The climate is boreal and precipitation averages are estimated at 1,000 millimeters (39 in), or about three-and-a-half times as much as most of Siberia averages, with most falling as snow. Temperatures in winter are much milder than in Siberia�a typical January day averages ?5 �C (23 �F), while in summer +15.8 �C (60.44 �F) constitutes an average August high. In warm years monthly high averages in July�August reach +18 �C (64 �F) and higher.
Despite the generally high precipitation, the weather is less cloudy than in the adjacent Kuril Islands that are one of the least sunny places in the world, since the city is located behind a peninsula to the north that blocks some of the fog from the Oyashio Current. Oceanic water in Avacha Bay and adjacent bays is also warmer than coastal waters of Kuril Islands and Okhotsk sea coast (except Southern Kuriles and Southern Sakhalin)
