Temperature

In Donaldsonville, the month of July is known for its highest average temperatures, reaching a high of 91.6°F (33.1°C) and a low of 72.7°F (22.6°C).

Heat index

During July, the heat index is estimated at a burning hot 113°F (45°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
