Weather in May

May, the last month of the spring in Welikanda, is another tropical month, with an average temperature varying between 34.2°C (93.6°F) and 24.5°C (76.1°F).

Temperature

Welikanda's average high-temperature in May is a still tropical 34.2°C (93.6°F), marking an insignificant difference from the 34.9°C (94.8°F) of April. The average temperature during May nights dips to a moderately hot 24.5°C (76.1°F).

Heat index

During May, the heat index is evaluated at a blazing hot 49°C (120.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
