Weather in May
Temperature
As Semmes welcomes May, the average high-temperature displays a subtle shift, adjusting from a warm 77.4°F (25.2°C) in April to a still moderately hot 83.8°F (28.8°C). Semmes, during May, witnesses an average low-temperature of 67.6°F (19.8°C).Heat index
May's mean heat index is estimated at a tropical 91.4°F (33°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index details are generally centered around shaded locations and a mild breeze. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
