Weather in June

June ushers in the height of Summer in Mandeville, Louisiana with temperatures varying from 75°F (23.9°C) to as high as 90.1°F (32.3°C). This intense heat, which serves as the backdrop to the sunniest month on the calendar, forms a notable contrast against the modest temperatures of earlier months. The Summer Solstice’s arrival blesses the city with the year's lengthiest days, thus maximizing daylight hours up to 14.1 per day. Coupled with an uptick in rainfall days to 19.3, it evokes a truly tropical climate. Despite the elevated precipitation during this period, June’s luxuriously warm temperatures hold a prominent attraction.

Temperature

Heat index

In June, the average heat index is appraised at an extremely hot 107.6°F (42°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
