The arrival of July records an average high-temperature of a still tropical 32.9°C (91.2°F), closely related to the 33.7°C (92.7°F) observed in June. During July nights, Karaikal witnesses a consistent average temperature of 27.8°C (82°F).

Heat index

In July, the average heat index is calculated to be an extremely hot 42°C (107.6°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Shield from overexposure. Defense against sun-related harm is required. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
