Summer Solstice 2025: The Summer Solstice in the Northern Hemisphere for 2025 occurred today, Saturday, June 21, 2025, at 8:12 AM IST (Indian Standard Time). The word “solstice” comes from Latin words “sol” (sun) and “sistere” (to stand still). This refers to the apparent pause in the Sun’s northward movement before it begins to move southward in the sky.
What is the Summer Solstice?
The Summer Solstice is an astronomical event that marks the moment when one of Earth’s poles has its maximum tilt toward the Sun. For the Northern Hemisphere, this means the North Pole is tilted most directly towards the Sun.
Why does it happen?
The Earth’s axis is tilted at approximately 23.5 degrees relative to its orbit around the Sun. This tilt is the primary reason for the seasons. As the Earth revolves around the Sun throughout the year:
During the Summer Solstice, the Northern Hemisphere is tilted towards the Sun, receiving more direct sunlight and longer daylight hours.
Here’s a breakdown of what the Summer Solstice means:
Longest Day of the Year: For the Northern Hemisphere, the Summer Solstice marks the day with the longest period of daylight and the shortest night of the year.
Earth’s Tilt: It occurs when the Earth’s Northern Hemisphere is tilted most directly towards the Sun. This tilt is approximately 23.5 degrees.
Astronomical Beginning of Summer: Astronomically, the Summer Solstice signifies the official start of summer in the Northern Hemisphere. Conversely, it marks the start of winter in the Southern Hemisphere, where they experience their shortest day.
Cultural Significance: Throughout history, many cultures have celebrated the Summer Solstice with various festivals and rituals, often associated with themes of light, vitality, growth, and fertility. Ancient monuments like Stonehenge are even aligned to the sunrise on the Summer Solstice.
Not the Hottest Day: While it’s the day with the most daylight, the Summer Solstice is not usually the hottest day of the year. There’s a “seasonal temperature lag” because the Earth’s land and oceans continue to absorb and release heat for several weeks after the solstice.
