If you’re planning a trip to Annaba in the fall, you’ll notice the weather shifting from warm summer days to cooler, breezier conditions. Average daytime highs start around 29°C (84°F) in early September and drop to about 19°C (65°F) by late November. Nights cool off too, from 20°C (68°F) down to nearly 10°C (50°F). This steady change makes fall one of the best times to experience the city.
As the season moves along, the skies get cloudier. Early September usually brings bright, clear days, but by late November, overcast skies show up more often.
Rainfall follows a similar pattern. It starts out light but increases steadily, making the coastal air feel fresher and the landscape greener.
The Mediterranean Sea shapes the season quite a bit. Water temperatures fall quickly from the mid-20s °C to the upper teens. Winds pick up too, shifting from north to west, which adds a brisk edge to evenings along the coast.
This mix of cooling temperatures, more rain, and changing sea conditions really defines what fall in Annaba feels like.
Overview of Annaba’s Fall Climate
In fall, Annaba moves away from summer heat toward cooler, wetter weather. Days get shorter, rain falls more often, and temperatures drop, all of which shape outdoor activities and the city’s overall feel.
Geographical Location and Climate Classification
Annaba sits in northeastern Algeria along the Mediterranean coast, close to Tunisia. Its coastal setting has a huge impact on the weather you’ll get in fall.
The city stands at about 120 meters (400 feet) above sea level. Thanks to this modest elevation and its spot near the sea, you get milder seasonal swings than you’d find inland.
According to the Köppen-Geiger climate classification, Annaba falls under a Mediterranean climate with hot summers (Csa). In fall, this means moderate temperatures and more rain.
Average high temperatures in September sit around 28°C (82°F), dropping to about 21°C (70°F) by November. Nighttime lows go from 19°C (66°F) in September down to 12°C (54°F) in November.
These steady changes mark the move into the cooler season.
Mediterranean Influences on Weather Patterns
The Mediterranean Sea plays a big part in Annaba’s fall weather. Warm sea surface temps in early fall keep things mild, but cooler air masses later on bring more clouds and rain.
Rainfall rises sharply after the dry summer. September averages about 25 mm, but by November, totals often reach 60 mm or more.
You’ll notice more wet days as fall goes on, with November ranking among the wettest months.
Humidity rises too. While summer can get muggy, fall air feels more comfortable, even though dampness becomes common.
Winds from the north and northwest grow stronger, especially late in the season, and they add a chill to evenings.
All these factors combine to make the season both refreshing and unpredictable. You might get sunny stretches, then sudden showers—pretty typical for Mediterranean coastal cities.
Comparison With Other Algerian Cities
Annaba’s fall climate is different from other Algerian cities. In Algiers, farther west on the coast, temperatures run similar but rainfall isn’t quite as heavy. Algiers averages about 50 mm in November, compared to Annaba’s 60+ mm.
Head inland and the contrast gets sharper. In Constantine, about 150 km southwest, fall temperatures are cooler because of the higher elevation. Highs in November average 17°C (63°F), several degrees below Annaba. Nights drop close to 7°C (45°F), so it feels much colder.
Down south, Tamanrasset in the Sahara has a totally different pattern. Fall there stays dry and warm, with almost no rain and daytime highs near 26°C (79°F) in November.
So, Annaba’s mix of mild coastal temps and higher rainfall really sets its fall weather apart in Algeria.
Typical Fall Temperatures in Annaba
In Annaba, fall brings a move from warm late-summer days to cooler, early-winter weather. Both daytime highs and nighttime lows drop steadily, and the difference between day and night temps gets more noticeable.
Average High and Low Temperatures by Month
September usually brings average highs near 29°C (84°F) and lows around 20°C (69°F). By October, highs fall closer to 25°C (77°F), with lows near 16°C (61°F).
November cools down more, with highs averaging 18°C (65°F) and lows near 11°C (51°F).
These numbers show the steady cooling that defines Annaba’s fall season. Early September rarely goes above 33°C (91°F), and late November seldom drops below 7°C (45°F).
| Month | Avg High °C (°F) | Avg Low °C (°F) |
|---|---|---|
| September | 29 (84) | 20 (69) |
| October | 25 (77) | 16 (61) |
| November | 18 (65) | 11 (51) |
Day-Night Temperature Variations
As fall goes on, you’ll notice bigger gaps between daytime and nighttime temperatures. In September, the difference is about 9°C (16°F). By November, it widens to nearly 14°C (25°F).
Days often feel mild or warm, but evenings cool down quickly. You might wear light clothes during the day, then need warmer layers at night.
The nearby Mediterranean helps keep things from getting too extreme, but inland breezes can still bring sharp drops after sunset.
Clear nights make these swings even bigger, as heat escapes fast. Cloudier days smooth things out a bit, keeping nights slightly warmer.
Historical Temperature Trends
Annaba’s fall weather follows a pretty reliable cooling trend. Average highs drop by almost 11°C (19°F) from early September to late November. Average lows fall by about 10°C (18°F).
Historical records show that record lows in November can get close to 5°C (41°F), though freezing is rare. On the flip side, some hot September days can climb above 32°C (90°F).
This pattern fits the city’s Mediterranean climate, where summers get hot and dry but fall cools down quickly and rain picks up. You can usually count on a steady cool-down, not sudden extremes.
Rainfall and Humidity During Fall
Fall in Annaba brings a steady change from dry late-summer days to wetter, more humid weather. Rain increases each month, and humidity rises as cooler air holds more moisture.
Monthly Precipitation Levels
Rainfall in Annaba jumps as fall goes on. In September, you’ll usually get less than 1 inch (about 20 mm). By November, totals rise to around 2.5 inches (about 65 mm) in a typical month.
This fits the broader Mediterranean climate of northern Algeria. Early fall feels pretty dry, but by late fall, rain gets heavier and more frequent.
October acts as a transition, with totals between 1.5 and 2 inches (40–50 mm).
If you’re planning outdoor activities, keep this in mind. September offers more dry days, while November brings wetter conditions that could affect travel or sightseeing.
| Month | Average Rainfall |
|---|---|
| September | ~0.7 in (20 mm) |
| October | ~1.5 in (40 mm) |
| November | ~2.5 in (65 mm) |
Humidity Patterns
Humidity rises along with the rain. In September, relative humidity often stays moderate, so the air feels comfortable even with leftover summer warmth.
By October, you’ll notice more moisture in the air. Mornings and evenings start to feel damper, and by November, humidity hits its highest fall levels, making for cooler, damp days.
This added humidity affects comfort both inside and outside. Clothes take longer to dry, and the air feels heavier, especially near the coast.
If you’re traveling, pack light layers that can handle both mild warmth and damp conditions.
Rainy Days and Seasonal Variability
Rainy days become more common as fall goes on. September usually brings only a few wet days, often less than 4 or 5 for the whole month. By November, you can expect around 8 to 10 days with measurable rain.
Rain varies from light showers to heavier downpours. Most of it falls during short, passing storms, not all-day events.
You might wake up to sunshine and get rain by afternoon.
Seasonal shifts bring some unpredictability. Some years, October gets unusually wet or November stays drier than usual.
If you visit in fall, it’s smart to pack a compact umbrella or light rain jacket. That way, Annaba’s weather won’t catch you off guard.
Wind, Sunshine, and Sea Conditions
During fall in Annaba, you’ll get steady breezes, moderate sunshine, and sea temperatures that stay comfortable into late October.
Prevailing Winds and Speeds
In fall, winds along Annaba’s coast mainly blow from the north and northwest. These breezes bring in cooler air from the Mediterranean, balancing out the mild daytime warmth.
Average wind speeds run between 10–15 km/h (6–9 mph), but gusts can get stronger on unsettled days.
You’ll notice the wind more in open coastal spots than in sheltered inland neighborhoods.
September usually feels calmer, while October and November bring a bit more wind as the weather patterns shift.
These winds don’t usually disrupt travel, but they can make the sea choppier now and then.
If you’re sailing, fishing, or just hanging out on the beach, keep in mind that wind direction affects wave height and local conditions.
Even a light breeze can make the shoreline feel cooler, especially at night.
Average Sunshine Hours
Annaba gets a good amount of sunshine in fall, though the days get shorter as the season goes on.
- September: about 8–9 hours per day
- October: about 7 hours per day
- November: about 5–6 hours per day
Clear skies are common in September, while October brings a mix of sunny and partly cloudy days.
By November, cloud cover increases along with the rain.
You’ll have enough daylight for sightseeing, but early sunsets make evenings feel longer.
The sun is strong enough in September to need protection, but by late fall, the intensity drops.
Outdoor activities like hiking or walking by the coast stay pleasant, as the balance of sun and cool air makes things less tiring than in summer.
Sea Temperature and Coastal Weather
Mediterranean waters around Annaba stay warm well into fall. In September, the sea averages 24–25°C (75–77°F), perfect for swimming.
By October, it cools to around 22°C (72°F). In November, it drops further to 19–20°C (66–68°F).
This slow cooling means you can enjoy water activities through October, though November feels brisk for most swimmers.
The coast often gets a light morning haze that clears by midday. On windy days, waves might get rougher, but calm spells are still common.
Humidity drops compared to summer, so the air feels fresher by the sea.
If you like quieter beaches, fall is a great time—fewer crowds, but still nice for walking, fishing, or short swims.
Notable Weather Extremes in Annaba’s Fall
During fall, Annaba moves from warm late-summer highs to cooler early-winter conditions, and sometimes the weather goes outside the usual averages. These extremes can shape your plans for outdoor activities, travel, and even what you pack for your visit.
Record Low and High Temperatures
Fall in Annaba usually brings temperatures between the mid-60s °F and mid-80s °F. Still, some years break the pattern.
Highs sometimes push above 90°F (32°C) in early September. That can feel more like summer than fall, honestly.
On the flip side, lows can slip into the mid-40s °F (7–8°C) by late November. Freezing nights rarely happen, but cooler evenings might catch you off guard if you’re expecting only mild Mediterranean weather.
Just to give you an idea:
- Typical September high: ~84°F (29°C)
- Typical November low: ~51°F (11°C)
- Rare extremes: below 45°F (7°C) or above 91°F (33°C)
You’ll want to pack for both warm afternoons and chilly nights, especially if you’re heading to the coast or hills outside the city.
Unusual Weather Events
Annaba’s fall weather doesn’t always match the sunny Mediterranean stereotype. Cloud cover builds fast as the season goes on. By November, you’ll see overcast or mostly cloudy skies almost half the time.
Rain picks up, too. Early fall brings light showers, but late November can dump over 2.5 inches of rain in a month. While that’s not much compared to northern Europe, it’s enough to mess with outdoor plans.
Every so often, strong winds sweep through. Wind speeds jump from about 7 mph in September to more than 10 mph by late fall. The direction shifts from north to west, and those breezes can make the coast feel chillier than you’d expect.
Heavy downpours and even localized flooding have happened before, though it’s not common. If you visit in late fall, keep an eye on local forecasts, especially if you’re driving or heading near rivers and low-lying roads.
How Fall Weather Impacts Daily Life in Annaba
Cooler air, shorter days, and more rain all change how people spend time outside and how they take care of their homes in Annaba during fall. These shifts affect everything from fun outings to daily routines.
Outdoor Activities and Tourism
Early fall still feels beachy. You can swim or walk by the sea, since the water stays warm around 78°F. Later in the season, the Mediterranean cools down to about 65°F. Swimming loses its appeal, but coastal walks remain pleasant.
Rainfall climbs from about 0.7 inches to 2.5 inches each month. Outdoor plans need some flexibility. Carrying a light rain jacket isn’t a bad idea if you’re exploring historic sites or hiking the hills.
Tourists keep coming through fall, but the crowds thin out after summer. Daytime highs between 65°F and 84°F make sightseeing at places like the Basilica of St. Augustine or Annaba’s lively markets much more comfortable.
If you like festivals or cultural events, fall still offers plenty. Cooler air and a drop in muggy days—from 72% down to almost none—make walking tours and outdoor gatherings way more enjoyable.
Home and Lifestyle Adjustments
At home, you start to notice the need for small seasonal changes. Nights dip into the low 50s°F, so you’ll probably reach for light blankets or swap in warmer bedding.
You might not crank up the heat just yet, but getting ready for those cooler evenings keeps your place cozy. It’s honestly kind of nice when the air isn’t sticky anymore.
Humidity drops off fast, which takes away that muggy summer feeling. Indoor spaces feel a lot more comfortable, and you don’t have to run fans or open windows all the time.
But with more rain, you should check windows and roofs for leaks. It’s not fun to discover a drip in the middle of the night.
Daylight hours shrink—by more than three hours, actually—which can throw off your routine. You might find yourself running errands or tackling yard work earlier just to catch the sun.
Winds pick up, shifting from the north to the west. As gusts climb from 7 to 11 mph, it makes sense to secure patio furniture or even dry clothes inside.
Honestly, these little adjustments make the season a lot smoother.
