CLIMATE AND WEATHER IN NEPAL
Nepal’s climatic conditions differ from region to region, based on geographical features.
Northern summers are cold and extreme winters, while southern summers are warm, and winters are moderate.
Nepal has five seasons: spring, summer, moonsoon, autumn and winter.For a 1,000 m altitude rise, average temperature decrease of 6 ° C occurs.
Summer temperatures in Terai reach 37 ° C and higher in certain places, winter temperatures vary from 7 ° C to 23 ° C in Terai.
For mountainous areas, hills and valleys summers are temperate, although winter temperatures can drop below freezing.
Around the Kathmandu Valley has a pleasant and welcoming climate with typical summer and winter temperatures of 19 ° C-35 ° C and 2 ° C-12 ° C respectively.
The Himalayas serve as a shield to winter chilly winds from Central Asia and shape the northern boundaries of monsoon weather patterns.
They receive eighty percent during the monsoon (June-September).
The total annual rainfall is 1,600 mm, although it differs by eco-climatic regions, such as Pokhara’s 3,345 mm and Mustang’s 300 mm.
An important reality is that traveling in and across Nepal has no seasonal limitation.
Also in December and January, when winter is at its worst, warm sun and dazzling views compensate.
Unlike other trekking areas in Nepal, the perfect time to explore is spring and autumn.
Nepal has categorized four seasons such as autumn (from September to November), winter (from December and February), spring (from March to May) and monsoon (from June to August).
High passes are normally closed during the winter season, particularly the Thorong-la pass on the Annapurna Circuit, Chola pass, Renjola pass, Khongmola pass on the Everest region, Ganjala pass, Lauribina pass, Gosaikunda pass in Langtang region.
During the autumn season, the mountain nights are chilly, yet the bright sun develops warm daytime temperatures.
At a higher altitude, temperatures vary from 20 ° C to -10 ° C at night.
Morning is normally bright, and then afternoon clouds add up, vanishing at night, creating beautiful starry skies.
Quick and simple mid-hill trek is the safest at this period.
Heavy snowfalls across mountain regions, mostly during January, February and March
Spring season offers warmer temperatures, yet more intense storms and high altitude snowfall.
The lower elevations present birds and flowers, especially rhododendrons.
By the end of March, haze-caused by dust from India’s plains and smoke from local fires still blur distant views.
It also gets hotter in the area below 3000 feet
Trekking in Monsoon may be achieved by the careful or qualified.
Rain, mist and fog can be encountered almost every day, but clouds rarely break for stunning mountain views.
Typical indicators of entering a storm like cirrus clouded sky or dropping barometric pressure may be confusing.
The perfect hiking season is autumn (from September to November) and spring (from March to May).
Short hikes and certain tea house treks in winter or summer at Tea may also be undertaken.
You must be careful while trekking for unexpected weather shifts.
Before the journey, therefore, trekking equipment should be carefully selected.
Sudden rain storms or snow are a probability to acknowledge.
