Weather in May
Temperature
May introduces a minor temperature shift, with average high-temperatures adjusting from April's warm 74.8°F (23.8°C) to a still moderately hot 81.3°F (27.4°C). In Dauphin Island, the average temperature during the nights of May drops to a pleasant 70.3°F (21.3°C).Heat index
For May, the heat index is estimated at a hot 86°F (30°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'apparent temperature' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
