Weather in September
Temperature
Brusly, Louisiana, records an average high-temperature of a still hot 87.3°F (30.7°C) as September arrives, nearly mirroring the previous month's climate. In September, Brusly reports a consistent average low-temperature of 70.3°F (21.3°C) during the nights.Heat index
The heat index for September is calculated to be an extremely hot 104°F (40°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. 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 highly important 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. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
