Editing Irkutsk (section)

===Climate===
Irkutsk has a borderline [[humid continental climate]] ([[Köppen climate classification]] ''Dwb'', bordering ''Dwc'', [[Trewartha climate classification]] ''Dcbc'', bordering on ''Ecbc'').

Irkutsk is characterized by an extreme variation of temperatures between seasons. It can be very warm in the summer, and very cold in the winter. However, [[Lake Baikal]] has a tempering effect, giving Irkutsk temperatures that are slightly less extreme than at similar latitudes elsewhere in Siberia. The warmest month of the year is July, when the average temperature is {{convert|+19|C}}; the highest temperature recorded being {{convert|+37.2|C}}. The coldest month of the year is January, when the average temperature is {{convert|−17.6|C}}, and record low of {{convert|−49.7|C}}. [[Precipitation (meteorology)|Precipitation]] varies widely throughout the year, with July being the wettest month, when precipitation averages {{convert|107|mm|sp=us}}. The driest month is February, when precipitation averages only {{convert|9|mm|sp=us}}. Almost all precipitation during the Siberian winter falls as fluffy, dry snow.{{Citation needed|date=January 2024}}
