May weather forecast
Coimbatore, India

The last month of the pre-monsoon summer, May, is another torrid month in Coimbatore, India, with an average temperature ranging between min 24.7°C (76.5°F) and max 36.2°C (97.2°F).

Temperature

With the start of May, Coimbatore measures an average high-temperature of a still very hot 36.2°C (97.2°F), not significantly differing from April's 37.7°C (99.9°F). Coimbatore sees an average low-temperature of 24.7°C (76.5°F) during May.

Heat index

May's heat index is appraised at a blazing hot 49°C (120.2°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
