Weather in May
Temperature
May's onset brings a subtle temperature rise, moving from a warm 78.4°F (25.8°C) in April to a still moderately hot 85.6°F (29.8°C). Howells, in the month of May, anticipates a consistent average low-temperature of 64.8°F (18.2°C).Heat index
In May, the average heat index is computed to be a very hot 95°F (35°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

The months with the lowest humidity are May and October, with an average relative humidity of 70%.Rainfall
In Howells, during May, the rain falls for 12.8 days and regularly aggregates up to 2.56" (65mm) of precipitation. Throughout the year, there are 161.6 rainfall days, and 34.02" (864mm) of precipitation is accumulated.Snowfall

Sunshine
In Howells, the average sunshine in May is 10.6h.UV index
May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for average individuals.Note: A daily maximum UV index of 7 in May translates into the following instructions:
Guard against overexposure. Protection from sun-induced harm is essential. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
