Q:

Why do we get more hours of daylight during the summer?

A:

Because of the way the Earth rotates during the summer months, the Earth is closer to the sun, resulting in longer daylight hours. Northern cities have longer daylight hours than those at lower latitudes.

Cities around the world at lower latitudes may have less daylight hours, but the sun's heat and brightness is more intense. This causes higher temperatures and a greater risk of sunburn to those outdoors during the daylight hours.

During the summer, the continental U.S. averages between 14 and 16 hours of daylight every day. Northern cities around the world such as Tokyo or London often have 16 hours of daylight. As the Earth continues its rotation, after the summer solstice, the days become shorter in the Northern Hemisphere and longer in the Southern Hemisphere.

  • 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 days longer than nights at certain times of the year?

    A:

    The National Oceanic and Atmospheric Administration's website explains that the tilt in the earth's axis means that during different times of the year, different parts of the earth are pointed toward the sun, resulting in longer daylight hours. The earth's axial tilt means that days are longer than nights for half the year, and nights are longer than days for the other half.
