Climate Zone Map Of Canada – Your plant hardiness zone is important information to guide your gardening decisions. In Canada, we have different park zones with variations in each province. Look at the map and find your area number for growing plants, trees, shrubs, and vines, including perennials and perennials.

One common question is whether the Canadian and USDA plant hardiness zone systems are comparable, and the answer is yes.

Climate Zone Map Of Canada

While the USDA system is based on minimum temperatures, the latest Canadian system includes minimum temperatures as well as precipitation, frost-free days, and other variables. When comparing standard zones and defined zones, the difference may be half a zone or more (eg 6a versus 6b). So, they are close.

The purpose of this zone for the home gardener is to guide plant selection. Zone is often the first consideration—will this perennial plant last all year in my climate?—and other growing conditions such as sun, soil, and water will come next.

Our zones range from 0 to 9, where zero is the coldest condition and 9 is the warmest average.

For example, many clematis vines are suitable for zones 4 through 9. This means that they may not survive winter temperatures below zone 4 or climate zone 10 or more, but there are always exceptions to be met.

Some plants and seeds purchased in Canada may use the USDA zone system number, so bear in mind that this is not exact, just a guideline.

We must also consider that our climate is always changing, and zones will change over time, and zone maps are not updated frequently.

A wide-open garden in zone 5 may be exposed to wind and frost, while a walled garden or wind-protected zone 5 garden may be a warmer microclimate that cannot reach the same level.

There is no data available for mappers to follow this exception, but you as a gardener will learn how to grow in your garden.

Your local plant nursery should have the zone range on the plant label. Perennials should be in your zone or lower. Annuals can be higher, but don’t exceed the figures above, of course, because we only grow for one season.

If you know the plant is a good fit for your zone, then look at other needs including sun or shade, soil type, water, and available space to make sure your garden is a good fit.

And the first step is always to make sure that whatever you plant is not invasive in your area. Some invasive plants are available in plant nurseries so don’t assume that what’s available is safe.

Winters can be harsh in many parts of the country, especially in the interior and the Prairie province, which experiences a continental climate, with average daily temperatures approaching 15 °C (5°F), but can drop below 40 °C ( 40 °F). F) with very cold temperatures.

In non-coastal areas, snow can cover the ground for nearly six months of the year, while in the north, snow can last all year round. Coastal British Columbia has a temperate climate, with cool, wet winters. On the east and west coasts, the average high temperature is 20s °C (70s °F), while between the coasts, the average summer high temperature ranges from 25 to 30 °C (77 to 86 °F), with temperature on some beaches. interior locations sometimes exceed 40 °C (104 °F).

Much of Northern Canada is covered in ice and permafrost; However, the future of permafrost is uncertain as the Arctic has warmed three times the global average as a result of climate change in Canada.

Canada’s average annual temperature over land has warmed by 1.7 °C (3.1 °F), with variations of 1.1 to 2.3 °C (2.0 to 4.1 °F) across regions , since 1948.

In southern Canada, air pollution from Canada and the United States—caused by metal smelting, burning coal for electricity, and vehicle emissions—has caused acid rain, affecting waterways, forest growth and agricultural productivity. Canada.

The table below shows the average maximum and minimum temperatures in Canada in various Canadian cities, based on the climatic period from 1981 to 2010 for January and July (usually the months with the lowest and highest average temperatures, but not in every case).

The main Canadian cities that fall outside the continental climate scheme are Vancouver and Victoria. Vancouver has a marine climate, bordering a hot Mediterranean with dry summers. Victoria, BC is the only major Canadian city that enjoys a summer Mediterranean climate. Of Canada’s eight largest cities, Ottawa, Montreal, and Toronto have the warmest summers, Winnipeg has the coldest summers, while Vancouver’s summers are milder than other major Canadian cities.

In mountainous areas such as British Columbia, varying elevations create a microclimate with average temperatures that can vary over relatively small distances. Several small towns south of BC outside Vancouver, for example, have a humid continental climate (Dfb) with average winter and winter temperatures comparable to other parts of the country.

Central Canada and northern Canada experience subarctic and arctic climates, much of which is arid. The region is sparsely populated due to its harsh climate, which dips below 20 °C (−4 °F) on many winter days and very short summers.

Some mountains south of BC also have a subarctic or subalpine climate, making driving conditions especially dangerous, as drivers are unaware of winter road conditions when they come from areas like Vancouver and Kamloops which are much warmer.
