Weather in May
Temperature
Mount Vernon observes a slight uplift in the average high-temperature with the onset of May, adjusting from April's 78.4°F (25.8°C) to a still moderately hot 85.5°F (29.7°C). In Mount Vernon, the average low-temperature during the month of May is a refreshing 65.5°F (18.6°C).Heat index
The heat index value for May is evaluated at a sweltering 95°F (35°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index values are typically calculated for conditions of shade and a light breeze. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
