Q:

How many days are in summer?

A:

Quick Answer

In the Northern Hemisphere, the official summer season begins with the June solstice, which takes place on June 20th, 21st or 22nd each year, and ends with the September equinox, which takes place on September 22nd or 23rd each year; the exact duration of summer depends on when the solstice and equinox will take place and can range from 92 to 95 days. Though summer is associated with warm temperatures and the concept of 'summer break' for students, the season has an official scientific definition, as is defined above. Summer weather in the Northern Hemisphere may begin before the official start of the season and last until after fall has begun with the advent of the September equinox.

Full Answer

While it is officially summer in the Northern Hemisphere, it is winter in the Southern Hemisphere; the exact duration of summer may differ in the Southern Hemisphere. The June solstice marks the longest day and shortest night of the year, marking the extended hours of daylight that characterize summer in the Northern Hemisphere. This is caused by the fact that the Earth is tilted on its axis in such a way as to allow maximum exposure to the sun in the Northern Hemisphere, leading to warmer temperatures and longer days.

  • Q:

    How many hours of daylight does each city get?

    A:

    Duration of daylight hours varies both by geographic location and season; for example, Key Largo, Florida, one of the southernmost cities in the U.S., can get up to 13 hours and 40 minutes of daylight in June and 10 hours and 37 minutes in December, while Barrow, Alaska, one of the northernmost cities in the U.S., experiences extremes of absolutely no daylight during winter months and 24 hours of sunlight in summer. The amount of sunlight a city receives depends more on latitude than longitude, with locales in the Arctic Circle, including Tromso, Norway and Murmansk, Russia experiencing seasonal extremes of daylight availability, while those along the Equator, including Quito, Ecuador and Nairobi, Kenya, have predictably even daylight hours year-round.

  • Q:

    Why are there 365 days in a year?

    A:

    There are usually 365 days in a year because it takes the Earth approximately 365 days to orbit around the sun. However, every four years there is usually a year with 366 days, known as a leap year, because the Earth actually takes slightly over 365 days to circle the sun.
