Omsk Oblast experienced record-breaking rainfall in April 2026, shattering an 83-year-old weather milestone. Meteorologists confirmed the new high after tracking unusually heavy downpours across the region. The Ob-Irtysh Hydrometeorological Service recorded a new single-day precipitation record on Sunday, April 26, 2026. Omsk received 19 millimetres of rain in just 24 hours, surpassing the previous record of 18.4 millimetres set on the same date in 1943.
