Weather in May
Temperature
May's onset records an average high-temperature of a still moderately hot 84.9°F (29.4°C), a near match to April's 79.9°F (26.6°C). Throughout the nights in May, an average low-temperature of 67.1°F (19.5°C) is noted.Heat index
During May, the heat index is estimated at a hot 93.2°F (34°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
