Weather in Sherbrooke in March

The month to avoid. March is the month most people should skip in Sherbrooke. Highs sit at 1 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

March ranks 11 of 12 — near the bottom of Sherbrooke's year. September is the month that works, and the swing between the two is 63 points, which is a different holiday rather than a slightly better one.

This is persistent light rain rather than storms: 14 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Layers, and a genuinely waterproof outer — at 1 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 28 nights drop below freezing, so anything left outside stays frozen. Across the twenty years measured, the hottest March day reached 22.4 °C and the coldest night fell to -32.2 °C, and the wettest single day dropped 27 mm — roughly 37% of the month's rain in one day.

March is one of the reliable ones — rainfall has stayed between 44 mm and 106 mm across all twenty years, a narrow enough band that the 73 mm average is something you can plan against rather than merely quote.

Wind is light at 3.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 90%, which at 1 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How March sits in the year

The month is on the way up: 5.5 °C warmer than February, and April adds another 8.5 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

11.8 hours of daylight, gaining 1.6 hours across the month. That is between Sherbrooke's extremes of 15.6 and 8.8 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 39.7 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

March in Sherbrooke versus nearby

If Sherbrooke is one option among several, the nearby comparison is worth making. Montréal is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Québec is close enough to be a coin toss — 2.2 °C cooler, 2 days less rain.

So: March is a compromise. September is 60 points better and is what Sherbrooke is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
