Monsoon Arrives Early
Kathmandu – The monsoon has made an early entrance into Nepal, arriving from the eastern region on the night of May 29, nearly 15 days ahead of the usual onset date of June 13. This early arrival marks a significant deviation from the norm and has already brought rainfall to much of Koshi Province.
According to the Department of Hydrology and Meteorology, the monsoon system has spread over several eastern districts, delivering light to moderate rain. While the clouds have moved in early, the monsoon has yet to become fully active across the country. It may still take several days for the system to gain strength and extend its effects to all provinces.
Historically, Nepal’s monsoon lasts from mid-June to late September. Last year, it began slightly ahead of schedule on June 10 and lingered until October 12. The early arrival this year could influence both the weather and agriculture sector significantly.
The department has projected higher-than-average rainfall for much of the country during the June to September monsoon season. Areas including eastern Karnali, northern Lumbini, and most parts of Gandaki Province have a 55–65 percent probability of experiencing above-normal rainfall. Other provinces such as Sudurpaschim, Bagmati, and Koshi are likely to see a 45–55 percent chance, while Madhesh Province is expected to have a 35–45 percent probability.
This forecast has generated cautious optimism among farmers and policymakers, as stronger monsoon rains could boost agricultural output and offer a positive push for the struggling economy. However, the prospect of heavy rainfall also brings increased risk of natural disasters, including floods and landslides, especially in geographically vulnerable areas.
As of now, the rest of the country remains under the influence of westerly winds and local weather systems. The full impact of the monsoon is expected to gradually reach these regions in the coming days. Authorities are closely monitoring the situation and are advising preparedness for both the opportunities and threats that may come with the early monsoon.
