Weather in May
Temperature
With the onset of May, the average high-temperature subtly transitions from a moderately hot 81.1°F (27.3°C) in April to a hot 87.4°F (30.8°C). During May, the average low-temperature is an agreeable 68.4°F (20.2°C).Heat index
The heat index for May is estimated at a fiery hot 100.4°F (38°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
