As Earth turns toward the warmth of the sun, the Summer Solstice 2025 marks the official arrival of summer in the Northern Hemisphere on Friday, June 20. It’s the longest day of the year — not just by tradition, but by science.
☀️ What Is the Summer Solstice?
At 10:42 p.m. EDT (0242 GMT on June 21), the sun reaches its northernmost point from the celestial equator, a position known as the solstice point. During this moment, the sun appears directly overhead along the Tropic of Cancer at latitude 23.5°N, approximately 1,400 miles south of Tokyo, Japan.
This celestial event marks the beginning of summer in the Northern Hemisphere and the transition toward shorter days as the sun begins its southward migration.
📍 Where and How to See It
In Philadelphia, for example, the sun will reach its highest point in the sky at 1:02 p.m. EDT, standing 73 degrees above the southern horizon. That’s a towering height — equivalent to stacking seven clenched fists held at arm's length above the horizon.
This high solar arc means extended sunlight: exactly 15 hours of daylight in many locations — the longest of the year.
🌎 Why It Matters
The solstice isn’t just a pretty sunset or a calendar flip — it affects our energy, moods, plant life, and even cultural celebrations across the globe. From Stonehenge ceremonies to Midsummer festivals, this day has inspired awe for millennia.
For astronomers, gardeners, and nature lovers alike, the solstice is a moment of transition — from waxing to waning light — and a powerful reminder of Earth’s celestial rhythm.
☀️ Celebrate the Sun!
Get outside, catch the sunrise or sunset, and celebrate the sun’s peak moment in our skies. Whether you're watching from a park bench or planning a solstice bonfire, today is a time to soak up the light and embrace the start of summer.
