Summer is the warmest of the four temperate seasons, occurring between spring and autumn. It is a time of year when temperatures differ depending on the location on Earth; regions near the equator are usually warmer than those positioned over the poles, which receive the least amount of sunlight because of their ice.

A heatwave occurs when the weather is too hot for people to breathe easily or stay healthy. These extreme conditions can cause dehydration, illness and death, especially for elderly or sick people.

Humidity is an issue during the summer months, as well. Many people experience excessive sweating as a result of the high humidity, which can lead to headaches, fatigue, and even depression.

During the summer, schools and universities typically have a break, and families take advantage of the longer days to enjoy vacations and other outdoor activities. In most countries, school ends in late May in Memorial Day weekend, and resumes in September near Labor Day, although dates vary.

June is one of the best sports months of the year, with a variety of sporting events to choose from. The World Cup and Euros are the two most popular, but there are also a number of other big events to look forward to, such as the U.S. Open (golf), Father’s Day, and the Summer X-Games.

In addition, the summer season is a time for festivals and celebrations across the globe. Pagans used to celebrate summer by performing ritual dances around bonfires and for Christians, the summer solstice is a time of celebration for the birth of John the Baptist.
