the sky each day. You might see how high the sun appears in the sky at local noon. And, also be sure to look at your noontime shadow. Around the time of the solstice, it’s your shortest noontime shadow of the year. And in to the out-of-doors, you know the peaceful, comforting feeling that accompanies these signs and signals of the year’s longest day.

Is the June solstice the first day of summer?

No world body has designated an official day to start each new season and different schools of thought or traditions define the seasons in different ways. In meteorology, for example, summer begins on June 1. And every schoolchild knows that summer starts when the last school bell of the year rings.

Yet June 21 is perhaps the most widely recognized day upon which summer begins in the Northern Hemisphere and upon which winter begins on the southern half of Earth’s globe. There’s nothing official about it but it’s such a long-held tradition that we all recognize it to be so. It has been universal among humans to treasure this time of warmth and light.

Is the summer solstice a time to celebrate?

People around the world celebrate this sunny late June day in different ways ranging from sunrise gatherings to bonfire-lit revelry and sauna relaxation. Keep reading to learn about some of the most interesting summer solstice traditions around the globe. You just may get a few ideas for how to celebrate on the big day. Before you make any decisions, though, check out what the summer solstice means for your zodiac to make sure those plans will align with the universe’s larger plan for you.

Perhaps one of the most coveted seats in the world for the northern hemisphere’s summer solstice traditions is on the grounds of the Neolithic structures at Stonehenge in Wiltshire, England. Ingeniously designed to showcase the ascending light of the solstice, the sunrise on this occasion aligns perfectly with a circle carved in stone at the site. Theories of its origin vary but both mystical seekers and history buffs convene here on the solstice to witness an architectural wonder built, some say, to worship deities of the Earth and the sun. Stonehenge is one of the ancient mysteries researchers still can’t explain.

Another wonder of ancient architecture, the pyramids of Chichén Itzá on Mexico’s Yucatán Peninsula are a wonderful place to celebrate the longest day of the year. The precise construction and engineering of the pyramids create a visual display twice a year in which the central pyramid of El Castillo is bathed in pure sunlight on one side and full shadow on the other. Thousands of spectators come from near and far to celebrate the summer solstice in view of this ethereal spectacle in which the pyramid appears to be cut in two.

The indigenous people of New Mexico paid close attention to the sun. In addition to the Pueblo-built sandstone buildings of Chaco Canyon, the state is also home to the Aztec Ruins National Monument in Aztec. Ancestral Pueblo people had a strong relationship with the cosmos. They built the back (north) wall of the monument to perfectly align with the rising and setting sun as it touches the horizon during both the summer and winter solstices. Despite its name, the Aztec Ruins National Monument was not built by the Aztec people (that was just an incorrect guess from early settlers) but instead by the Ancestral Pueblans. It took approximately 200 years to build these structures which date from around the 12th century.

Despite holidays at all times of the year, the summer solstice is when Swedes really celebrate. Is it so surprising that inhabitants of one of the world’s most northerly countries want to celebrate a day full of sunshine and warmth? The Midsummer (or Midsommar) Festival takes place across the country. The day is brimming with ancient agrarian symbolism from walking barefoot in the morning dew for good health to ringing floral crowns around women’s hair to celebrate beauty and fertility. If you want to join in the fun of this summer solstice tradition, stock up on pickled herring for a snack and strawberries topped with whipped cream for dessert.

Why doesn’t the longest day have the hottest weather?

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 lag of the seasons. It’s the same reason it’s hotter in mid-afternoon than at noontime. Earth just takes a while to warm up after a long winter. Even in June, ice and snow still blanket the ground in some places. The sun has to melt the ice and warm the oceans and then we feel the most sweltering summer heat.

Ice and snow have been melting since spring began. Meltwater and rainwater have been percolating down through snow on tops of glaciers. But the runoff from glaciers isn’t as great now as it’ll be in another month even though sunlight is striking the Northern Hemisphere most directly around now.

So wait another month for the hottest weather. It’ll come when the days are already beginning to shorten again as Earth continues to move in orbit around the sun bringing us closer to another winter. And so the cycle continues.

Bottom line: Time to celebrate! Ah, the summer solstice. It’s the longest day of the year, the first day of summer, and the official kickoff for warm-weather festivities.

Worth Pondering…

This is the solstice, the still point of the sun, its cusp and midnight, the year’s threshold and unlocking, where the past lets go of and becomes the future; the place of caught breath.
