Weather in May
Temperature
In May, the average high-temperature marginally rises from 75°F (23.9°C) in April to a still warm 82.2°F (27.9°C). During the nights in May, Grand Prairie observes an average low-temperature of 64.8°F (18.2°C).Heat index
The heat index in May is computed to be a tropical 87.8°F (31°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Realize that the values for the heat index are set for shaded places and light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
