Environment Canada Trois-Rivières 14-Day Forecast

Environment Canada itself does not publish an official 14-day daily forecast through its main portal. Its core offerings are a 7-day daily outlook and a 24-hour hourly breakdown with updated conditions every six hours. For anything beyond a week out, you’ll need to cross-reference with third-party services that aggregate model data.

“40 percent chance of flurries early this morning with risk of freezing drizzle. Clearing this afternoon. High plus 4.”

— Environment Canada Official Forecaster

Where the gap exists

The federal site breaks forecasts into two formats: the hourly view with temperature, wind, precipitation probability, and wind chill for each of the next 24 hours; and the 7-day grid showing daily highs, lows, and conditions. Extended outlooks beyond seven days are not part of that official suite.

Comparison services and what they show

Ventusky, a European-based visualization platform, provides a 14-day summary for Trois-Rivières (coordinates 46.35, -72.55) showing daily highs ranging from 8°C to 23°C and several rain events mid-week. Ventusky (Weather model aggregator) draws from multiple global forecast models including those used by Canadian meteorologists. The Weather Network similarly publishes 14-day POP (probability of precipitation) and temperature ranges for the city, though these originate from its own model interpretation rather than Environment Canada directly. The Weather Network (Canadian forecast provider) typically shows 30–60% POP on rain days with temperatures within 2–3°C of what Environment Canada reports for overlapping periods. The discrepancy between December 2025 data from Environment Canada (showing -6°C flurries) and Ventusky’s January 2026 readings (indicating 2.7°C) reflects both natural forecast drift and the fact that the two sources pulled data on different dates under different weather patterns.

How to use both together

Start with the Environment Canada 7-day forecast for a reliable near-term picture backed by official meteorologist analysis. Then check The Weather Network or Ventusky for extended trends, but treat anything beyond day 7 as directional rather than predictive. The further out you look, the wider the error margin grows on any weather model.

Bottom line: Environment Canada gives you official 7-day and 24-hour detail. For the 14-day outlook, rely on third-party aggregators but remember those are model interpretations, not official government forecasts.

Environment Canada Trois-Rivières Weather

The main weather page for Trois-Rivières sits at meteo.gc.ca and presents current observations alongside the 7-day forecast. It draws live data from the Trois-Rivières Airport meteorological station, giving you the most immediate picture of what’s happening right now.

Current conditions at the airport

At the latest observation, Trois-Rivières Airport recorded -0.4°C with 99% humidity, north-northwest winds at 8 km/h, a wind chill of -3°C, and barometric pressure at 101.4 kPa. Environment Canada (Federal Meteorological Service) provides these readings directly from automated station equipment. Humidity that high means fog or mist is possible if conditions shift, even if it’s not currently showing in the forecast.

7-day forecast summary

The 7-day forecast for Trois-Rivières shows Monday sunny with a high of 15°C and low of 7°C, Tuesday mixing sun and cloud with a high of 17°C and low of 9°C, and Wednesday turning cloudy with rain and a high of 14°C dropping to 6°C overnight. Environment Canada 7-Day Forecast These temperatures run above the seasonal normals for this time of year (high of 6°C, low of -4°C), suggesting a warm pattern for the region. UV index is listed at 3 for today but can reach 6 or higher on clear sunny days — the kind of reading that means sunscreen if you’re spending time outdoors.

Nighttime minimums and wind chill

Tonight’s forecast calls for a low of -5°C with few clouds and northeast winds at 20 km/h near midnight, producing a wind chill near -12°C. Environment Canada Tonight Forecast That distinction matters if you’re walking to a car or waiting for transit — the air temperature and what it actually feels like on exposed skin can differ by seven degrees or more.

The catch

The airport station sits about 2 km from central Trois-Rivières. Urban heat island effect and microclimates near the Saint-Maurice River can make downtown readings occasionally differ by a degree or two from what the airport shows.

Environment Canada Trois-Rivières App

Environment Canada does not maintain a single branded app for the general public. Instead, its weather data feeds the apps and services that Canadian users rely on daily — from phone manufacturers to broadcast weather providers.

How official data reaches your phone

The federal government’s weather data flows through the Environment and Climate Change Canada forecast portal, which is the source that Apple Weather, Google Weather, and various Canadian weather apps pull from behind the scenes. When you check weather on an iPhone, you’re often looking at data that originated with Environment Canada, even if the interface shows a different brand name. This means the accuracy is fundamentally the official forecast — but the presentation and extra features depend on the third-party app you choose.

App features for Trois-Rivières data

AccuWeather, for example, offers hourly RealFeel temperatures and wind gust data for Trois-Rivières that go beyond what the federal site displays by default. AccuWeather (Commercial forecast provider with RealFeel metric) A reading of 20°C RealFeel at 1 PM with 73% humidity and 100% cloud cover gives you the rather than just the thermometer reading. The Weather Network app similarly layers in precipitation probability percentages and regional radar maps that make it easier to plan around incoming rain.

Download and setup for Canadian weather

To access Environment Canada-sourced data for Trois-Rivières, open your existing weather app and search for “Trois-Rivières QC” or use the coordinates 46.346, -72.561 if the app supports location-by-coordinates. Alternatively, bookmark the official page directly — meteo.gc.ca/en/location/index.html?coords=46.346,-72.561 — for the most direct access to the government forecast without any intermediary interface.

The upshot

There is no official Environment Canada app to download. Your best move is to use any weather app set to Trois-Rivières, which automatically pulls from federal data, or bookmark the government forecast page for direct, unfiltered access.

Environment Canada Trois-Rivières Hours

Environment Canada operates primarily as an online service for the public. The federal meteorological office does not maintain a walk-in service counter in Trois-Rivières city center — weather information is accessed digitally rather than in person.

Office schedule and contact details

Environment Canada’s public-facing operations are largely web-based, with forecast data updated continuously and available around the clock through the official portal. There is no publicly listed local office hours for the Trois-Rivières area specifically. For general inquiries, the federal department’s main contact channels operate on standard business hours in the Ottawa timezone (Eastern). Environment Canada (Federal government service)

Regional variant at Trois-Rivières-Ouest

Environment Canada does cover a neighboring location at Trois-Rivières-Ouest (coordinates 46.325, -72.605) with its own 7-day forecast. Environment Canada (Nearby station coverage) If you live west of the city center, that station may actually be closer and produce slightly more relevant microclimate data for your exact address.

Service availability

The weather data itself is available 24 hours a day, 7 days a week through the website. Severe weather warnings — including the risk of freezing drizzle noted in current forecasts for the region — issue automatically when thresholds are met, regardless of time of day. There is no offline service for forecast access; you’ll need an internet connection or cell signal to pull current data.

Hourly Forecast for Trois-Rivières on Environment Canada

The hourly forecast page on Environment Canada gives the most granular official view available: temperature, conditions, precipitation probability, wind speed and direction, and wind chill for each of the next 24 hours, updated every six hours.

“Chance of flurries 40% with W 30 gusts 50 km/h wind chill -14”

— Environment Canada Official Hourly Forecast

Next 24 hours detail

On December 12, 2025 at 10:00 EST, Environment Canada recorded -6°C at Trois-Rivières with a 40% chance of flurries, west winds at 30 km/h gusting to 50 km/h, and a wind chill of -14°C. Environment Canada Hourly Forecast From 11:00 through 17:00 that same day, temperatures held between -6°C and -4°C with the same 40% flurries probability and winds continuing from the west at 20–30 km/h with gusts to 50 km/h. Starting at 18:00, conditions shifted to mainly cloudy with -5°C, dropping precipitation chance to 0% and reducing wind to 15 km/h from the west — wind chill settled around -10 to -11°C.

Temperature and winds overnight

Through the overnight period from midnight to 06:00 on December 13, partly cloudy skies kept temperatures between -6°C and -8°C with variable winds at just 5 km/h and wind chill ranging from -8°C to -11°C. Environment Canada Hourly Forecast By 07:00 on December 13, conditions changed to a mix of sun and cloud with temperatures around -9°C — the kind of early morning shift that makes checking the hourly update worthwhile if you have an outdoor commute.

Precipitation chances across the day

The 40% precipitation probability during flurries on December 12 was notable because it carried a specific warning: risk of freezing drizzle in the early morning hours. Environment Canada Warning Data Freezing drizzle creates icy sidewalks and roads even when air temperatures are only slightly below freezing — the combination of flurries and drizzle meant slippery conditions were a real concern for that period. By 18:00, the precipitation chance dropped to 0%, meaning the evening stayed dry.

What to watch

The hourly page updates every six hours, not continuously. If you’re checking in the late evening, you may be looking at the 18:00 update — the next refresh won’t come until midnight. Plan your outdoor decisions around the most recently published hour block.

Frequently asked questions

What website provides Environment Canada forecasts for Trois-Rivières?

The official federal forecast page for Trois-Rivières is at weather.gc.ca (Environment Canada). Bookmark the location-specific page or search directly for “Trois-Rivières weather” on the site. The hourly forecast is at weather.gc.ca/en/forecast/hourly/ with the coordinates appended.

How accurate are Environment Canada weather predictions?

Environment Canada forecasts are among the most reliable for Canadian locations, backed by official meteorologist analysis and data from airport weather stations. The 24-hour hourly forecast is generally accurate within 1–2°C for temperature; the 7-day daily forecast tends to be reliable through day 5 with growing uncertainty after that. Environment Canada (Federal Meteorological Service)

Can I get alerts for Trois-Rivières weather from Environment Canada?

Environment Canada issues severe weather alerts — including wind warnings, freezing drizzle advisories, and special weather statements — automatically when conditions meet national criteria. You can subscribe to these alerts through the federal government’s emergency alerts system or through apps that carry Environment Canada alert feeds. The risk of freezing drizzle noted in current forecasts is the type of condition that triggers an alert if it materializes.

What devices support Environment Canada weather apps?

Because third-party apps source data from Environment Canada, virtually any device with a weather app can display it. Apple Weather, Google Weather, and The Weather Network app all work on iOS and Android. The official website works on any browser. No dedicated Environment Canada app needs to be installed — your existing weather app is already connected to the source.

How often are Environment Canada forecasts updated for Trois-Rivières?

The hourly forecast page updates every six hours with new data blocks. The 7-day forecast updates at least twice daily. Current conditions from the airport station refresh automatically with each new observation. During active weather events, updates may come more frequently, but there is no continuous live feed — the schedule runs on six-hour cycles.

Does Environment Canada provide radar for Trois-Rivières?

Environment Canada operates a network of Doppler radar stations across Canada. The Trois-Rivières area falls within coverage of the federal radar network, and radar imagery is available through the main weather portal. Precipitation type (rain versus snow versus mixed) shows up on radar, helping you anticipate whether a coming system will bring flurries, rain, or freezing precipitation.

What is the difference between Environment Canada and other weather sites?

Environment Canada is the official federal government meteorological service — the source that other services ultimately draw from. Private providers like The Weather Network, AccuWeather, and Ventusky take that data and add their own layers: extended outlooks, RealFeel temperatures, precipitation probability breakdowns, and visualization maps. For anything beyond a week out, you are looking at model interpretations, not official government forecasts. The Weather Network (Commercial forecast provider) and Ventusky (Model aggregator) both fit this category.

For anyone planning outdoor activities in Trois-Rivières, the choice between sources comes down to timeframe. The official government site handles the next 24 hours with precision; third-party services extend the horizon at the cost of certainty. Bookmark the federal page, set up alerts for severe weather, and you will always have the most reliable data at your fingertips.
