Edmonton is already in record territory for rainfall this June
June 2026 has already become the second-rainiest June ever recorded in Edmonton, and there are still eight days left in the month.
According to Environment and Climate Change Canada (ECCC) meteorologist Chloe Katsademas, the Edmonton region had received 189.9 mm of rain as of early Monday morning (June 22), tying for the second-wettest June on record.
“By the end of the month, we’ll definitely be solidly in second place, but it’s definitely possible to even potentially surpass that record,” she said.
Katsademas explained that several rainfall events have combined to push the month close to record territory, including a storm at the beginning of the month that dropped about 55 mm of rain, several showery days that each brought around 10 mm, and the latest storm system, which dumped approximately 95 mm over two days.
The most recent round prompted an Alberta Emergency Alert for Edmonton, St. Albert, Stony Plain, and Beaumont on Sunday, urging residents to avoid non-essential water use. The alert warned that heavy rainfall over the previous 24 hours had pushed the region’s stormwater system to capacity, with localized flooding and sewer backups reported in neighbouring communities.

For comparison, Edmonton recorded 71.7 mm of rain last June, 67 mm in 2024, 150 mm in 2023, 124 mm in 2022, 26 mm in 2021, and 105 mm in 2020.
The wettest June on record was in 1914, when Edmonton received 216.5 mm of rain. We’ll need about 27 mm more before the end of the month to break that record.
There is a little bit of relief in sight, with Tuesday through Thursday expected to bring drier and sunnier conditions. However, another low-pressure system is forecast to develop on Friday, bringing another round of showers into the weekend.
Beyond that, Katsademas says the next weather system is expected to move slowly across Alberta and into the Prairies, meaning showers will likely continue into next week.
ECCC
With flooding affecting parts of the region, Katsademas recommends keeping an eye on ECCC’s latest weather forecasts and rainfall warnings, and monitoring Alberta Emergency Alerts and other advisories for updates.
