Manitoba has four different seasons – spring, summer, fall and winter. The temperatures can be very hot in the summer and very cold in the winter.
You must plan your activities and your clothing around the temperatures so that you and your family remain safe and healthy.
Before going out check the weather conditions on the radio, TV or computer. For seasonal and daily forecasts visit the Environment Canada Weather Office.
When you hear or read a weather report take note of the temperature, wind speed and in summer the ultraviolet (UV) index and in winter the windchill factor (a combined measure of air temperature and wind).
Winter is cold with lots of snow but Manitobans enjoy this time of year by participating in outdoor activities such as ice skating and skiing. You must dress warmly; extreme cold and wind are dangerous. If you are not used to the cold remember that in Manitoba all buildings, houses and apartments are heated.
