Summer \Sum"mer\, n. [OE. sumer, somer, AS. sumor, sumer; akin
   to OFries. sumur, D. zomer, OS. sumar, G. sommer, OHG. &
   Icel. sumar, Dan. sommer, Sw. sommar, W. haf, Zend hama, Skr.
   sam[=a] year. [root]292.]
   The season of the year in which the sun shines most directly
   upon any region; the warmest period of the year.

   Note: North of the equator summer is popularly taken to
         include the months of June, July, and August.
         Astronomically it may be considered, in the northern
         hemisphere, to begin with the summer solstice, about
         June 21st, and to end with the autumnal equinox, about
         September 22d.

   {Indian summer}, in North America, a period of warm weather
      late in autumn, usually characterized by a clear sky, and
      by a hazy or smoky appearance of the atmosphere,
      especially near the horizon. The name is derived probably
      from the custom of the Indians of using this time in
      preparation for winter by laying in stores of food.
