Weather in May
Temperature
As Francis steps into May, the average high-temperature holds at a hot 86.4°F (30.2°C), hinting at a minor fluctuation from the prior month. During the month of May, the nighttime temperature falls to an average of 67.3°F (19.6°C).Heat index
The average heat index in May is estimated at a sweltering 96.8°F (36°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
