September weather forecast
Chandigarh, India

Temperatures in September are marginally lesser than August, but the city remains warm before the onset of the cooling October month. Chandigarh receives dense rainfall in this month - a notable decrease from August but still more than October. September sees relatively fewer sunshine hours compared to October. The prevalence of high humidity levels makes the weather feel damp. With the season of rainbows and drizzles wrapping up, the city starts prepping to bid farewell to monsoons.

Temperature

Chandigarh observes a minor difference in average high-temperatures between August's 32.6°C (90.7°F) and September's 31.4°C (88.5°F). Chandigarh, during the month of September, experiences an average low-temperature of 21.4°C (70.5°F).

Heat index

For most parts of September, the heat index is calculated to be 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.
Heat index determinations are made taking into account the shade and light air movements. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Note: The maximum UV index, 6 during September, leads to the following recommendations:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Consider carefully! The reflective quality of snow can almost double the intensity of the Sun's UV radiation.
