Weather in May
Temperature
The shift from April to May is marked by a slight increase in the average high-temperature, moving from a warm 77.4°F (25.2°C) to a still moderately hot 83.8°F (28.8°C). The average temperature during May nights is registered at a pleasant 68.5°F (20.3°C).Heat index
The heat index value for May is computed to be a tropical 91.4°F (33°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 essentially critical for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
