Overview of Constantine’s Winter Climate
Constantine’s winters bring mild daytime temperatures, cold nights, rainfall, and the occasional snow. The city’s elevation and inland spot really shape its seasonal weather, while the Mediterranean climate brings a mix of wet and dry spells.
Geographical Influences on Winter Weather
Constantine sits at about 770 meters (2,500 feet) above sea level, so winters here run cooler than Algeria’s coastal cities. The higher elevation lets cold air settle at night, often dropping temperatures close to or below freezing.
Snow isn’t frequent, but it does happen. You’ll usually get about six days of snowfall per year, mostly light, though a cold snap can bring more. In rare cases, temperatures have dropped as low as -10 °C (14 °F).
The city sits roughly 80 km (50 mi) from the Mediterranean coast, so it doesn’t get the full moderating effect of the sea. Inland winds and regional weather systems can bring sharp drops in temperature, especially in January and February.
Rain is much more common than snow. Winter months see the highest precipitation, with 50–60 mm of rain per month. That keeps the air more humid than the dry summer season.
Mediterranean Climate Characteristics
Constantine’s climate falls into the Mediterranean with hot summers (Csa) category, but winter shows the cooler, wetter side of this pattern. You’ll notice clear differences between day and night, with average daytime highs around 12–13 °C (54–55 °F) and nighttime lows near 2–3 °C (36–37 °F).
Humidity often stays high, ranging from 70% to 77%, which makes the air feel damp. This is especially noticeable during cloudy stretches, when sunshine drops to about 5–6 hours per day.
Rain falls on roughly 10–12 days per month in winter, so you get a mix of wet and partly cloudy days. Snow is possible, but most winter precipitation comes as rain, not snow.
Despite the chill, you still get a decent amount of daylight, with 10–11 hours per day in midwinter. This balance of rain, humidity, and a bit of sun defines Constantine’s winter climate.

Record Cold Events and Extremes
Constantine’s winters aren’t severe by regional standards, but extreme cold does hit sometimes. The city’s elevation at 1,880 feet (573 m) makes it more prone to sharp temperature drops than coastal areas.
Once in a while, cold waves push temperatures far below the averages. For example, -10°C (14°F) was recorded in February 1999. Other years have seen lows of -5°C (23°F).
Snowfall happens, but it’s pretty limited. On average, you’ll see about six days of snow per year, usually light and not sticking around. These events show just how variable the winter can be, even if it’s usually moderate.
Monthly Temperature Variations
Constantine’s winter temperatures stay stable compared to other seasons. December and February share similar averages, while January is a bit cooler.
The coldest stretch usually lands in mid-January, with daily highs near 54°F (12°C) and lows at 38°F (3°C).
Unlike spring or fall, winter doesn’t swing wildly between warm and cold. Instead, you get a steady pattern of cool afternoons and chilly nights.
This steadiness actually makes planning outdoor activities a bit easier. You can count on cool but manageable conditions, with only the occasional interruption from a colder air mass.

Snow in Constantine is less common than rain, but it does show up. On average, you’ll see about six days of snowfall per year, most often in January or February.
Accumulations are usually light, though heavier snowfalls can hit during a cold spell. Past records show temperatures dropping to -10°C (14°F), which allowed for more intense snow events.
Snow rarely lingers long in the city itself, since daytime highs often reach the mid‑40s to mid‑50s °F. Higher elevations nearby can hold snow longer, which might affect travel routes outside the city.
Monthly Precipitation Distribution
Winter precipitation doesn’t spread evenly across the months. December and January tend to be the wettest, with daily rain chances around 21–29%. February stays wet but drops off a bit as spring nears.
- December: ~21% chance of rain on a given day

Humidity and Wind Conditions in Winter
During winter in Constantine, you’ll notice higher humidity compared to the dry summer, and plenty of cold winds. These two factors combine to shape how cold the season feels and how comfortable it is to be outside.
Average Humidity Levels
Humidity in Constantine rises in winter, thanks to more rain and cooler air. You can expect average levels between 65% and 75%, which feels much damper than the summer, when values often dip below 45%.
This extra moisture brings damp mornings, fog, and a chill that sometimes feels sharper than the numbers suggest. Even when it’s above freezing, the humidity can make the air feel raw.
Rainfall averages between 15–20 mm per month in December and January, keeping things moist. Snow isn’t frequent, but it does show up a few days each winter, adding to that damp, chilly feeling.
If you’re heading outside, breathable but water-resistant clothing helps keep you comfortable in Constantine’s humid winter.
Prevailing Winter Winds
Constantine sits on a plateau, leaving it exposed to stronger winds in winter. The most common winds blow from the north and northwest, bringing in cold air from the Mediterranean and higher inland elevations.
Average wind speeds run from 10–15 km/h (6–9 mph), but gusts can spike higher during passing weather systems. These winds often come with rain or snow showers, making things feel harsher.
The city’s elevation means wind is more noticeable than in coastal areas. Streets that cut through open valleys or cross bridges can feel extra gusty.
If you’re visiting, expect breezy days and be ready for sudden shifts in comfort when moving from sheltered spots to open areas.
Wind Chill and Perceived Temperatures
Wind chill really changes how you experience Constantine’s winter. Even if the thermometer says 5°C (41°F), a steady wind of 15 km/h can make it feel closer to 0°C (32°F).
This effect is strongest at night and early morning, when lows already dip near 3°C (37°F). Combined with humidity, the chill can feel sharper than you’d expect.
Plan on layering, with jackets that block wind and insulated linings. Gloves, scarves, and hats help cut down on heat loss from wind exposure.
By keeping wind chill in mind, you’ll be better prepared for sightseeing outside, especially on the city’s exposed bridges and viewpoints.
Sunshine and Daylight Hours
Winter in Constantine brings shorter days and less sunshine than summer. You get limited daylight and reduced sun exposure, which affects outdoor activities and the season’s overall mood.
Average Daily Sunshine
During winter, you’ll see much less sunshine than in summer. In January, the city averages about 214 hours of sunshine for the month, which comes out to roughly 7 hours per day.
By February, this climbs to around 271 hours, or close to 9.5 hours daily. Cloud cover is more common, so actual bright sun may feel rare. Rain and cool air also cut down on clear-sky days.
Still, Constantine gets more winter sunshine than a lot of European cities at this latitude.
Here’s a quick look at monthly sunshine for early winter:
| Month | Total Sunshine Hours | Avg. Daily Sunshine |
|---|---|---|
| January | ~214 hrs | ~7 hrs |
| February | ~271 hrs | ~9.5 hrs |
This steady increase means you’ll notice longer, brighter days as winter moves along.
Daylight Duration Changes
Daylight hours in Constantine shift gradually during winter. In December, days are shortest, with the sun rising late and setting early. You get about 9.5 to 10 hours of daylight in mid-December.
By January, daylight picks up a bit, and by late February you’ll have closer to 11 hours of daylight. The change is steady, so each week brings a few extra minutes of usable light.
These shifts matter if you’re planning sightseeing, outdoor work, or travel. Shorter days in early winter mean you should start activities earlier. Late winter gives you a bit more flexibility.
Longer daylight also helps warm up afternoons, making late winter feel a bit more inviting for spending time outside.
Winter Weather Impacts and Travel Tips
Winter in Constantine usually means cooler temperatures, regular rainfall, and the occasional snowstorm. Some days feel mild, but sudden cold snaps can pop up and mess with your daily plans or travel.
Seasonal Weather Hazards
Winter lows often dip close to freezing, and you’ll probably wake up to frost on your car more than once. Sometimes, the temperature drops below -5 °C, and, in rare cases, it can even hit -10 °C.
You might only see a few days of snowfall each year, but icy roads and slick sidewalks still create headaches for getting around.
Rain falls more often in winter than in summer. January and December usually bring about 60 mm of precipitation each, spread out over 10 to 12 days.
When it rains a lot, rural roads get muddy and pretty tough to drive on.
Humidity hangs around above 70% most of the time, making the air feel colder than you’d expect. Strong winds sometimes blow through, especially in open spots, and that just adds to the chill.
Fog or heavy rain can roll in and cut visibility, so don’t be surprised if your ride gets delayed now and then.
Recommendations for Visitors
Bring layered clothing so you can handle whatever the weather throws at you. Toss in a waterproof jacket and some sturdy shoes—those work for rain and even a bit of snow.
Don’t forget your gloves, hats, and scarves, especially if you’re out at night. The cold can sneak up on you.
Keep in mind, you’ll get shorter daylight hours here. In midwinter, you might only have about 10 hours of daylight, so try to start outdoor plans earlier than usual.
If you think you’ll be out after dark, a flashlight really comes in handy.
If you’re driving, watch out for slick or icy roads. Renting a car with decent tires helps, and always check the local forecast before heading out of town.
Public transport usually keeps running, though you might run into minor delays when the weather gets rough.
Inside, lots of buildings use space heaters instead of central heating. If you want to stay warm, look for accommodations that actually have reliable heating.
