If you’re planning a trip to Constantine during the holidays, get ready for crisp winter air, shorter days, and the possibility of rain. Around Christmas, you’ll see daytime temperatures close to 13°C (mid-50s °F) and nighttime lows around 3°C (upper 30s °F), often with damp conditions.
Snow doesn’t happen often, but it’s not out of the question. The evenings can get pretty chilly, so you’ll want to pack some warm clothes.
December usually brings more rainfall than the dry summer, so the city feels fresher but also colder and wetter. You won’t get much sunshine—daylight lasts under 10 hours, which affects how long you can wander Constantine’s bridges, markets, and old streets.
If you know what to expect, you can enjoy the city without any big surprises. Rainfall patterns, daylight hours, and other details of Constantine’s winter climate all play into how you’ll plan your activities and what you’ll bring.
Typical Christmas Weather in Constantine
Late December brings cool days, chilly nights, and more rain than summer. Days stay mild, evenings get colder, and you’ll notice the air feels damper and cloudier.
Average Daytime Temperature
In December, average daytime temperatures in Constantine hover around 14 °C (57 °F). This is definitely one of the colder months.
Most days feel comfortable enough for a light jacket or sweater, especially early in the afternoon if the sun comes out. Still, the air stays crisp, and you never really get that spring or autumn warmth.
Clouds show up more often, which means less sunshine. The sun doesn’t warm things up much, so even midday can feel chillier than you’d expect. If you’re heading outside, wear layers you can peel off or add as needed.
Nighttime Temperature Range
At night, Constantine cools down a lot. The average low in December drops to about 3 °C (37 °F), and some nights get close to freezing.
You’ll need to be ready for cold evenings and mornings. A heavier coat comes in handy if you’re out after sunset. Indoors, most people use heating to stay comfortable.
The difference between day and night temperatures really stands out. Afternoons might feel mild, but it gets cold quickly once the sun goes down. If you expect to be out at night, bring extra layers.
Weather Patterns During December
December is a wetter month in Constantine. Average precipitation is around 63 mm, making it the wettest time of year. Rain usually falls as short, steady showers, not long storms.
Humidity climbs to about 79%, so the air feels even colder. Cloudy skies are common, and you get fewer hours of sunshine than in summer.
Winds blow at a moderate 17 km/h, and they can make things feel colder. Visibility usually stays decent, but you might see some mist or light fog in the mornings. All these factors combine to give Constantine a damp, wintry vibe during Christmas.
Rainfall and Humidity Levels
December brings cooler weather, moderate rain, and higher humidity than summer. Days tend to be wetter than in autumn, but you won’t see the heavy downpours of early spring. Humidity goes up as temperatures drop, making the Christmas air feel damp and chilly.
Average Precipitation in December
December sees about 18 mm (0.7 inches) of rain, spread out over several days. It’s not a huge amount, but it’s definitely wetter than July or August, when it rarely rains.
You’ll mostly get light to moderate showers, not all-day rain. Snow can happen, but it’s rare—just a dusting some years. Rain is more likely in the evenings and overnight, when it’s colder.
Compared to spring, December rainfall happens less often and isn’t as heavy. March and April usually get twice as much. December is more of a transition, with rain showing up but not dominating.
If you’re traveling, pack a light waterproof jacket. Roads and sidewalks can get slippery after rain, so sturdy shoes are a good idea.
Humidity Trends Around Christmas
Humidity in Constantine goes up in winter, averaging 70–75% in December. That’s a big jump from summer, when it can drop to 40%. Higher humidity makes the air feel colder than the thermometer says.
Mornings during Christmas often feel the dampest. Fog and mist pop up, especially in valleys or near the city’s cliffs. Drivers might notice reduced visibility and slower morning commutes.
Inside, higher humidity can make heating seem less effective. Sometimes you’ll feel a chill even if it’s just above freezing. Layering up helps you stay comfortable as you move between inside and outside.
Humidity and moderate rain together create Constantine’s cool, moist holiday atmosphere.
Wind Conditions in December
Winds in Constantine during December usually stay light to moderate, but sometimes they pick up when the weather changes. Expect cool breezes that make winter nights feel even colder, and sometimes stronger gusts on unsettled days.
Average Wind Speed During Christmas
In December, average wind speed sits between 10 and 15 km/h (6 to 9 mph). That’s pretty mild, so most days you can walk outside without much trouble. Still, when it’s near 5°C (41°F) at night, even a light wind feels chilly.
During the day, breezes usually stay steady and predictable. Constantine doesn’t get the strong sea winds like Algeria’s coast. The city’s inland spot and higher elevation keep wind speeds moderate.
You’ll probably notice calmer air early in the morning and late at night. Midday might bring a bit more breeze, especially if clouds and light rain roll in. These patterns don’t change much from year to year, so December wind is pretty reliable.
Notable Wind Patterns
December winds mostly come from the north and northwest. These bring cold air across the Mediterranean and make things feel even chillier, especially in open spots around the city.
Sometimes, southerly winds show up when low-pressure systems pass through. They don’t happen as often, but they can bring slightly warmer air from inland.
Gusts over 20 km/h (12 mph) don’t happen a lot, but they’re possible—usually with brief rain showers. If you’re heading outside, especially to higher ground or bridges, you’ll probably notice the wind more in those areas.
Most visitors find December winds in Constantine noticeable, but they usually don’t cause problems.
Sunshine and Daylight Hours
In late December, you’ll get shorter days and weaker sunlight than in summer. Sunshine is limited, but there’s still enough daylight for sightseeing and outdoor plans if you time things right.
Typical Daily Sunshine
Around Christmas, Constantine gets about 214–220 hours of sunshine for the month, or 7 hours per day. That’s a lot less than summer, when you might get more than 13 hours each day.
The winter sun sits lower in the sky, so the light feels softer and less harsh. Shadows stretch longer, especially in the late afternoon. December also brings more cloud cover, which means fewer bright, clear days.
Even with cooler air, the midday sun can feel nice if the sky’s clear. The best time for steady sunlight is usually from 10:00 a.m. to 3:00 p.m. That’s when you’ll find the most comfortable conditions outside.
Length of Daylight Around Christmas
Daylight in Constantine is shortest in December, with about 9 to 9.5 hours of light per day. The sun rises around 7:30 a.m. and sets near 5:00 p.m., depending on the date.
This limited daylight means you’ll need to plan your activities. Morning and early afternoon work best for sightseeing or outdoor trips. Evenings come quickly, and temperatures drop right after sunset.
Short winter days really stand out compared to summer, when the sun’s up for 14 hours. In December, you’ll probably switch to earlier nights, maybe spending more time indoors, enjoying meals, or checking out Constantine’s cultural spots before dark.
Comparing Christmas Weather to Other Months
December in Constantine brings cool days, cold nights, and more rain than the dry summer. Temperatures are near the lowest for the year, and daylight is shorter than usual. These conditions feel pretty different from the hot summer or the wetter parts of winter.
How December Differs From Other Winter Months
In December, daytime highs hit about 56°F (13°C), while nights drop to 40°F (4°C). It’s a bit warmer than January, which is the coldest month—highs near 54°F (12°C) and lows around 38°F (3°C).
Rainfall in December averages 2.6 inches, making it one of the wettest months. January gets about the same, but February usually drops to 2.2 inches. Snow can fall in December, but it’s more likely in January when cold spells are stronger.
Clouds cover the sky a lot in December—mostly cloudy or overcast about half the time. February starts to clear up as spring gets closer.
Seasonal Changes Leading Up to Christmas
The weeks before Christmas bring a steady drop in temperatures from autumn. October highs reach 75°F (24°C), November falls to 64°F (18°C), and by December, highs settle in the mid-50s.
Rain increases fast, too. October averages 1.7 inches, November goes up to 2.2 inches, and December peaks at 2.6 inches. Late fall and early winter bring more frequent rain than the dry summer.
Daylight shortens as well. November offers about 10.2 hours of daylight, while December averages only 9.7 hours, the least all year. This, combined with cooler temperatures, gives Constantine a real winter feeling by Christmas.
Travel and Packing Tips for Christmas in Constantine
Temperatures in Constantine during late December stay cool, with chilly nights, damp air, and more rain than in summer. You’ll want to prepare for moderate days, cold evenings, and the possibility of wet weather.
Clothing Recommendations
Daytime highs in December usually reach 14 °C (57 °F), while nighttime lows often drop near 3 °C (37 °F). You’ll need layers that you can adjust as the weather changes.
Pack a warm jacket—water-resistant is best, since December is one of the wetter months. A mid-weight fleece or sweater under your coat adds warmth.
Bring long pants in thicker fabrics like denim or wool blends. Skip the summer clothes. For evenings, gloves and a scarf make a difference, especially if you’re outside after dark.
Footwear should be sturdy and waterproof. Rain can make the streets slick, so shoes with good grip help. An umbrella or a small rain poncho is practical, too.
Weather-Related Travel Advice
December usually brings over 60 mm of rainfall, so it’s honestly the wettest month out there. If you’re heading between cities or thinking about a day trip, just plan for possible delays and give yourself some wiggle room.
You’ll generally get fair visibility, but those damp mornings might surprise you with a bit of fog. When you pick up your rental car, double-check the headlights and wipers—nobody wants to mess with that in the rain.
Public transport keeps running, but colder evenings can make waiting outdoors a bit uncomfortable. I’d toss a small thermos or water bottle in your bag, since indoor heating in public spaces isn’t always great.
If you’re wandering around historic sites, be ready for uneven stone streets that get pretty slick after it rains. Non-slip shoes and taking it slow will save you a lot of trouble.
