Weather in May
Temperature
May's arrival is noted with a slight increase in the average high-temperature, moving from a moderately hot 76.3°F (24.6°C) in April to a still warm 83.3°F (28.5°C). In the month of May, the average low-temperature usually rests at an enjoyable 65.7°F (18.7°C).Heat index
May's average heat index is estimated at a hot 91.4°F (33°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Heat index determinations are made taking into account the shade and light air movements. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
