Weather in August
Temperature
Morrisville observes a minor difference in average high-temperatures between July's 89.8°F (32.1°C) and August's 87.4°F (30.8°C). August is noted for a mean low-temperature of 69.6°F (20.9°C).Heat index
August's heat index is appraised at a very hot 100.4°F (38°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
