The graph below shows Kelowna’s cumulative precipitation from January 1 to December 31. The graph shows six years: 2026, 2025, 2024, 2023, 2022, and 2021. The thick grey line shows the average cumulative precipitation calculated from 50 years of data from 1951 to 2000. The average total cumulative precipitation for 1951 to 2000 by December 31 is 349 mm. An extreme Summer (June 1 to August 31) drought occurred in 2021 and 2023 when cumulative precipitation was less than 50% of normal. 2023 is considered the most destructive wildfire season ever recorded in British Columbia. During 2023, very little rainfall occurred between mid-May and late September. As shown, Kelowna in 2026 is experiencing a severe drought, with cumulative precipitation around 46% of the 1951 to 2000 average. The Kelowna Airport weather station had missing precipitation data from August 21 to September 2, so I used data from the nearby UBC Okanagan weather station for those dates.
