Temperature

September's weather records an average high-temperature of a still hot 31.9°C (89.4°F), showing little deviation from August. During September, Haldia's temperature averages to a warm 26.4°C (79.5°F) at night.

Heat index

During September, the heat index is calculated to be a blistering 44°C (111.2°F). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

The months with the highest humidity are August and September, with an average relative humidity of 80%.

Rainfall

In September, the rain falls for 23.2 days. Throughout September, 173mm (6.81") of precipitation is accumulated. In Haldia, during the entire year, the rain falls for 137.7 days and collects up to 994mm (39.13") of precipitation.

UV index

In September, the average daily maximum UV index is 7. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: An average UV index of 7 in September transforms into this advice:
Guard oneself from overexposure. Defence against sun injury is vital. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat. Notice! The Sun's UV exposure elevates with sand and water reflections.
