Temperatures in the Langtang region vary greatly due to the extreme difference in altitude in the region. Most of the annual precipitation occurs from June to September. In fall (October – November) and spring (April – May), days are warm and sunny, and nights cool. In spring, rain at 3000m elevation often turns to snow at higher elevations. In winter from December to March, days are clear and mild but nights cold.

As in all mountain regions, weather is most impacted by changes in elevation and topography. Expeditions throughout the Langtang are at lower altitudes than those through the Khumbu or Annapurna region. Days are warmer on average and summers can be humid at lower elevations.
