Temperature
With the onset of May, the average high-temperature subtly transitions from a warm 75°F (23.9°C) in April to a still moderately hot 82.2°F (27.9°C). The temperature in Addison dips to an average of 64.8°F (18.2°C) during May nights.Heat index
The heat index for May is evaluated at a tropical 87.8°F (31°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
