Weather in May
Temperature
May's onset witnesses a minor shift in the average high-temperature, moving from a moderately hot 74.8°F (23.8°C) in April to a still warm 81.9°F (27.7°C). During the month of May, the temperature generally drops to a low average of 69.8°F (21°C).Heat index
The heat index value during May is estimated at a hot 87.8°F (31°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
