Winter in the Halifax Regional Municipality

When winter arrives in Nova Scotia, planning for outdoor activities can be more of a challenge than you might expect. In most of the country, winter means cold and snow, and that can be true of the HRM, but the problem is ... not always, and not necessarily everywhere.

Don't be confused, the explanation is quite simple, even if the implications are not. Nova Scotian weather is affected both by the moderating influence of the Atlantic Ocean and air currents that regularly push relatively warm air up the Atlantic coastline of North America from the Caribbean. As a result, there is a higher degree of variability in temperatures than normal in other parts of the continent, particularly along the coastline.

Snowfall amounts vary tremendously within the HRM. Annual accumulations at Dollar Lake Provincial Park are more than 100cm higher than those in Halifax. In addition, coastal winds scour headlands, keeping them nearly bare, while the continuous freeze/thaw/freeze cycle means that ground conditions are often icy.

Consequently, snowshoeing is the recommended mode of travel when visiting coastal parks such as Taylor Head. Although there are areas, sheltered from the wind, where the snow can be deep, usually it is fairly shallow and slippery. The metal grips of snowshoes are ideal in these circumstances. Cross-country skiers should head inland, to Oakfield and Dollar Lake parks. Here conditions are often superb, even if the tracks are not groomed.

In any case, whether visiting coastline or inland, be certain to check the weather forecast before you venture outdoors. Conditions can change rapidly, and it is vital for your safety that you be prepared for whatever a Nova Scotia winter can throw at you. Enjoy!
