Mumbaiites sweated it out on Thursday, as the moisture level in the air during the day rose both in the suburbs and south Mumbai.
According to weathermen, south Mumbai recorded 98% humidity, 22% above normal, during the day, which dropped to 79% in the evening. The suburbs recorded 80% humidity during the day and 55% in the evening. High levels of moisture in the air prevent evaporation of sweat, which cools the body.
Officials from the India Meteorological Department (IMD) said the increase was because of day-to-day fluctuations. “The weather system prevailing over the Arabian Sea that resulted in rain the last weekend has moved westwards, depositing moisture along the coastline. We expect current conditions to continue for the next few days,” said VK Rajeev, director, western region, IMD.
On Wednesday, the humidity levels in south Mumbai and the suburbs were 87% and 77% respectively.
Even as the city edges closer towards winter, night temperatures continued to stay at least 3 degrees above normal in the city on Thursday. While the temperature at Colaba was 26 degrees Celsius, 3.7 degrees above normal, it was 23.4 degrees Celsius (3.3 degrees above normal) at Santacruz. “When the weather systems result in upper-air circulation over the sea, the effect is an increase in humidity along the coast. As the humidity rises, the night temperatures rise and day temperatures stabilise, but are above normal,” said GP Sharma, vice-president, meteorology, Skymet, private weather forecasting agency.
Day temperatures on Thursday were similar to previous days, with the suburbs recording 35.3 degrees Celsius, 2.4 degrees above normal and south Mumbai recording 33.6 degrees Celsius (0.9 degrees above normal).
Weathermen predicted partly cloudy skies for Friday with the day and night temperatures at 35 degrees Celsius and 23 degrees Celsius respectively.
