Weather in May
Temperature
May brings a slight increase in the average high-temperature, progressing from a moderately hot 78.8°F (26°C) in April to a tropical 86°F (30°C). The average temperature drops to a refreshing 67.8°F (19.9°C) during the night in the month of May.Heat index
The heat index for May is computed to be a very hot 96.8°F (36°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to 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 human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

In May, the average relative humidity is 75%.Rainfall
The month with the most rainfall is May, when the rain falls for 13.6 days and typically aggregates up to 2.83" (72mm) of precipitation.Snowfall

Sunshine
The average sunshine in May is 9.1h.UV index
In May, the average daily maximum UV index is 6. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.Note: In May, the maximum UV index of 6 suggests this advice:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
