September weather forecast
Palani, India

The last month of the rainy (monsoon) season, September, is another tropical month in Palani, India, with an average temperature varying between 32°C (89.6°F) and 23.2°C (73.8°F).

Temperature

As August transitions into September, Palani records an average high-temperature of a still tropical 32°C (89.6°F), consistent with the preceding month. Throughout September, an average low-temperature of 23.2°C (73.8°F) is expected in Palani.

Heat index

The heat index for September is estimated at a fiery hot 38°C (100.4°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
One should consider that heat index numbers are for shaded settings and light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
