Quebec City Weather

The reliability of the forecast hinges on the underlying data. This service uses the Open‑Meteo API, which combines outputs from several global and regional numerical weather models maintained by national meteorological agencies. These models are updated multiple times per day, and Open‑Meteo exposes them via a public JSON interface that supports cross‑origin requests. By blending high‑resolution regional models with broader global ones, the forecast takes into account topography, land cover and urban effects specific to Quebec City. Because the API is free and requires no registration, you always access the latest runs without managing keys or quotas. Keep in mind that uncertainty grows with lead time: forecasts beyond a week should be read as general trends rather than exact values.

At the top of the page you’ll find four key indicators. Temperature is measured two metres above ground and represents the ambient air temperature. Feels‑like temperature (humidex or wind‑chill) combines temperature and wind speed, capturing how warm or cold conditions feel on your skin: high winds can make winter days feel much colder, whereas high humidity can make summer heat oppressive. Wind speed is the ten‑minute average speed in kilometres per hour, helping you gauge breeziness and potential gusts. Relative humidity expresses how saturated the air is with moisture; high humidity makes summer days muggy and can enhance fog, while very low humidity in winter can dry out skin. These variables update with each new model cycle and are a useful reference when comparing the seven‑day and monthly outlooks.

Quebec City lies in a humid continental climate zone and experiences pronounced seasonal contrasts. Winters are long and severe: temperatures often fall below −20 °C, and the city’s record low is a chilling −36.7 °C during an exceptional cold snap. Snow blankets the region from November into April, with seasonal totals approaching three metres. Spring arrives late and can be muddy as snowmelt swells the St‑Lawrence and nearby rivers. Summers are warm and humid; highs typically reach the mid‑20s °C in July, which is also the wettest month with roughly 120 mm of precipitation and frequent thunderstorms. Autumn brings colourful foliage and a gradual cool down, with the first frosts appearing by early October. Overall the city sees about 1,190 mm of precipitation annually and roughly 170 freezing days, making it a place where the weather remains an integral part of daily life.

To make the most of your plans, consult the forecast frequently and adjust to seasonal conditions. Before venturing out, look not only at the temperature but also the feels‑like value and precipitation risks; in winter, layer insulating clothing and protect exposed skin from wind‑chill. During spring, monitor rain totals and flood advisories—snowmelt can quickly raise river levels. Summer heat and humidity call for regular hydration and attention to lightning warnings; consider scheduling outdoor activities in the morning or evening to avoid midday peaks. In autumn, be ready for rapid temperature swings with a wind‑ and rain‑proof jacket. Use the interactive map to spot areas with stronger winds or approaching storm cells and alter your route if necessary. By combining these tools, you can enjoy all four seasons while staying safe and comfortable.
