Weather in September
Temperature
The beginning of September brings a minor change in the average high-temperature, shifting from a fiery hot 95.5°F (35.3°C) in August to a hot 88.3°F (31.3°C). During the September nights, an average temperature of 68.9°F (20.5°C) is observed.Heat index
During September, the heat index is computed to be a fiery hot 100.4°F (38°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 quite important for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Prevent overexposure. Protection from the sun's harmful effects is needed. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
