Kyrgyzstan is a country with four seasons, with winters occurring during the months of November to February. Because winter is made even colder by Siberian winds, staying in the mountains during this time is very difficult and could be dangerous. The average lowest temperature in the country during winter is -24°C (-11.2°F).

Spring begins in the months of April and May, but nights can still be freezing. The weather becomes pleasant from the middle of May to the middle of June, though many of the mountain passes in the country will still be filled with snow.

Summer reaches its peak from the end of June to the middle of August, when temperatures reach an average of 32°C (89.6°F) and a maximum of 40°C (104°F). During this time, mountain valleys are much cooler than the rest of Kyrgyzstan. Most of the rainfall in the country occurs from spring until early summer.

The best time to visit Kyrgyzstan is from July to September, when the weather is cool but the scenery is still bright and cheery from the spring and summer seasons. If you are thinking of trekking and camping in the mountains, avoid the months of March, April, September, and early October – these are the months of greatest avalanche danger.
