Weather in September
Temperature
The shift into September reveals an average high-temperature of a still hot 88°F (31.1°C), closely mirroring August's climate. Throughout September, an average low-temperature of 73.6°F (23.1°C) is experienced.Heat index
The heat index value during September is appraised at a scorching 105.8°F (41°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
