Temperature

The advent of September signifies a minor shift to an average high-temperature of a still hot 88.2°F (31.2°C), aligning closely with August. Linden cools down to an average low-temperature of 72.7°F (22.6°C) throughout the month of September.

Heat index

The heat index value during September is calculated to be a blisteringly hot 105.8°F (41°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Prevent overexposure. Protection from the sun's harmful effects is needed. 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. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
