Weather in May
Temperature
Saint Francisville in May observes a minor temperature shift, with average high-temperatures adjusting from 77.5°F (25.3°C) in April to a still moderately hot 84.6°F (29.2°C). Saint Francisville, during the nights of May, experiences an average temperature drop to a refreshing 64.8°F (18.2°C).Heat index
Throughout May, the heat index is estimated at a very hot 95°F (35°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. 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. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
