Summer is the warmest season of the year. The regions near the equator are usually warmer than those lying near the poles. The curve of the Earth gives these places the most sunlight. The areas around the Earth's poles have ice, which reflects a lot of the sun's rays.

The summer equinox occurs when the sun is directly above the equator. When the seasons are based on the position of the Earth in relation to the sun, it is called summer. The summer season in the Northern Hemisphere starts on June 21. The sun is at the greatest angle toward the North Pole. The South Pole is tilted toward the sun during summer in the Southern Hemisphere.

The summer and autumn equinoxes are the summer and autumn solstices. The summer solstice is the day of the year in which the sun is up the longest, while the autumnal equinox is when night and day are the same length.

There is more than one definition for summer. A meteorological season is defined as the 12 months of the year being divided into four seasons with three months each. January and February are summer to the south, while June, July and August are summer to the north. Over the rest of the year, temperatures tend to be lower than during these months.

The history of summer and the U.S. road trip

It's road trip time in the summer. Hundreds of thousands of families and friends take advantage of sunny, warm weather and hit the road, heading for beaches and lakes, national parks and reserves.
