Weather in September
Temperature
September's onset introduces a mild reduction in the average high-temperature, from a fiery hot 95°F (35°C) in August to a tropical 88.2°F (31.2°C). During September, Chandler consistently records a temperature low averaging a comfortable 67.6°F (19.8°C).Heat index
For most parts of September, the heat index is estimated at a very hot 100.4°F (38°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Notice this! Nearly double the intensity of the Sun's UV radiation can be caused by snow reflection.
