Washington, D.C. – Americans across the country will notice a subtle but important shift this week as solar summer 2025 comes to an end, marking the midpoint between the summer solstice and the autumnal equinox. The nation’s three-month stretch of longest days is officially over, and earlier sunsets are about to become the new normal.
According to the National Weather Service, day length will now decrease steadily from coast to coast as the United States moves closer to autumn. The transition brings shorter evenings and less sunlight for everything from evening commutes to outdoor events and summer activities in cities from Seattle to Miami.
Residents from the Northeast to the Southwest can expect sunset times to inch earlier each evening, affecting plans for outdoor recreation, dining, and travel. Experts recommend taking advantage of remaining summer daylight and being prepared for schedule changes as schools and businesses adjust to the new pattern.
As the countdown to the autumnal equinox continues, weather officials will keep the nation updated on daylight changes and possible impacts to energy use and daily routines. Watch for continued weather and daylight updates as summer slowly gives way to fall.
