These widgets aim to provide useful information from web sites without having to fully parse their HTML and reload them every time. Just a mouse-throw away, these widgets should give you all you need while procrastinating and thinking about the next gear purchase, or the next ski trip :)

This is free software. You are free to use these widgets without any charges for as long as you want. If you feel generous, your donation of $5CAD, or any other sum, will help me improve the existing widgets and create new ones.

To install download the widget, uncompress, right-click and select Open.

Canadian Weather Information from Weather Office's Web Site. The default OSX weather widget differs wildly between what it reports and the values given by the definitive Canada weather source: Environment Canada's Weather Office web site. This widget incorporates all the available Weather Office information including Weather Warnings, Air Quality Information, Weather Watches, Humidex and Windchill information and, now, 7-day forecasts!


- Double-click on the main panel to switch between text and graphical forecasts.

- Windchill (when present) is displayed under the current temperature in blue

- Humidex (when present) is displayed under the current temperature in red

- Current weather image (when present for the location)

- Weather warnings result in the location to be displayed in red

- Clicking on the location text will take you to the web page provided by Weather Office

- A pop-up menu in the back allows the user to set what interval the widget updates at if it is constantly displayed.

- Selecting the “Default location” checkbox will cause this location to be remembered as the default for WeatherOffice, i.e., when a new widget is loaded it will always display this location instead of asking you to select one yourselves. Local per-widget preferences are still honoured if you have more than one widget running at the same time.

  1. -Air quality information: for locations for which Weather Office reports Air Quality Information (Toronto, for example) the current temperature reading will be colored according to the color scheme that Weather Office uses for pollution (link): blue means low, red means high.

  2. -Mouse-over the temperature to see the current AQHI (for reported locations only)

  3. -When Warning or Watch is in effect, mouse-over the city name to see the type of warning, or click to go to the warning or watch page

The widget supports English and French locales.

What’s new in this version


canadian weather forecast

This widget displays an animation of the latest satellite images of North and South america, including the North Atlantic and Pacific oceans. Separately, all radar coverage for Canada can also be viewed as an animation, including multi-province zones such as the Pacific or Maritimes. 6-hour models for the Upper atmosphere air circulation are also made available.

Users can choose how fast the images rotate, how many images an animation includes and which area will be displayed. The size of the displayed image is also  adjustable.
