The climate of Calcutta (India)
Calcutta is now also known as Kolkata and is the capital of the federal state of Bengali. The town is one of the largest urban areas in the world with a population of more than 15 million people. Calcutta was one of the most important trading places for the English company. Also at the time of the English colony Calcutta took an important position. Nowadays Kolkata is a sparkling metropolis. It is often considered the intellectual and cultural heart of India. The town has still preserved much of its ancient colonial wealth and architecture. One can still taste the old atmosphere in the numerous clubs and racetracks. In spite of the obviously present poverty there are restaurants, bars and theatres in abundance, where one can enjoy oneself to oneís heartís content.
Calcutta, Kolkata has a tropical savannah climate. The summermonths are warm and humid in which during the sparing dry periods the temperature rises considerably. The month of May is generally speaking the hottest month. At the beginning of the Indian summer rather heavy rain- and hailstorms may occur. The winter is mild and lasts only two months. The monsoon period in Kolkata lasts from June up to and including September. Most rain falls during this period. Due to the extremely dense population the town has to contend with a smog problem. The number of people in Calcutta with respiratory problems and lung diseases such as lungcancer is appallingly high. Although of recent years it has not occurred anymore, in the past Kolkata was completely destroyed by tropical storms or cyclones. The last time was in 1864 and cost the lives of over 60,000 people.
