Manitoba Weather
Dual Climates?



Map of Manitoba Canada. Source: Environment Canada.

Manitoba weather is governed by the Prairies Climate, southwest of a line drawn roughly from The Pas, to the southeast corner of the province.

This same area encompasses the "grasslands" and "parklands" of Manitoba, Canada.

North of that line, the weather is under the Northern Climate Region influence.

Continental Climatic Conditions

Located in the middle of Canada, far away from the modifying effects of the oceans, the weather is prone to extremes.

Summers are warm, and often hot and dry, especially south of Lakes Manitoba and Winnipeg. Extreme maximum temperatures in excess of 40C are not uncommon in southern Manitoba. Records of heat are most likely to occur in the Red River Valley.

Winters are normally long and intensely cold. Cold spells can sometimes last for weeks, all over Manitoba!

The transitions from summer to winter weather, and winter to summer, are usually short lived.

Southern Manitoba, like the other Prairie Provinces, is quite sunny. Winnipeg and Brandon, for example, normally receive 2372 and 2329 hours of sunshine per year respectively. July is the sunniest of the twelve months, with over 300 hours!

Manitoba, as its Prairie neighboring provinces, does not receive much precipitation. Yearly totals average between 375mm and 500 mm only, although the lake region will receive around 550mm.

The Weather Of Manitoba
Typical Continental Central

But the strong summer sunshine heats the ground. Thus, a fair portion of the summer rain loses its effectiveness on vegetation, because it evaporates rapidly.

Summer precipitation will be in the form of showers from convective type clouds. Thunderstorms are a common occurrence, some of them severe. The latter will produce the occasional hailstorm, especially when a front of relatively cooler air sweeps the area in the mid to late summer period.

Droughts are not unusual, and may sometimes occur two and three years in a row!

Winter snowfall is relatively light, with annual totals normally around 125 centimeters. However, heavy drifting snow, and the occasional blizzards are a common "nuisance".

Thus, Manitoba's weather can be blissful or a pain ... when it's not monotonous!

Stay tuned, and keep a sharp weather watch!
