May, the last month of the spring in Castlewood, is another warm month, with temperature in the range of an average low of 65.7°F (18.7°C) and an average high of 85.6°F (29.8°C).

Temperature

In May, the meteorological conditions subtly change with the average high-temperature edging from a moderately hot 78.4°F (25.8°C) in April to a still warm 85.6°F (29.8°C). Throughout the month of May, Castlewood witnesses an average temperature of 65.7°F (18.7°C).

Heat index

In May, the heat index is calculated to be a very hot 96.8°F (36°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 hold particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
