Weather in May
Temperature
With the start of May, the average high-temperature marginally shifts from April's moderately hot 77.9°F (25.5°C) to a still warm 84.7°F (29.3°C). An average low-temperature of 63.9°F (17.7°C) is noted during the nights in May.Heat index
May's heat index is computed to be a tropical 93.2°F (34°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
