Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from a fiery hot 95.5°F (35.3°C) in August to a hot 88.9°F (31.6°C). Throughout September, the average low-temperature records at an enjoyable 67.6°F (19.8°C).Heat index
For most parts of September, the heat index is estimated at an extremely hot 104°F (40°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Know that the heat index computations account for shaded terrains and slight winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
