The hilly side of the country continues to experience a gradual transition in weather patterns as the influence of monsoon winds weakens and westerly air systems begin to dominate parts of western Nepal. According to the Meteorological Forecasting Division (MFD), Thursday’s weather is expected to remain partly cloudy in the hilly regions and mainly fair in the rest of the country.
The Division’s latest analysis indicates a shift from the monsoon-dominated system that characterized the past few months to the early stages of post-monsoon conditions. While most parts of Nepal will enjoy fair weather, a few hilly areas may experience brief spells of light rain due to the residual moisture and local wind activity.
Westerly Winds Influence Western Nepal
The Meteorological Forecasting Division has reported that westerly winds are currently influencing many places across the western parts of Lumbini, Sudurpaschim, Karnali, and a few areas of western Gandaki Province. This atmospheric shift is typical during this time of year as the southwest monsoon begins to retreat gradually toward the Bay of Bengal.
These westerly winds are bringing mild cloud cover and slightly cooler air to the western hills and adjoining regions. However, the Division clarified that no significant weather disturbances are expected. The current system will mainly contribute to occasional cloud formations and localized light showers in elevated regions, particularly in the afternoon and evening.
The presence of westerly winds marks the onset of changing seasonal dynamics that often pave the way for clearer skies and stable weather in the coming weeks. The weakening of the monsoon is a signal that Nepal is now entering its post-monsoon or autumn weather phase, typically characterized by pleasant days and crisp mornings, ideal for tourism and outdoor activities.
Weakened Monsoon and Local Wind Systems
The MFD’s analysis also highlights that the influence of monsoon and local wind systems has significantly weakened across the country. This seasonal decline is expected in early October as the moisture-laden monsoon winds lose strength and frequency.
Throughout the past few days, weather stations across Nepal have recorded reduced humidity and lower rainfall activity, indicating the monsoon’s retreat. The monsoon, which brought varying degrees of rainfall across Nepal from June through September, has now started to lose momentum, leaving behind more stable atmospheric conditions.
With the weakening of these systems, most parts of the country, particularly in the southern plains and central hills, are likely to experience clearer skies, better visibility, and dry conditions over the next several days.
Evening and Nighttime Forecast
According to the Division’s bulletin, tonight’s weather will also follow a similar pattern. The skies are expected to remain partly cloudy in the Koshi Province and mainly fair in the rest of the country. The Division, however, mentioned the possibility of light rain in one or two hilly areas of Koshi, Bagmati, and Gandaki Provinces.
Meteorologists note that such minor rain activities are normal during this transitional period and are often localized, lasting only for a short duration. The temperature in the hilly and mountainous areas is expected to drop slightly during the night, offering cooler and more comfortable weather.
Outlook for the Coming Days
Weather experts suggest that the coming days will likely bring mostly stable and dry conditions across Nepal. As the monsoon retreats, the country typically witnesses clearer skies, reduced rainfall, and moderate temperatures, conditions that are especially favorable for travel and tourism activities.
However, residents and farmers in the hilly regions are advised to remain cautious, as isolated rainfall could still occur in some areas. These showers, though light, might affect harvesting activities and rural transportation routes temporarily. Meanwhile, with clearer atmospheric conditions, air visibility is expected to improve significantly, particularly in the Tarai belt and major urban centers such as Kathmandu, Pokhara, and Butwal.
Transition to Autumn Weather
The gradual withdrawal of the monsoon marks one of the most awaited seasonal changes in Nepal. The post-monsoon period brings sunny days, stable temperatures, and minimal rainfall, signaling the start of the autumn season, the country’s peak time for tourism, trekking, and outdoor festivals.
Meteorologists anticipate that within the next two weeks, monsoon influence will fully subside, giving way to the clear blue skies and dry air typical of mid-October. This period also coincides with Nepal’s major festivals such as Dashain and Tihar, during which favorable weather conditions are both culturally and economically significant.
