The length of the summer season is usually three months. This is applicable for both Northern and Southern Hemispheres. However, global warming has been changing the weather patterns in the world.
Northern and Southern Hemisphere
In the Northern Hemisphere it commences on 20 June and ends on September 23. In the Southern Hemisphere it usually commences on 22 December. The end date is usually on the 23rd of March. Due to the rotation of the Earth, when it is summertime in one hemisphere it is winter on the opposite end.
Keep in mind that these dates are only approximations. In some countries, the length of the summer season can be much longer. In some Southeast Asian countries, the season starts in late February and ends in June.
The most visible and widely felt element of the season is the heat. This is due to the fact that the region is exposed to the Sun. Owing to the tilt and movement of the Earth, the heat differs in the hemispheres and regions. What this means is that some places on Earth are hotter than others. For example, it is usually hotter in the Middle East and India than in America or Europe.
The length of the summer season (three months) is still prevalent in most locations. However some countries experience some rainfall in the early or late periods of the season. For this reason it can sometimes be difficult to determine when the period has concluded. Rather than a specific end date, some countries now use periods to determine its ending (i.e., the hot period ends on the final two weeks of September).
Activities of Animals and Plants
The warm weather is the reason why plant and animal activity are usually at their peak. Various types of flowers, plants and vegetables achieve their full growth at this period. Although spring is when the fruits and flowers start to appear, it is in the warm months that most fruits reach the full growth potential.
Animal activities are also more pronounced during this time. The length of the summer season provides birds plenty of time to hunt for food, create nests and care for their offspring. A trip to forests will reveal that most of the animals resume their activities as well.
Other Signs of the Season
The period is also associated with times of relaxation and fun among people. In the United States and other places it is the time when people head to the beaches. It has also become associated with going to the cinemas.
In other nations, it is the peak of tourist activity. A lot of countries (particularly in Asia) see an increase in tourist arrivals at this time. The reason is that the warm weather entices tourists to visit the beaches or go diving.
While the length of the summer season so far remains constant, it might change. Already, some regions have been experiencing typhoons in the midst of the dry season.
Conversely, some of the warmest days have been recorded during the supposed rainy season. Owing to the fluctuating weather patterns, determining the time when the hottest period will commence may prove more difficult.
