An average November across Canada<\/a> is no picnic as autumn begins to fade against winter’s steady advances.<\/p>\n

But this month won’t follow the typical script.<\/p>\n

Several historic events may throw a wrench in the pattern, including an unprecedented breakdown in the polar vortex<\/a> and an intense El Ni\u00f1o flexing its influence.<\/p>\n

DON’T MISS: Canada’s polar vortex wild card is waking up much earlier than expected<\/a><\/p>\n

Powerful El Ni\u00f1o continues to dominate<\/p>\n

We’re in the midst of an unprecedented El Ni\u00f1o<\/a> right now.<\/p>\n

\"November<\/p>\n

November 2026 Super El Ni\u00f1o<\/p>\n

Sea surface temperature anomalies running about as high as they’ve ever been observed in key regions of the eastern Pacific Ocean.<\/p>\n

These historically warm waters are significantly influencing weather patterns<\/a> across North America.<\/p>\n

\"November<\/p>\n

November 2026 Temperature Pattern<\/p>\n

We saw above-seasonal conditions across most of Canada during October as a whole, with the warmest conditions parked over the centre of the country.<\/p>\n

Temperatures will continue to run warmer-than-normal for a majority of the country throughout November, although near-seasonal conditions are expected in Atlantic Canada and southern British Columbia.<\/p>\n

One potential hiccup in the pattern will originate thousands of kilometres across the Pacific Ocean.<\/p>\n

\"November<\/p>\n

November 2026 Recurving Typhoon Effect<\/p>\n

Recurving typhoons can disrupt the pattern by disrupting the jet stream, allowing warmth to build over Western Canada while folks back east deal with a brief dose of colder air.<\/p>\n

Watching a historic polar vortex breakdown<\/p>\n

Forecasters are also closely monitoring an unprecedented breakdown in the polar vortex across the far northern latitudes, which is occurring three weeks earlier in the season than ever recorded in the past.<\/p>\n

\"November<\/p>\n

November 2026 Split Polar Vortex<\/p>\n

The polar vortex is a wind circulation that acts like a moat<\/a>, keeping the season’s coldest air locked near the poles. Frigid air can spill southward when this wind circulation breaks down.<\/p>\n

Where the heart of the cold air travels after the polar vortex breaks down remains an open question. Canada could very well bear the brunt of this event–but it could just as easily slide toward Siberia instead. This will become clearer later in November.<\/p>\n

A November reality check<\/p>\n

November has a reputation for unpleasant weather across Canada as the warmth of autumn gives way to more frequent tastes of early winter weather<\/a>.<\/p>\n

\"November<\/p>\n

November Climate Normal Highs Canada<\/p>\n

Average daytime high temperatures quickly fall between the beginning and end of November. Most communities away from the coasts are on track for a 5-7\u00b0C drop in average highs between Nov. 1 and Nov. 30.<\/p>\n

Keep this decline in mind when above-seasonal temperatures are in the forecast. A warmer-than-normal day in November is still chilly enough to require a jacket across most of Canada.<\/p>\n
