Weather in September
Temperature
The advent of September brings a slight shift in average high-temperature, moving from a sweltering 95.5°F (35.3°C) in August to a tropical 88.3°F (31.3°C). Tool, during September nights, observes an average temperature of 68.9°F (20.5°C).Heat index
The heat index value for September is calculated to be a torrid 100.4°F (38°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
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. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
