KATHMANDU, Dec 7: Meteorologists have predicted very low chances of winter rainfall this year, with any precipitation expected to be scattered and minimal—similar to last year.
Sharing an early winter outlook, experts at the Department of Hydrology and Meteorology said that most parts of the country are likely to experience warmer-than-average temperatures, with reduced winter precipitation.

“Like last year, the chances of winter rain remain very low in most areas. Even if it occurs, it will be very light and scattered,” said Sudarshan Humagain, a meteorologist at the Department. “This winter, too, temperatures are expected to remain higher than average in many places, except for a few particularly cold days.”
According to the Department, maximum temperatures across most regions are likely to stay above average this winter. On Thursday, Kathmandu recorded a maximum temperature of 19.3°C and a minimum of 9°C. The coldest temperature ever recorded in Kathmandu was –3.5°C on January 11, 1978.
Winter in Nepal spans mid-December to mid-February. Meteorologists warn that during winter, reduced wind flow prevents fine dust particles from dispersing, causing them to remain close to the ground—posing significant health risks. In contrast, stronger winds in the summer help disperse dust particles to higher altitudes.
Experts note that air pollution peaks during winter, especially during overcast days, which can be particularly hazardous. Pollution levels are typically highest during morning and evening hours when cold air traps dust and pollutants close to the surface.
Environmental experts have also pointed out that valley areas like Kathmandu—surrounded by hills—tend to trap fine dust particles during winter. They say the monsoon season is generally more favorable for public health, as rainfall helps clear pollutants from the atmosphere.
