With June arrives the much-awaited summer in Zachary, Louisiana. The season is distinguished by long, sunny days, supplemented by warm temperatures and a noticeable increase in humidity levels. A remarkable feature of this month is the significant jump in the number of rainfall days. As the month of July approaches, the weather continues to heat up, with temperatures climbing even higher. June notably reaches up to 91°F (32.8°C), marking the start of high-temperature streak sustained throughout the next months.

The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
