Weather in September
Temperature
September's arrival signals a moderate reduction in the average high-temperature, easing from a sweltering 95.7°F (35.4°C) in August to a hot 87.4°F (30.8°C). In Rendon, September nights cool down to an average of 69.6°F (20.9°C).Heat index
The heat index for September is calculated to be a very hot 95°F (35°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
