Weather in July
Temperature
With July's advent, Port Gibson sees an average high-temperature of a still tropical 91.9°F (33.3°C), subtly shifted from June's 90.3°F (32.4°C). July sees the temperature falling to a mean low of 72.7°F (22.6°C).Heat index
During July, the heat index is calculated to be a burning hot 116.6°F (47°C). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
