Quebec City is set for a soggy Tuesday, Aug. 24, with steady rain beginning the day and a significant risk of thunderstorms later in the afternoon and evening. Forecasters expect a cool, damp start before temperatures climb into the low 20s Celsius, but the improving warmth will be accompanied by more unsettled weather.
Morning: steady rain, mild temperatures
The day begins cool and wet, with morning temperatures around 18°C and a high probability of precipitation. Winds are expected to be light at roughly 11 km/h, making conditions damp but not blustery. Sidewalks and streets will be wet, and visibility can be reduced at times where rain is heaviest.
- Morning temperature: about 18°C
- Wind: light, near 11 km/h
- Conditions: steady rain, high chance of precipitation
Afternoon: warming with thunderstorm risk
Temperatures are expected to rise to around 23°C in the afternoon, but the milder air will arrive alongside more vigorous weather. Forecasters put the chance of thunderstorms at roughly 60% for the afternoon period. Winds should remain generally gentle, near 12 km/h, though localized gusts can accompany storm cells.
These storms could produce brief heavy downpours. Drivers and commuters should watch for sudden changes in road conditions and reduced visibility. Event organisers and anyone planning outdoor activities are advised to keep an eye on the sky and prepare shelter options.
"Thunderstorms are expected mainly in the afternoon and evening, with light rain in the morning."
Evening: thunder persists, cooler but still wet
Into the evening, temperatures will cool to about 19°C, but the thunderstorm risk remains around 60%. Winds are forecast to ease to near 7 km/h, which may make for a wet — and at times noisy — night outdoors. Residents should consider moving social gatherings indoors and ensuring pets have dry, sheltered spaces.
Power interruptions are possible with stronger storm cells; preparations such as having a portable phone charger on hand can help should outages occur.

Practical advice for Quebec City residents
Local conditions around the St. Lawrence and within older neighbourhoods can change quickly during thunderstorms. Officials and weather services recommend basic precautions to reduce disruption and risk.
- Carry a waterproof jacket or umbrella and wear water-resistant footwear for the morning commute.
- If you must travel in the afternoon or evening, allow extra time for wet roads and possible delays.
- For outdoor events, have a contingency plan to move activities indoors or to sheltered areas.
- Keep a charged phone or portable charger handy in case of brief power interruptions.
- Ensure pets have a warm, dry place to stay during thunder and heavy rain.
While the day will not be unusually warm, the contrast between the cooler morning and the milder afternoon is enough to fuel unstable air, which is why thunderstorms are forecast. Residents should monitor local alerts and updates from meteorological services for any severe weather warnings.
