Weather in May
Temperature
Fairnelson's transition into May is noticed by a slight rise in the average high-temperature, advancing from a moderately hot 77.9°F (25.5°C) in April to a still warm 85.3°F (29.6°C). Fairnelson's temperature in May declines substantially from daytime highs, settling at a consistent average of 63.1°F (17.3°C) during the nights.Heat index
In May, the heat index is evaluated at a torrid 95°F (35°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Sunshine
The average sunshine in May is 10.3h.UV index
The average daily maximum UV index in May is 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.Note: The UV index of 6 in May translates into these instructions:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
