Weather in May
Temperature
The start of May brings a subtle rise in the average high-temperature, moving from a warm 75.7°F (24.3°C) in April to a still moderately hot 84°F (28.9°C). An average nighttime temperature of 63.3°F (17.4°C) is noted during the month of May.Heat index
In May, the heat index is evaluated at a hot 91.4°F (33°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
