September, the first month of the autumn in Lopezville, is still a hot month, with temperature in the range of an average low of 77.2°F (25.1°C) and an average high of 92.5°F (33.6°C).

Temperature

September implies a soft temperature shift, with average high-temperatures reducing from August's torrid 98.2°F (36.8°C) to a hot 92.5°F (33.6°C). Lopezville's nighttime temperature in September falls to an average of 77.2°F (25.1°C).

Heat index

The heat index value during September is appraised at an extremely hot 109.4°F (43°C). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
