Weather in May
Temperature
A minor escalation in the average high-temperature is seen with the onset of May, moving from 73.4°F (23°C) in April to a still moderately hot 81.1°F (27.3°C). May nights experience a consistent temperature drop to a moderate 60.4°F (15.8°C).Heat index
The heat index value during May is calculated to be a tropical 86°F (30°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.The standards for the heat index are set for locations in shade and under light breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
