Fall in Tlemcen, Algeria brings a noticeable shift in weather that shapes daily routines and travel plans. You’ll get warm early autumn days that slowly cool off, especially in the evenings as winter approaches.
This change makes the city’s fall climate pretty comfortable and varied. There’s this nice balance between lingering summer heat and the first hints of colder months creeping in.
As temperatures drop, you start to notice shorter days, more clouds, and a bit more rain. These shifts give outdoor activities, cultural visits, and city exploring a different vibe than the blazing summers or chilly, windy winters.
If you get a handle on these patterns, you can plan your days with a bit more confidence. Whether you’re wandering through historic sites or just figuring out what to wear, fall in Tlemcen isn’t extreme, but it’s definitely dynamic.
Typical Fall Temperatures in Tlemcen
During fall, Tlemcen’s temperatures cool off steadily from the summer’s heat toward a wintery chill. You’ll feel warm afternoons in September, but by late November, the days turn mild or even a little chilly. Nights cool down faster, so the difference between day and night stands out.
Daily High and Low Temperature Trends
At the beginning of fall, daily highs usually hit around 30°C (86°F). By late November, highs drop closer to 15°C (59°F).
Early fall almost feels like a late summer, but by the end, it’s much more like winter.
Nighttime lows follow the same pattern. In September, you’ll see nights averaging about 17°C (62°F), but by late November, they dip to 5°C (41°F) or so.
Cooler nights arrive before the days really cool off, so that day-night swing grows as fall goes on.
The gap between highs and lows can get pretty wide, especially in October and November. You might enjoy a warm afternoon, then suddenly need a jacket by sunset. Layering really comes in handy.
Monthly Temperature Averages
Monthly averages make it easy to spot the shift in climate.
| Month | Avg. High | Avg. Low | Avg. Temp |
|---|---|---|---|
| September | 28°C (82°F) | 16°C (61°F) | ~22°C (72°F) |
| October | 23°C (73°F) | 12°C (54°F) | ~18°C (64°F) |
| November | 18°C (64°F) | 7°C (45°F) | ~13°C (55°F) |
You can see a cooling trend right away. September stays warm, October feels mild and pleasant, and November brings a real chill. By late fall, it’s basically early winter.
This pattern is typical for a Mediterranean climate at Tlemcen’s elevation. Seasonal changes here are sharper than on the coast.
Temperature Extremes and Records
Averages tell most of the story, but extremes do happen. Early fall highs sometimes spike above 33°C (92°F) during a hot spell. By late fall, nighttime lows can drop below 2°C (36°F), though it’s rare to see freezing before December.
The hottest days usually hit in early August, with highs around 32°C (89°F). The coldest stretch comes in mid-January, when highs reach only 13°C (55°F) and lows hover near 2°C (36°F).
Fall doesn’t bring those extremes often, but you can get sharp swings. It’s smart to prep for both mild afternoons and chilly evenings, especially if you’re outside a lot.
Rainfall and Precipitation Patterns
Rainfall in Tlemcen goes up as fall moves along. Early September brings light precipitation, but by late November, both the rainfall and the number of rainy days really pick up.
Average Rainfall by Month
September stays pretty dry, with about 0.5 inches (12–13 mm) of rain over the month. Most days are dry and clear.
By October, you’ll notice more showers and about 1.2 inches (30 mm) of rain. The middle and end of the month see the most.
November is the wettest, with averages hitting 1.9 inches (48 mm) and peaking around 2.0 inches (50 mm) in mid-November. Late fall is a lot wetter than early fall.
| Month | Avg Rainfall (inches) | Avg Rainfall (mm) |
|---|---|---|
| September | 0.5 | 12–13 |
| October | 1.2 | 30 |
| November | 1.9 | 48 |
Chance of Rainy Days
The odds of getting a rainy day go up through fall. In early September, only about 8% of days bring measurable rain, so you’re mostly looking at dry, clear skies.
By October, the chance jumps to about 15%. You’ll get occasional wet days, but showers are usually brief.
In November, the odds hit around 20%. It’s not a lot compared to rainier places, but it’s a real shift. Most rain falls as light or moderate showers, not heavy downpours.
Seasonal Changes in Precipitation
Fall in Tlemcen shows a sharp upward trend in both rainfall and rainy days. The move from dry summer to wetter autumn is gradual, but you’ll definitely notice it.
Early fall brings lots of clear skies. As weeks pass, clouds build up, and rain becomes more frequent.
By late November, things look and feel way different than in September. Temperatures are cooler, days are shorter, and rainfall is about four times higher than at the start of the season.
Sunshine and Daylight Hours
Autumn in Tlemcen brings steady changes in sunshine and daylight. You’ll see shorter days, less direct sunlight, and more cloud cover than in summer.
These changes affect how much light you get outdoors and can shift your daily plans or travel routines.
Average Sunshine Hours
In early autumn, expect about 9 to 10 hours of sunshine per day. That’s still pretty bright.
By November, you’re down to about 7 to 8 hours daily. The drop is gradual, so September feels much sunnier than late autumn.
Sunshine hours are still good for sightseeing or outdoor fun, but you’ll want to plan for less strong light as fall goes on.
Here’s a quick look at average sunshine:
| Month | Avg. Sunshine Hours/Day |
|---|---|
| September | ~9.5–10 hours |
| October | ~8–9 hours |
| November | ~7–8 hours |
That downward trend is normal for Mediterranean climates in the fall.
Daylight Duration Changes
Daylight hours shrink fast in fall. In September, you get about 12.4 hours of daylight, but by November, it’s down to 10.3 hours.
Your days feel a lot shorter by late autumn. If you want to get outside, start earlier to catch the light.
- September: ~12.4 hours
- October: ~11.3 hours
- November: ~10.3 hours
Losing daylight is one of the biggest seasonal changes. If you love sightseeing or hiking, you’ll need to tweak your schedule as evenings arrive sooner.
Cloud Cover and Sun Visibility
Clouds build up during fall, and the sky isn’t as clear as in summer. In September, you’ll often see about 11–20% cloud cover. By November, it goes up to 30%, which can block some sun.
It’s not a gloomy season, though. You still get plenty of bright days, but there are more partly cloudy stretches.
The extra clouds show up alongside more rain in late autumn. So, sunshine hours can be hit or miss, even though there’s still daylight. Expect a mix of sun and clouds, especially in October and November.
Wind and Atmospheric Conditions
During fall in Tlemcen, you’ll feel more wind and notice shifts in direction that change the day-to-day weather. These changes affect how cool or dry the air feels and can shape outdoor comfort and travel plans.
Typical Wind Speed in Fall
Wind speeds pick up through the fall months. Early September brings averages around 7.4 miles per hour (mph), but by late November, speeds climb to about 9.7 mph.
This gradual rise makes the air feel cooler, especially in the evenings.
Compared to summer’s calm, fall’s breezes stand out more. That matters if you’re planning outdoor activities, since wind can make it feel colder than the thermometer says.
Fall winds rarely get extreme, but the steady increase is enough to notice. Light jackets or windbreakers help, especially later in the season.
By November, you can expect moderate winds. They’re not disruptive, but if you’re out in open spaces or spending a lot of time outdoors, you’ll feel the difference.
Prevailing Wind Directions
As fall moves on, the wind direction changes. Early September brings winds from the north, which cool the air.
By mid-September and through November, the flow shifts to the west.
Westerly winds pull in moisture from the Mediterranean, which helps explain the rise in rainfall as fall goes on.
If you’re visiting, early fall feels drier and clearer, while late fall can get cloudier and a bit damp. This shift in direction really changes how the weather feels month to month.
If you’re in the city or exploring the countryside, open landscapes get more of this wind. Sheltered spots in town or valleys feel less breezy, but higher ground around Tlemcen gets the full effect.
Humidity, Dew Point, and Comfort Levels
In Tlemcen, how the air feels often depends more on moisture than on temperature. Humidity and dew point both shape comfort, especially when warm days turn into cool nights.
Average Humidity in Fall
In fall, you’ll find moderate to high humidity levels, especially in the mornings. At night, relative humidity often climbs above 70% as temperatures drop, sometimes causing light fog in valleys or shady spots.
By mid-afternoon, humidity usually drops as the air warms up. During the day, it’s common to see readings closer to 40–50%.
This daily swing means mornings can feel damp or heavy, but afternoons are more comfortable, even if it’s warmer. If you’re sensitive to humidity, keep in mind that mornings may feel cooler but stickier, while afternoons are drier.
Typical daily pattern in fall:
- Morning: 70–85% relative humidity
- Afternoon: 40–55% relative humidity
- Evening: 60–75% relative humidity
Dew Point Trends
The dew point gives a much clearer sense of comfort than relative humidity ever does. In Tlemcen during fall, dew points usually hover between 10°C and 15°C (50°F–59°F). That range feels pretty mild—not really oppressive—but sometimes, when it creeps up at night, the air can feel a bit damp.
Dew point barely shifts as the hours pass. Say you wake up to a dew point of 12°C, you’ll probably see almost the same number by afternoon, even if the temperature climbs.
This kind of stability makes dew point a solid way to guess how the air will actually feel. When the dew point dips below 10°C (50°F), the air feels crisp and dry. But once it climbs above 15°C (59°F), things get a bit muggy, especially if you’re indoors.
If you’re planning outdoor activities, checking the dew point can help you judge comfort way better than just looking at humidity percentages. It’s handy for figuring out the best times to hike, sightsee, or grab a meal outside.
Geographical Influences on Tlemcen’s Fall Weather
Tlemcen sits up in northwestern Algeria, where higher elevation mixes with a Mediterranean vibe. These two factors really shape the city’s cooler nights, mild afternoons, and the way rain comes and goes during fall.
Elevation and Its Impact
Tlemcen stands at about 2,661 feet (811 meters) above sea level. This elevation definitely helps keep temperatures cooler than what you’d find in Algeria’s coastal or desert areas.
In fall, you’ll notice the nights and mornings get pretty chilly, with lows often dropping into the low 40s °F (around 5–7°C). Daytime highs usually land somewhere in the 60s and 70s °F (15–24°C). The thinner mountain air lets the temperature fall quickly after sunset.
The landscape around Tlemcen adds even more variety. Within just 10 miles, elevation can change by more than 4,000 feet, so valleys and hills nearby might feel much warmer or colder. Winds shift with the terrain too, and breezes from the north and west can bring a real chill in late autumn.
If you’re visiting, you’ll want to pack layers. A light jacket in the morning or evening is pretty much a must, even if the afternoons feel nice and mild.
Tlemcen’s Mediterranean Climate Context
Tlemcen sits in Algeria’s Mediterranean climate zone. Its inland spot and higher elevation actually make it cooler than the coast.
Fall feels like a real shift, as the dry summer gives way to a wetter winter. Rain starts picking up in September and keeps increasing through October and November.
At first, you won’t see much rain, but by late November, it’s possible to get up to 2 inches (50 mm) in a month. Showers don’t last long, but sometimes they pour down pretty hard.
The days get shorter fast. From early September to late November, you lose almost 3 hours of daylight—that change really impacts both the temperature and how people plan their days.
Humidity usually stays moderate. It’s rarely muggy, so the air feels more crisp than sticky.
With mild days, cool nights, and more rain, Tlemcen’s fall climate stands out from the hotter, drier places farther south.
