Weather in Prince George in May
Canada · 20-year averages, May
A good month. May works. It is not the peak, but nothing about it fights you. Highs average 16.1 °C, lows 4.2 °C, and rain falls on 13 days — nothing in the month is working against you.
May ranks 5 of 12 in Prince George: past the worst of the year but short of August, which is the month to book if the dates are open.
Rain on 13 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.1 °C days and 4.2 °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: 4 nights fall below freezing. Across the twenty years measured, the hottest May day reached 32.2 °C and the coldest night fell to -3.8 °C.
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 86 mm against 29 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 55 mm average is a reasonable planning figure, not a promise.
Wind is light at 0.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.
How May sits in the year
The month is on the way up: 7.6 °C warmer than April, and June adds another 3.5 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in May
15.9 hours of daylight, gaining 1.7 hours across the month. That is between Prince George's extremes of 17.1 and 7.4 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 34.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
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 Prince George versus nearby
If Prince George is one option among several, the nearby comparison is worth making. Jasper is the weaker option in May — 2.3 °C cooler, 3 days more rain. Whistler is the weaker option in May — 5.5 °C cooler, 2 days more rain.
So: May works, with August the better month by 16 points if the dates can move. If they cannot, nothing here should stop you booking.
