Mongolia’s landlocked location gives rise to an extreme continental climate, giving an average of 260 sunny days a year but with wide variations in temperature between summer and winter.
Ulaan Baatar is the world’s coldest capital, and across the country winter temperatures regularly drop to -30°C and below. Only the southern Gobi is truly hot in the summer months, though this is also when the little rain that does fall each year is most likely. Given the severity of the winter months travel beyond Ulaan Baatar is only really feasible during the warmer months between May and October.
