Montreal could see its first 18°C of the year today — potentially the warmest March 9 in over 20 years

Montrealers rejoice: the city may reach the first 18°C of the year today.

After a hard winter that found Quebec one of the coldest places on the planet—literally—there’s cause for celebration.

But enjoy it while you can.

According to a report by MeteoMedia, all signs suggest we could even experience the warmest March 9 since 2002, when the temperature hit 16.8°C in Montreal.

A special weather statement issued this morning warns of a potentially critical freezing rain situation expected on Wednesday and Thursday (but more on that later).

What is the warmest March on record in Montreal?

The last time temperatures rose above 15°C in the city was October 20, 2025, and temperatures could climb to as high as 18°C in southern Quebec today.

By this afternoon, thermometers are expected to reach at least 15°C in Sherbrooke and Montreal.

The record highs for March 9 date back to 2000 in Ottawa and Montreal, with temperatures of 19.2°C and 17.4°C respectively. 

Is there a freezing rain warning for Montreal?

Overnight from Sunday to Monday, temperatures also rose above 0°C across both southern and central Quebec, kicking off the week on a pleasant note.

Make the most of this mild break by taking a long walk in the sunshine — because the rest of the week is expected to be much less forgiving.

A weather system could hit Quebec in the coming days, bringing up to 30 mm of freezing rain to southern Quebec.

Significant snowfall is also possible north of the St. Lawrence Valley.
