P.E.I. Climate

The weather on PEI weather is never boring. While we have our fair share of winter storms and rainy days, our summers are pleasantly warm and our winters fairly temperate (compared with other parts of Canada) - and you never have to worry about tornados or monsoons. All in all, even if the weather is never constant, it is also never extreme, and as a result we live in a very comfortable climate. Here are some statistics:

Summers are pleasantly cool. Daily highs are normally in the mid to low twenties. Maximum temperatures exceed 30 ° C only once or twice a year.

Winter temperatures reflect the presence of sea ice, becoming colder later in the winter after the surrounding sea ice freezes. Bitterly cold temperatures below -18C occur on only four or five nights a year in any winter and thaws can occur in all the winter months.

Cloud, mist, haze and a bit of fog conspire to keep sunshine totals in PEI below the national average of 1925 days, but not far below. The Island is relatively free of fog year-round since neighbouring provinces help to shelter PEI from fog-bearing southerly winds off the cool Bay of Fundy and the Atlantic Ocean. Days with fog number 37 a year, as compared with 101 at Halifax, Nova Scotia and 106 at Saint John, New Brunswick.

Monthly precipitation totals are greatest in the late fall and early winter, exceeding 100 mm monthly from October to January due to more frequent storm activity at that time of year.

Measurable snowfalls are frequent over the long winter season from November to April. The Island is one of the snowiest parts of Canada. However, because the snow comes and goes througout the winter, there is an appreciable cover for only about three-quarters of the snow season, which lasts from late November to April 20, a period of aobut 145 days. Heavy snowfalls of 12 cm or more average about five a year, with one or two of them leaving as much as 25 cm of snow.
