Weather in September
Temperature
The advent of September brings a slight shift in average high-temperature, moving from 94.3°F (34.6°C) in August to a still tropical 88.7°F (31.5°C). Bloomington in September experiences a low-temperature average of 73.2°F (22.9°C).Heat index
For September, the heat index is calculated to be a blisteringly hot 104°F (40°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to 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 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. 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. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
