Weather in May
Temperature
May's arrival is noted with a slight increase in the average high-temperature, moving from a warm 80.1°F (26.7°C) in April to a tropical 86°F (30°C). During May, the nighttime temperature averages to a comfortable 66.4°F (19.1°C).Heat index
The heat index value for May is appraised at a sweltering 95°F (35°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
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. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. 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 especially vital to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
