This could mean reduced amounts of rain and snowfall together with higher temperatures and lower home heating bills. The North West Territories including the Arctic islands and the Maritime provinces do not normally experience the effects of El Ni o. La Ni a usually means lower than normal temperatures from the west coast to Northwestern Ontario. On Average, temperatures are 1 to 2 degrees below normal across Canada. As well, snowfall is above normal from British Columbia to the St. Lawrence Valley.
Higher temperatures are most noticeable in southern British Columbia.
There is, however, much less snow in the southern half of British Columbia and slightly less snow elsewhere in the region. This is probably due to higher temperatures resulting in changes to the proportion of rain and snow. The difference in temperatures between La Ni a and normal conditions are much larger than the El Ni o anomalies. Temperatures are on average 1 degree colder in southern British Columbia and as much as 3 degrees cooler in Yukon. In terms of total precipitation , La Ni a winters tend to be slightly wetter in the interior, near normal along the coast, and much wetter in the southeast part of British Columbia.
