Weather in July
Temperature
Grand Gulf experiences a recorded average high-temperature of a still hot 91.9°F (33.3°C) in July, closely aligned with June's 90.3°F (32.4°C). Grand Gulf anticipates an average minimum temperature of 72.7°F (22.6°C) in the month of July.Heat index
For July, the heat index is evaluated at a blazing hot 116.6°F (47°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. 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 hold particular significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
