Halifax’s climate is less severe than might be expected.

This is a result of its location on the shores of the Atlantic Ocean. Winter temperatures are higher and summer temperatures are lower than those encountered in towns farther inland.
Halifax has an eastern-maritime climate, with a short, warm summer and a cold winter. Disturbed, changeable weather is common throughout the year.
Snow depths of greater than 1 cm are seen on about 85 days each year in Halifax.
Comparing Halifax with some other Canadian cities, snow depths of greater than 1 cm are seen on about:
10 days each year in Vancouver, 35 days in Penticton, 53 days each year in Windsor, 65 days in Toronto, 88 days in Calgary, 105 days each year in Fredericton, 109 days in Montreal, 120 days in Ottawa, and 132 days in Winnipeg.
Sunshine is somewhat less common in Halifax than in most Canadian cities owing to Nova Scotia’s notorious fogs. Halifax has over 100 days of mist or fog each year.
Summers in Halifax are pleasantly warm. The best summer weather is usually encountered in mid-summer and late summer when, compared with earlier in the season, fogs are rare.
