Weather in May
Temperature
A minor escalation in the average high-temperature is seen with the onset of May, moving from a pleasant 72.9°F (22.7°C) in April to a moderately hot 81°F (27.2°C). During May, Gardendale records an average temperature of 60.6°F (15.9°C) at night.Heat index
May's heat index is calculated to be a tropical 86°F (30°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
