Ponneri's July showcases an average high-temperature of a still tropical 32.8°C (91°F), hardly distinct from June's 34.2°C (93.6°F). The nights of July are characterized by an average low-temperature of 28.4°C (83.1°F), subtly descending from daytime highs.

Heat index

It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
