Canada - weather in June

June is the first summer month in Canada.
The average temperatures are around freezing in the extreme north, where the climate is polar (see Alert), while they are quite mild in the inland areas of the center-north, where the climate is cold continental (see Inuvik, Yellowknife). In the south, the daily averages exceed 15 °C (59 °F), reaching 20 °C (68 °F) in the warmest cities (see Montreal, Toronto). On both coasts, temperatures are a little cooler.
Precipitation is generally weak in the north, in the Arctic and Subarctic areas, where it is scarce all year round. Instead, in the west-central, in the Great Prairies (see Edmonton, Calgary, Regina), where the cold season is quite dry, summer is the rainiest season, and sometimes thunderstorms can break out.
In the extreme west, on the coast of British Columbia (see Vancouver), where it rains a lot most of the year, summer is instead the relatively dry season, because it is often protected by the North Pacific High.
In the extreme south, in the Great Lakes area (see Toronto) and in Québec (see Montreal, Ottawa), rainfall is frequent, as in the rest of the year.
Even in the east, on the Atlantic coasts (in New Brunswick, Nova Scotia and Newfoundland, see Saint John's, Halifax), the rains are frequent, moreover, in this area, the temperature increases with a delay, and in June there may still be some cold days. In addition, fog can form in summer.
Although Canada is considered a cold country, there can be heat waves in the summer, during which the temperature can reach or exceed 35 °C (95 °F).
At night, on the other hand, it can sometimes get cold even in the south, especially in the Great Prairies, where the temperature can drop slightly below freezing.
June is the month of the year when the days are longest in the northern hemisphere, and on the 21st, the day of the solstice, the sun never sets at the Arctic Circle. Further north (see Alert, Inuvik), there are areas where the sun never sets throughout the month. Further south, roughly north of the 55th parallel, where the day lasts more than 17 hours, there are the white nights, when the sun sets but it doesn't get completely dark even at midnight.
On both coasts, the sea is cold for swimming.
