May to September is mostly cool in Siberia, though, against stereotype, June to August is quite warm with temperatures between 10 and 25 °C (50-77 °F). Even Norilsk in the far north reaches highs of 20 °C (68 °F) in July. Though there is not much rainfall in Siberia, when it does come it comes in summer. Irkutsk sees around 25 mm per month at the height of summer, though it can be far higher on the far southern coast around Primorye.  In the warmer months, it is even possible to sunbathe on the beaches of Lake Baikal, the deepest lake in the world and 'pearl of Siberia.’ The lake and surrounding areas prove a great spot to see a vast array of wildlife, including Baikal seals, brown bears, wolves, Siberian musk deer and wild boar. The vast largely uninhabited Putorana Plateau reserve in the far north is ideal for a summer visit, a Unesco world heritage site containing pristine taiga, tundra and arctic desert, as well as untouched cold-water lakes and river systems
