Weather in May
Temperature
The shift into May is characterized by a subtle rise in the average high-temperature, transitioning from April's pleasant 73.2°F (22.9°C) to a moderately hot 81.1°F (27.3°C). Harpersville reports an average low-temperature of 60.3°F (15.7°C) during the nights of May.Heat index
The heat index in May is computed to be a hot 86°F (30°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
