How many days until summer?
Days until summer
The summer solstice is one worldwide instant. Your device shows when that turning point arrives where you are.
This time is an astronomical estimate; the date may be refined when official data is published.
Follow the countdown to the summer solstice in your hemisphere—the turning point for daylight.
The longest daylight is the starting signal
Summer here begins at your hemisphere’s summer solstice: June in the north, December in the south. Your hemisphere receives its longest stretch of daylight, and the annual light cycle reaches a turning point.
Why the hottest day often comes later
The solstice is about sunlight, not a temperature record. Land, water and air continue to absorb and release heat after the longest day, so the warmest part of summer often follows the astronomical start. Your local climate can tell a different story from a nearby city.
What changes after summer begins?
Once the solstice passes, daylight starts to shorten in the summer hemisphere. At first the change can be hard to notice, even while afternoons still feel long. The countdown stops at that turning point, not at the end of hot weather.
Two hemispheres, two summer dates
June’s solstice starts summer north of the equator while winter begins in the south. December reverses the pairing. Use the North and South buttons above for the season where you are, and read the event time in your own time zone.
