Destination Basics

Thunder Bay has short summers (typically less than 100 days) with moderate average highs in the low 20s C. Winter is the longest season here, on average lasting six months from November to May. Temperatures are cold and there is plenty of snow – perfect for skiing, snowboarding and snowmobiling. But remember, daylight during the winter months is limited here (around 8.5 hours a day), so take advantage of the outdoors early in the day. Spring and fall are also on the cooler side in Thunder Bay but the beautiful colours of the trees changing colour more than makes up for the temperature.
