Weather in May
Temperature
The average temperatures reach their apex in May, averaging 30.7°C (87.3°F) at the high end and 29°C (84.2°F) at the low end.Heat index
For most parts of May, the heat index is estimated at a scorching 40°C (104°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
