Weather in May
Temperature
The onset of May introduces a subtle rise in the average high-temperature, nudging from 76.1°F (24.5°C) in April to a still moderately hot 83.8°F (28.8°C). Despite a noticeable differential from daytime highs, Zimmerman notes an average nighttime low-temperature of 62.2°F (16.8°C) in May.Heat index
In May, the average heat index is calculated to be a tropical 91.4°F (33°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
