Weather in September
Temperature
The arrival of September sees a recorded average high-temperature of a still hot 87.3°F (30.7°C), showing little divergence from the previous month's conditions. In the month of September, the average temperature dips to a warm 73.6°F (23.1°C) during the night.Heat index
The heat index value during September is computed to be a sweltering 100.4°F (38°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 especially crucial for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
