Visit our interactive maps for road and weather conditions! We have:

You may have noticed that historical maximum and minimum temperatures are no longer available on the main city page. You can find this information on the Monthly Calendar, simply click on each day to expand the content.

To search for historical weather information on the Website, go to Menu and select Forecasts and Reports. Under Long term, select Monthly calendar. You can view past temperatures, rain and snow amounts, as well as averages and extremes by clicking on each day in the calendar (not all data is available for all locations).

Click on the yellow banner at the top of the page, or use the weather links on the right side of the alert information. Please note that if you have disabled cookies on your browser, clicking on the yellow bar will only refresh the page and the red alert will keep showing up. Cookies must be allowed to use this functionality. Click here for instructions on how to enable cookies.

You can change to Fahrenheit or to Celsius on the desktop site either by clicking directly on the temperature next to the weather icon on the forecast page, or by clicking on the °C or °F at the very top of the page, in the grey bar.  On the mobile website please find these settings by clicking on the "hamburger menu" icon, and scrolling to the bottom of the menu.

The ~ (also known as a tilde) is a mathematical symbol that indicates "approximately".

There are several ways to locate your favourite city. You can use the search box and type in the city name, or you can also locate your cities on the home page map by panning and zooming the map and clicking on the weather icons to take you there. You can also save locations - these will display in the blue navigation bar at the top of every page.

The Barometric Pressure information can be found on your 7 Days forecast page and 36 Hours forecast page. On your 7 Days forecast page below the current observations, click on the small arrow to the right of the“Sunset” icon. The barometric pressure icon is here. On the 36 Hours forecast page in the table of forecast data, Pressure is found in the last line at the bottom.

You can easily switch to Fahrenheit or Celsius by clicking on the large temperature display (the current observation for the location) at the upper left of the forecast page. You can also find this setting at the very top of every page, in the grey bar.

A watch is when there is potential for severe weather to develop. No action is required but you should be aware. A warning is issued when severe weather is happening in your area. It’s time to act to protect your life and property.
Watches, warnings and other alerts are issued by Environment Canada and other government agencies. We do not alter these messages.

Alert banners are posted on theweathernetwork.com by government agencies, particularly when weather or other events are expected or occurring that could pose a threat to public safety, such as poor visibility, dangerous driving conditions and more. In some cases the alert is considered high priority, and appears in full on the page immediately. This is to ensure that website users are aware of the event. Once a user has seen this page, a “cookie” is assigned to the user to represent that the page was viewed. Going forward, the regular forecast page will appear with the alert banner at the top, until the alert ends or is updated and re-issued.

The Severe Weather Outlook is a tool to give you advance notice to the potential development of significant and impactful weather over the next three days.

Not Expected (green): Severe weather is not expected.
Be Aware (yellow): There is a fairly small chance of severe weather impacting you.  Check back later to see if the forecast has updated.
Be Prepared (orange): There is a high enough risk for severe weather that you should keep an eye on the skies and use other features such as the hourly forecast and radar maps to find out exactly when the severe weather is expected.
Be Alert (red): The highest category is reserved for our forecasts where we are confident that severe weather is likely to affect you.  Take precautions such as having a plan B if you have an activity that may be impacted by weather. Again, use other features such as the hourly forecast and radar maps to find out exactly when the severe weather is expected.

Taking into account multiple data points that come from weather prediction models, we measure the potential intensity of severe weather and couple that with the chance of it happening in order to come up with a risk level from 0 to 10.

The risk level displayed is the highest level of the three days forecast in the Severe Weather Outlook. For a more detailed breakdown, use the 36 hour or hourly forecast to learn more about when severe weather is most likely to occur.

Severe thunderstorm, rainfall, snowfall and freezing rain.

The summary table is sorted by highest risk.  The coloured bar at the beginning of each row indicates what action you should take.

While this is not a usual scenario to experience, there could be a few reasons why you might not be seeing Radar image even though it is raining outside:
• Are you experiencing very light rain or drizzle? If so, then this is likely because light rain or drizzle have such a small rain drop size that it is very hard for the radar equipment to detect it. For that reason, very light precipitation does not show up on the radar imagery very well.
• Are you experiencing heavy rain/snow or a thunderstorm that has started very suddenly? If that is the case, then it is possible that the radar simply didn’t have enough time to detect the event. Thunderstorms (or short heavy bursts of rain) can develop very suddenly – sometimes in a matter of just a few minutes. Radar systems scan the sky for any precipitation every 10 minutes, and then it takes another few minutes to process the data and make it available as a ready-to-use image on our digital platforms. So if a burst of rain happened to form right over your area, you could experience some lag time before that rain can appear on the Radar imagery map.
• In addition to above causes, just like any other technology it is possible that Radars could experience occasional down time especially when there is a scheduled maintenance. During this time no Radar imagery will be available in the vicinity of the Radar site.

Thunderstorms (or short heavy bursts of rain) can develop very suddenly – sometimes in a matter of just a few minutes. Our Future Radar feature is great for tracking precipitation when it already started; however, one of its limitations is that it cannot predict if a new storm is expected to develop. For that matter, it is advised that you check the Radar as often as possible on the days when storms are expected in your area to see if any new storms have formed recently.

Our radar maps are great at tracking the already occurring precipitation for six hours into the future. One of their limitations however is that they cannot predict if a new storm is expected to form. If you are seeing rain or snow in the forecast, but nothing on the radar map, it is either because the rain is expected to occur later than six hours into the future OR the rain or snow hasn’t developed anywhere just yet.

One of the limitations of radar is that it cannot predict if a storm is expected to dissipate or change in direction. It is possible that the radar is tracking an already developed storm over your area, while this storm is expected to either dissipate or change in direction.

Radar is great at detecting precipitation, like rain or snow. However, radar systems do not detect clouds. If you would like to see a map of clouds in your area, check out our Satellite map layer instead.

Currently we have a lower resolution cloud imagery available. Smaller clouds or clouds that are considered to be low are generally not detected with lower resolution satellite imagery.

Radar systems are ground-based instruments that detect precipitation that is falling from the sky (rain, snow, etc.), while satellites look down from space and are most commonly used to detect cloud cover.

The way ‘Future Radar’ technology works is by using a simple mathematical algorithm to determine future precipitation movement based on its movement from the past. However, different algorithms can provide slightly different solutions. “Past and Forecast” and “Current and Forecast” Radar maps do happen to use different algorithms; hence you might see some differences especially into the longer lead times.

Radar maps are updated every 10 minutes.

Sometimes mountains, tall buildings, clouds of bugs, or even some atmospheric anomalies within clear air will cause the radar equipment to interpret these objects as precipitation – we call this radar clutter. We have different technologies in place to get rid of most of the radar clutter, but sometimes it might show up on the radar map and mistakenly be interpreted as precipitation.
