Temperature
May signals a minor shift in the average high-temperature, moving from April's moderately hot 75.4°F (24.1°C) to a still warm 81.5°F (27.5°C). During the month of May, Dennis anticipates a mean low-temperature of 63.5°F (17.5°C).Heat index

Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children.
