Weather in Montgomery in December

Shoulder season. December is shoulder season in Montgomery — cheaper, quieter, and a genuine gamble. Highs average 15.1 °C, lows 3.5 °C, and rain falls on 10 days — nothing in the month is working against you.

December ranks 8 of 12 in Montgomery: past the worst of the year but short of October, which is the month to book if the dates are open.

The rain arrives in bursts — 5 of the 10 wet days are heavy ones. Mornings tend to hold; build the outdoor half of each day before lunch and keep the afternoon flexible. Pack for 15.1 °C days and 3.5 °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: 10 nights fall below freezing. Across the twenty years measured, the hottest December day reached 26.5 °C and the coldest night fell to -7.1 °C, and the wettest single day dropped 77 mm — roughly 55% of the month's rain in one day.

December is moderately variable: 35 mm in the driest year against 343 mm in the wettest, around an average of 139 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind is light at 5.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.

How December sits in the year

The month is on the way down: 5.1 °C cooler than November, with January dropping another 1.9 °C. The first week and the last are not the same trip.

Daylight in December

December sits at the dark end of Montgomery's year — 10 hours of daylight against 14.3 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

With no coast nearby, the year swings a fair way — 31.7 °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.

December in Montgomery versus nearby

If Montgomery is one option among several, the nearby comparison is worth making. Atlanta is close enough to be a coin toss — 2.1 °C cooler, 1 day more rain. Mobile is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: December is a compromise. October is 25 points better and is what Montgomery is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
