Weather in September
Temperature
As El Sauce welcomes September, the average high-temperature is noted at a still hot 31.8°C (89.2°F), closely aligning with the preceding month. September witnesses an average low-temperature hovering around a moderately hot 23.5°C (74.3°F).Heat index
Throughout September, the heat index is estimated at an extremely hot 43°C (109.4°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
