WASHINGTON, D.C. – The summer solstice is a special time when the sun shines its brightest in the Northern Hemisphere.
Here’s a quick overview of what this means.
On June 20 or 21, the summer solstice marks the longest day of the year in the north. This also signals the start of astronomical summer. Meanwhile, in the Southern Hemisphere, it’s the shortest day, ushering in winter.
The term “solstice” comes from Latin. It combines “sol,” meaning sun, and “stitium,” meaning pause. This day represents the peak of the sun’s annual journey, as it reaches its highest point in the sky.
The Earth’s tilt plays a key role here. Throughout most of the year, the axis tilts toward or away from the sun. However, during the solstice, it reaches maximum tilt. Consequently, we experience the longest day and shortest night.
During the Northern Hemisphere’s summer solstice, the upper half of the Earth tilts toward the sun. This creates a day that feels longer. Interestingly, this solstice occurs between June 20 and 22 each year.
But does the solstice affect temperatures? Not really. According to the National Weather Service, the longest day isn’t usually the hottest day of the year. This is because of a natural delay between the peak day and when temperatures actually rise the most.
The Earth and its atmosphere continue to absorb energy beyond what they get from the sun on that day, leading to warmer temperatures later in the summer.
To give you some context, studies show that average high temperatures in the U.S. peak around late July or early August, weeks after the solstice. This means while we enjoy long days, we often wait a bit longer for the true summer heat.
The summer solstice doesn’t just hold scientific significance; it also has cultural importance. Many cultures around the world celebrate this day with festivals, rituals, and outdoor gatherings, embracing the warmth of the sun and the spirit of summer.
In recent years, social media has been buzzing with summer solstice celebrations, with many sharing their experiences and favorite solstice moments using hashtags like #SummerSolstice and #LongestDay. People gather for sunrise yoga or evening barbecues, marking the occasion in fun and meaningful ways.
