Ust-Kamchatsk has a subarctic climate (Köppen Dfc) although it has a strong maritime influence resulting in much less extreme winters, cooler summers and much heavier precipitation (both as winter snowfall and summer rainfall) compared to interior Siberia and even the Sea of Okhotsk coast. For instance, mean July maxima are 9 °C or 16.2 °F cooler than those of Yakutsk, whereas January means are around 27 °C or 48.6 °F warmer than the Sakha capital. The effect of the cold Oyashio Current in summer and frequent offshore winds from the Siberian High and Aleutian Low in winter means that, despite the substantial maritime moderation of winter temperatures, annual means are still 7.1 °C or 12.8 °F colder than Ketchikan at a similar latitude on the western coast of North America and 8.9 °C or 16.0 °F colder than Edinburgh at a similar latitude in northwestern Europe.
The windswept locality is largely resembling a barren tundra, although large forests are nearby in more shielded locations.[6]
