Weather in December
Temperature
December is the coldest month of the year, registering average temperatures as high as 27.5°C (81.5°F) and as low as 17.9°C (64.2°F).Heat index
For most parts of December, the heat index is calculated to be 28°C (82.4°F). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Heat index determinations are made taking into account the shade and light air movements. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Humidity
The average relative humidity in December is 49%.Rainfall
January and December are months with the least rain when the rain falls for 1.3 days and typically aggregates up to 5mm (0.2") of rain.Sea temperature
In Haldia, in December, the average water temperature is 24.3°C (75.7°F).Note: Consideration of an individual's cold resistance, combined with conditions like sunshine, wind, and temperature, suggests that swimming in 24.3°C (75.7°F) water can be delightful. (Olympic swimming is usually in 25°C (77°F) to 28°C (82.4°F) water.)

January, November and December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for the average person.Note: In December, the maximum UV index of 6 translates into these guidelines:
Fend off overexposure. Sun protection is vital. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Boost your sun resistance with garments that are densely woven yet spacious. Alert! UV radiation becomes sharper due to reflections from sand and water.
