September weather forecast
Palani, India

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

Temperature

The commencement of September is characterized by an average high temperature of a still hot 32°C (89.6°F), bearing no significant change from August. September's nights observe an average temperature of 23.2°C (73.8°F).

Heat index

In September, the average heat index is estimated at a torrid 38°C (100.4°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

The average relative humidity in September is 62%.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
