Canada - weather in July

July is the central month of summer in Canada, and is the warmest of the year almost everywhere, except in the east, on the Atlantic coast (see Saint John's, Halifax), where the warmest month is August.
The average temperatures are a few degrees above freezing in the extreme north, where the climate is polar (see Alert), while they are mild, around 15/17 °C (59/63 °F), in the inland areas of the center-north, where the climate is cold continental (see Inuvik, Yellowknife). In the south, July is a fairly warm month, in fact the daily averages exceed 20 °C (68 °F) in the warmest cities (see Montreal, Toronto, Ottawa). On both coasts, temperatures are a little cooler.
Precipitation is generally weak in the north, in the Arctic areas, where, however, we are in the wettest period of the year. Even in the west-central, in the Great Prairies (see Edmonton, Calgary, Regina), where the cold season is quite dry, summer is the rainiest season: the rains are moderate, 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 driest season, especially in July and August, because in these months the North Pacific High often arrives.
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, 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 to about 0 °C (32 °F).
The days in July are long, especially in the north, where the sun never sets in the areas closest to the Pole (see Alert). Further south, roughly north of the 55th parallel, where the day lasts more than 17 hours, especially at the beginning of the month, the white nights occur, in which the sun sets but does not it gets completely dark even at midnight.
From July to October, Nova Scotia (see Halifax) can occasionally be reached by hurricanes from the Atlantic Ocean, which turn north-east after affecting the Caribbean. They usually arrive weakened because they have to cross a cold sea, however, they can still bring heavy rains and strong winds.
On both coasts, the sea is cold for swimming.
