Weather in Lethbridge in November

The month to avoid. November is the month most people should skip in Lethbridge. Highs sit at 4.6 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

November ranks 9 of 12 in Lethbridge: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 8 days, 0 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 4.6 °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: 22 nights drop below freezing, so anything left outside stays frozen. Across the twenty years measured, the hottest November day reached 18.9 °C and the coldest night fell to -27.2 °C, and the wettest single day dropped 32 mm — roughly 94% of the month's rain in one day.

November is moderately variable: 12 mm in the driest year against 117 mm in the wettest, around an average of 34 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind is light at 12 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, which at 4.6 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How November sits in the year

The month is on the way down: 8 °C cooler than October, with December dropping another 5.9 °C. The first week and the last are not the same trip.

Daylight in November

9.1 hours of daylight, losing 1.4 hours across the month. That is between Lethbridge's extremes of 16.3 and 8.2 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 37 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. At 907 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

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.

November in Lethbridge versus nearby

If Lethbridge is one option among several, the nearby comparison is worth making. Calgary is close enough to be a coin toss — within a degree on temperature, 2 days less rain. Banff is the weaker option in November — 5.6 °C cooler, 8 days more rain.

So: November is a compromise. August is 56 points better and is what Lethbridge is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
