Weather in September
Temperature
The transition from August to September sees an average high-temperature of a warm 84.7°F (29.3°C), indicating a minor variance from the prior month. September brings an average low-temperature of 64.6°F (18.1°C) to Altitude.Heat index
In September, the heat index is evaluated at a hot 93.2°F (34°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
