Bengaluru. This is the period of the highest relative humidity of 76%. Undeterred by the rains, the city's life continues, with the weather adding a picturesque charm to the cityscape. Despite the rainfall, there's a certain vigor and freshness in the air that defines the monsoon months in the city.

Heat index
July's average heat index is calculated to be a tropical 32°C (89.6°F). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
