Weather in May
Temperature
A soft shift in the average high-temperature is noticeable in May, transitioning from 78.6°F (25.9°C) in April to a still moderately hot 84.7°F (29.3°C). An average low-temperature of 66.7°F (19.3°C) marks the month of May.Heat index
The average heat index in May is appraised at a fiery hot 95°F (35°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Consider that heat index readings are for situations in the shade and light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
