Weather in Saguenay in May

A good month. May works. It is not the peak, but nothing about it fights you. Highs average 16.2 °C, lows 4.7 °C, and rain falls on 13 days — nothing in the month is working against you.

May ranks 5 of 12 in Saguenay: past the worst of the year but short of June, which is the month to book if the dates are open.

Rain on 13 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.2 °C days and 4.7 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 3 nights fall below freezing. Across the twenty years measured, the hottest May day reached 29.7 °C and the coldest night fell to -6 °C, and the wettest single day dropped 32 mm — roughly 40% of the month's rain in one day.

May is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest May on record still delivered 139 mm against 27 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 81 mm average is a reasonable planning figure, not a promise.

Wind is light at 6.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How May sits in the year

The month is on the way up: 9.9 °C warmer than April, and June adds another 5.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in May

15.2 hours of daylight, gaining 1.3 hours across the month. That is between Saguenay's extremes of 16.1 and 8.4 hours, so days are long enough not to constrain the plan.

An inland climate

Saguenay has no sea to moderate it, and it shows: 45.1 °C separates the hottest afternoon of the year from the coldest night. That is a genuinely continental range, and it means summer and winter here are barely the same place.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

May in Saguenay versus nearby

If Saguenay is one option among several, the nearby comparison is worth making. Québec is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Sherbrooke is close enough to be a coin toss — within a degree on temperature, 4 days more rain.

So: May works, with June the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
