Weather in September
Temperature
September indicates a minor shift in the average high-temperature, from August's very hot 95.5°F (35.3°C) to a hot 88.3°F (31.3°C). Nighttime temperatures in September average to an agreeable 68.9°F (20.5°C).Heat index
September's heat index is evaluated at a fiery hot 100.4°F (38°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
