<Li> Winter about − 9 ° C (16 ° F) to 0 ° C (32 ° F) </Li> <P> Due to the ocean's moderating effect, Nova Scotia, on average, is the warmest of the provinces in Canada, owing primarily to the milder winter temperatures experienced in Nova Scotia compared to the rest of Canada . </P> <P> All of Nova Scotia has precipitation well distributed around the year, with a slight summer maximum in some northern / interior areas, but a slight fall to early winter (October to January) maximum in southern and coastal areas, where July or August is the driest month on average . Fall and winter storms, arriving in or near Nova Scotia from the U.S. Northeastern and New England states (called "nor'easters" in the US), often attain tremendous intensity across coastal areas, resulting in high winds, heavy rain, ice or snow and sometimes all of the above in a single storm . Average annual precipitation changes from 140 centimetres (55 in) in the south with its intense cold - season storm activity, to 100 centimetres (40 in) elsewhere . In the northeast, Sydney is an especially wet area, with an average annual precipitation of nearly 60 inches, with a noticeable fall to early winter (October to January) concentration, and December the wettest month on average . Nova Scotia is also very foggy in places, with Halifax averaging 196 foggy days per year and Yarmouth 191 . </P> <P> Because Nova Scotia juts out into the Atlantic, it is prone to intense cold - season storms ("nor'easters" - primarily November to March) arriving from the Northeastern United States, and occasional tropical storms and hurricanes in late summer and autumn . However due to the relatively cooler waters off the coast of Nova Scotia, tropical storms are usually weak by the time they reach Nova Scotia . Even where a storm retains much of its strength, as with Hurricane Arthur, it is most often extratropical by the time it makes landfall on Nova Scotia . </P>
