Temperature

An average high-temperature of a still hot 31.8°C (89.2°F) marks May, exhibiting a close resemblance to the conditions in April. Throughout the month of May, Baddamulla reports a steady low-temperature average of 23°C (73.4°F).

Heat index

The heat index value during May is estimated at a blisteringly hot 42°C (107.6°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
