May weather forecast
Canada

May signifies the full bloom of spring across Canada, characterised by warmer temperatures, ample sunshine, and a further decline in snowfall. The onset of favourable weather makes outdoor activities more enjoyable and marks the start of the planting season.

In the northern and central parts of the country, including regions like Yukon, the mercury rises to hover between 6°C (42.8°F) to 14°C (57.2°F), providing some relief from the long, cold winter. However, the nights can still be quite chilly, often falling to near freezing temperatures.

In the southwest, coastal cities such as Vancouver and Victoria enjoy moderate temperatures ranging from 10°C (50°F) to 18°C (64.4°F). The higher temperatures coupled with the Pacific Ocean's influence lead to more rainfall, enhancing the beauty of the local flora.

The Prairies see a substantial increase in warmth during May. Cities such as Edmonton and Winnipeg experience temperatures ranging from 9°C (48.2°F) to 20°C (68°F). The Prairies, known for their sunshine, start to enjoy longer and sunnier days, providing a welcome respite from the harsh winter months.

Over on the Atlantic side, temperatures in cities like Halifax and St. John's oscillate between 7°C (44.6°F) to 16°C (60.8°F). The weather tends to be a mix of sunshine and showers, conducive for the blossoming of spring flowers.

Snowfall becomes increasingly rare in May, limited to the highest mountain peaks and the farthest northern regions. As the ground warms, trees and plants burst into a myriad of green hues, a welcome sight after the winter's stark landscapes.

In comparison to April, May witnesses a significant leap in temperatures. The increased warmth and sunnier days mark a clear shift towards summer. However, spring showers are still prevalent, necessitating the occasional use of umbrellas and raincoats.
