Temperature

May is the month when Perumbakkam's temperatures reach their peak, with averages of 36.8°C (98.2°F) and lows of 29.4°C (84.9°F).

Heat index

May's heat index is calculated to be a blazing hot 52°C (125.6°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

In May, the average relative humidity is 62%.

Always remain cautious. Unprotected skin and eyes are prone to swift harm. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
