Zachary, Louisiana enters its hottest month in July. The summer sun shines predominately, casting long daylight hours.

However, this period marks the peak of the summer heat, with average high temperatures reaching up to 91.9°F (33.3°C).

Temperature

Zachary notes the warmest temperatures in July, with a high average of 91.9°F (33.3°C) and a low of 73.2°F (22.9°C).

Heat index

July's heat index is calculated to be a life-threatening hot 118.4°F (48°C). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
The metrics for the heat index are tailored for both shady environments and light winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
