Characteristics of  hot weather season (summer) in India - Teachoo.png

The hot weather season (summer) in India is characterized by various weather phenomena and patterns:

  • Temperature Variations : Due to the northward movement of the sun and the shifting of the global heat belt, temperatures in India increase from March to May. In March, the highest temperature is around 38° Celsius on the Deccan plateau. In April, Gujarat and Madhya Pradesh experience temperatures of about 42° Celsius. By May, the northwestern parts of the country often reach temperatures of 45° Celsius. The moderating influence of the oceans keeps temperatures relatively lower in peninsular India.


  • Air Pressure Patterns: During the summer months, the northern part of India experiences rising temperatures and falling air pressure. Towards the end of May, an elongated low-pressure area develops, extending from the Thar Desert in the northwest to Patna and the Chotanagpur plateau in the east and southeast. This creates a trough-like region, influencing air circulation.


  • Hot, Dry Winds (Loo) : The hot weather season is known for the occurrence of "loo," which are strong, gusty, hot, and dry winds that blow during the day over northern and northwestern India. These winds can be hazardous, and direct exposure to them can be fatal. Dust storms are common during May, providing temporary relief by lowering temperatures and sometimes bringing light rain and cool breezes.


  • Thunderstorms and Hail : Localized thunderstorms are prevalent during the hot weather season. They are often associated with violent winds, torrential downpours, and occasionally hail. In West Bengal, these storms are known as the " Kaal Baisakhi ." These thunderstorms provide a mix of intense weather conditions during the summer months.

  • Pre-monsoon showers : Towards the close of the summer season, pre-monsoon showers are common especially in Kerala and Karnataka. They help in the early ripening of mangoes, and are often referred to as ‘ mango showers ’.
