Weather in September
Temperature
With the beginning of September, the average high-temperature shows a small decrease, transitioning from a hot 91.6°F (33.1°C) in August to a warm 83.5°F (28.6°C). Nighttime temperature dips to a mean of 64.4°F (18°C) during September.Heat index
For most parts of September, the heat index is evaluated at a hot 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
