In Winnipeg, precipitation is distributed unevenly throughout the year, but overall its quantity is small. In winter, snow typically falls, whereas rain prevails during the warm season. Despite the presence of wet days year-round, the total volume of precipitation remains modest.

The period with a slightly higher amount of precipitation falls on late spring and summer, approximately from May to September. The highest amount of precipitation, averaging 3 mm per month, falls in June and September. July stands out with the highest frequency of precipitation, counting on average 12 wet days, although the total precipitation volume in this month is about 2 mm. In May, an increased frequency of precipitation is also observed with 11 wet days and 2 mm of precipitation. It is important to note that even in these relatively wetter months, the amount of precipitation remains low.

The driest months in Winnipeg are the winter ones — January, February, March, December, as well as November. In each of these months, an average of only 1 mm of precipitation falls. Winter precipitation is predominantly represented by snow, given the average temperatures significantly below zero. The number of days with precipitation in these months ranges from 5 (in January and March) to 8 (in November). April and October are transitional months with 2 mm of precipitation and 8-9 wet days, when both rain and snow may be observed.

When planning a trip to Winnipeg, it is important to consider the significant seasonal weather fluctuations. The climate here is continental, with cold, snowy winters and warm, occasionally humid summers. The principle of layering in clothing will be your best friend at any time of the year, allowing you to adapt to temperature changes throughout the day. Do not forget comfortable walking shoes, as the city is conducive to walking.

In winter (from December to March, as well as in November and partly in April), very low temperatures are expected, often dropping significantly below zero. Be sure to bring very warm clothing: thermal underwear, fleece jumpers, a down jacket or parka designed for severe frosts, a hat, a scarf, warm gloves or mittens, and waterproof winter boots. Although there is little rainfall, snow is a common occurrence here. In the off-season (April-May and October-November), the weather can be unpredictable: from cool to moderately warm. You will need a mid-season jacket, sweaters, jeans or thick trousers, as well as a hat and gloves in case of a cold snap. A waterproof jacket or an umbrella will be useful, as the number of rainy days increases.

The summer months (from June to August, as well as warm May and September) bring warmth, sometimes heat, with average temperatures around +20°C and above. During this period, you will need light clothing: t-shirts, shorts, dresses, sandals. However, evenings can be cool, so a light jacket or sweater will come in handy. Given the increase in the number of rainy days and precipitation in the summer months, a compact umbrella or raincoat will be very appropriate. Sunscreen, a hat, and sunglasses are also necessary for protection from the sun on clear days.
