Weather in July

July, like June, is another tropical summer month in Istrouma, Louisiana, with an average temperature varying between 91.9°F (33.3°C) and 73.8°F (23.2°C).

Temperature

During July and August, Istrouma experiences its peak temperatures, averaging a high-temperature of 91.9°F (33.3°C).

Heat index

The heat index for July is computed to be a life-threatening hot 118.4°F (48°C). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
