Weather in September
Temperature
September's average high-temperature stands at a still tropical 32.5°C (90.5°F), showing little deviation from August's 33.4°C (92.1°F). Challapalle experiences a consistent average temperature of 25.9°C (78.6°F) throughout the nights in September.Heat index
Throughout September, the heat index is computed to be a blisteringly hot 44°C (111.2°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
