Weather in May
Temperature
A subtle rise in the average high-temperature is observed during May, adjusting from a warm 79.9°F (26.6°C) in April to a hot 86.7°F (30.4°C). Old Glory's May nights represent a significant downturn from the day's heat, with an average temperature of 64.2°F (17.9°C).Heat index
For most parts of May, the heat index is computed to be a hot 89.6°F (32°C). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
