Weather in September
Temperature
The onset of September brings an average high-temperature of a still hot 87.4°F (30.8°C), nearly matching the August temperature. During the month of September, Improve's nighttime temperature lowers to an average of 68°F (20°C).Heat index
In September, the average heat index is estimated at a sweltering 102.2°F (39°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Research indicates the heat index considers values in shaded locales and with light winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
