Weather in May
Temperature
Dexter's transition into May brings a slight rise in the average high-temperature, moving from an agreeable 72.1°F (22.3°C) in April to a warm 80.6°F (27°C). May brings with it a nighttime average temperature of 63.1°F (17.3°C).Heat index
The heat index value for May is evaluated at 84.2°F (29°C). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
