Weather in May
Temperature
The shift into May is accompanied by a modest temperature increase, with the average high-temperature edging up from a moderately hot 78.4°F (25.8°C) in April to a still warm 85.6°F (29.8°C). Merrydale sees an average low-temperature of 65.7°F (18.7°C) during May.Heat index
During May, the heat index is appraised at a torrid 96.8°F (36°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
