Weather in September
Temperature
August's transformation into September witnesses an average high-temperature of a moderately hot 85.5°F (29.7°C), noting a minor change from the preceding month. An average low-temperature of 70.2°F (21.2°C) is expected during September.Heat index
During September, the heat index is estimated at a sweltering 96.8°F (36°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.The heat index's values are generally associated with conditions in shade and light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
