Weather in May
Temperature
Huntsville's transition into May brings a slight rise in the average high-temperature, moving from a warm 78.4°F (25.8°C) in April to a still moderately hot 85.6°F (29.8°C). Nighttime temperature lowers to an average of 65.5°F (18.6°C) in May.Heat index
The average heat index in May is evaluated at a fiery hot 96.8°F (36°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. 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 are particularly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
