Fall in Tunis really feels like a breath of fresh air after those relentless summer months. Daily high temperatures start out in the low 30s °C in early September, but by late November, you’ll see them dip to around 19 °C. Evenings get chillier as the weeks go by, which is a welcome change if you ask me.
This shift makes autumn a fantastic time to enjoy the city’s mix of coastal breezes and historic streets. Along with the temperature drop, skies get cloudier, and rain becomes a bit more likely, though you won’t often get heavy storms.
Humidity drops off, too, so the air isn’t nearly as sticky as it is in August. These changes combine to create a really pleasant climate—it’s refreshing and kind of inviting, honestly.
Daylight hours shrink quickly, which changes up the city’s daily rhythm. You’ll catch sunsets earlier and sunrises later, so outdoor plans feel different.
Steady winds and cooler sea temperatures help set a unique mood for exploring both the city and the coast.
Overview of Fall Weather in Tunis
Fall in Tunis means dropping temperatures, shorter days, and more rain. Evenings cool off, hot days fade, and humidity plus wind shift compared to summer.
All of this makes the season a lot more comfortable for getting out and about.
Defining the Fall Season in Tunis
Fall runs from September through November in Tunis. High temperatures fall from about 90°F (32°C) in early September to around 65°F (18°C) by late November.
Nighttime lows also drop, going from about 71°F (22°C) to 51°F (11°C). Day length shrinks fast.
At the start of September, you get almost 13 hours of daylight. By late November, it’s less than 10 hours.
Sunrise comes later, sunset shows up earlier, and that definitely affects how much you can do outside.
Humidity starts off a bit muggy but turns drier by November. This transition gives fall its own vibe, somewhere between the heat of summer and the chill of winter.
General Climate Characteristics
Fall in Tunis brings milder daytime temperatures and cooler nights, plus more clouds as the weeks go by. Clear skies are common in early September, but by late October, you’ll see overcast conditions almost 40% of the time.
Rain picks up as autumn moves along. Monthly rainfall averages about 0.9 inches in September, rising to 1.3 inches in November. October usually gets the most rain.
Heavy storms don’t happen often, but you’ll get light or moderate rain on a few days each month.
Winds get stronger, averaging 9–11 mph. They blow mostly from the north at first, then shift west.
The Mediterranean Sea cools down quickly, dropping from 79°F (26°C) in September to about 66°F (19°C) in November. Swimming gets a lot less tempting.
Comparison to Other Seasons
Compared to summer, fall is just so much more comfortable for being outside. Daytime highs stop hitting the mid-90s°F (35°C), and muggy nights turn into drier, fresher air.
The sun isn’t as harsh, and daylight hours shrink fast.
Winter in Tunis stays milder than you might expect, with highs in the 50s°F (10–15°C), more rain, and stronger winds. Fall lands right in the middle, warm enough for light clothes during the day, but you’ll want a jacket at night.
Spring is a bit like fall, but it warms up faster and has less rain. Fall, by contrast, cools down and gets wetter, setting up for winter.
Average Temperatures in Fall
Temperatures in Tunis during fall slide steadily from summer’s heat toward winter’s chill. Daytime highs drop, evenings mellow out, and the difference between September and November is pretty noticeable.
Monthly Temperature Trends
September still brings the heat, with average highs near 32°C (90°F) and lows around 20°C (68°F). Early in the month, it feels a lot like summer.
October cools things off. Highs hit about 27°C (81°F), and lows dip to 16°C (61°F). It’s a sweet spot for being outside without getting roasted.
November feels like a real shift. Highs come down to about 20°C (68°F), and lows hover near 11°C (52°F). Cooler mornings and evenings become the norm, so you’ll probably want light layers.
| Month | Avg High °C (°F) | Avg Low °C (°F) |
|---|---|---|
| September | 32 (90) | 20 (68) |
| October | 27 (81) | 16 (61) |
| November | 20 (68) | 11 (52) |
Daytime vs Nighttime Temperatures
Early fall days still get hot, especially in September. You’ll want sun protection and light clothes.
Nights start cooling off sooner than you’d expect, which feels great after a warm afternoon.
By mid-October, you’ll notice a bigger gap between day and night. Afternoons feel mild, but after sunset, you might reach for a sweater.
In November, afternoons stay comfortable, but evenings and mornings can feel brisk. If you’re out all day, plan on bringing layers.
Temperature Variations Through the Season
Fall starts off feeling like summer and ends up flirting with winter. September is all about lingering heat, while November feels like a preview of the colder, wetter months ahead.
The change isn’t sudden, but you’ll notice highs and lows dropping a bit each week. Fall is really a season for flexible clothing.
By late November, the weather feels completely different from early September. You go from swimming weather to days better suited for city walks or indoor exploring.
Rainfall and Humidity Patterns
Fall in Tunis brings clear shifts in both rainfall and humidity. Rain becomes more frequent than in summer, and the air holds more moisture as it gets cooler.
This can definitely affect your outdoor plans and what you’ll want to pack.
Monthly Rainfall Amounts
Rainfall climbs steadily through autumn. September averages 35–40 mm, October jumps to 50–60 mm, and November climbs higher, with 55–65 mm.
It marks the change from dry summer to wetter winter. Rain doesn’t fall every day, and when it does, it’s usually moderate.
| Month | Rainfall (mm) |
|---|---|
| September | 35–40 |
| October | 50–60 |
| November | 55–65 |
Year to year, numbers might shift, but the upward trend in autumn is pretty reliable.
Humidity Levels in Autumn
Humidity also rises as fall rolls on. In September, it sits around 60%, so things still feel pretty dry.
By October, it’s usually 65–70%, and in November, it can reach 75%.
Cooler air holds more moisture, and the return of rain makes evenings feel damper.
If you’re visiting, expect more humidity in late fall. Light clothes work for September, but by November, breathable fabrics are a good call.
Typical Rainy Days
Rainy days are rare in early autumn but show up more often by late November. September might only bring 3–4 rainy days, October averages 6–7, and November often gets 8–9.
Most showers don’t last long, clearing up in a few hours. Extended rainy spells are unusual, but gray skies sometimes hang around after the rain stops.
If you’re planning outdoor stuff, October and November need more flexibility. A light rain jacket or umbrella won’t go to waste—surprise showers can pop up even on sunny mornings.
Sunshine and Daylight Hours
Fall in Tunis means shorter days and less sunshine than summer. The daylight hours shrink, and daily sunshine hours drop as clouds become more common.
Average Daily Sunshine
Early fall still brings long, sunny afternoons—8 to 9 hours of sunshine per day isn’t unusual. September skies are often clear, and you can enjoy daylight well into the evening.
By October, you get about 6 to 7 hours of sun each day, as clouds show up more often.
November sees the biggest drop, with only 5 to 6 hours of sunshine. Late fall feels much dimmer, and outdoor plans can get tricky.
Here’s a quick look:
| Month | Avg. Daily Sunshine |
|---|---|
| September | 8–9 hours |
| October | 6–7 hours |
| November | 5–6 hours |
So, early fall is still pretty bright, but by November, you’ll notice the shorter, cloudier days.
Changes in Daylight Duration
Daylight hours shrink quickly. In September, the sun rises before 6:30 a.m. and sets around 7:00 p.m., giving you almost 12.5 hours of daylight.
By October, it drops to about 11 hours, and sunsets happen closer to 6:00 p.m.
November brings the biggest change, with 10 to 10.5 hours of daylight and even earlier evenings.
Losing daylight makes a difference for travel plans and routines. Sightseeing or beach trips are easier in September, but by November, you’ll want to keep an eye on those early sunsets.
From early to late fall, you lose over 2 hours of daylight, so timing matters if you’re counting on natural light.
Wind and Atmospheric Conditions
As fall moves in, Tunis gets cooler air and stronger winds. Wind speed and direction shift, and you’ll feel the difference, especially near the coast.
Prevailing Winds in Fall
Early fall brings winds mainly from the north, which carry cooler air off the Mediterranean. By late September, winds shift more to the west, bringing in drier air from inland.
This transition marks the move from summer’s lighter breezes to autumn’s more unpredictable patterns.
Breezes feel stronger in open areas near the sea. Sheltered neighborhoods don’t notice as much.
Wind direction affects how humid or dry things feel—northern winds add moisture, while western winds dry things out.
That back-and-forth is pretty typical for a city on the Mediterranean coast.
Wind Speed and Direction
Wind speeds rise as fall goes on. In early September, winds average about 14 km/h. By November, they’re often up to 18 km/h.
You’ll definitely notice the difference if you’re outside, especially along the water or in higher parts of the city.
The strongest winds usually show up later in fall, but it’s rare for them to cause any real trouble.
You’ll just get more gusts that make evenings feel colder than the thermometer says.
From September to November, the main wind direction shifts from north to west. By late fall, you’ll get more dry, brisk air, which feels different from the milder, damper breezes earlier in the season.
What to Expect: Seasonal Highlights
In fall, Tunis starts to cool down. Temperatures steadily drop, skies get cloudier, and you’ll probably notice more rain.
Days get shorter, humidity drops, and the wind picks up compared to summer. All these changes affect the weather and what you’ll want to do outdoors.
Common Weather Events
You’ll see daily highs go from about 90°F (32°C) in early September to around 65°F (18°C) by late November. Nights cool off fast too, dropping from the low 70s to the low 50s.
Rain shows up more often, but it’s rarely heavy. In early fall, there’s about a 14% chance of rain on any given day, and that chance climbs a bit as you get closer to November. Most rainy days just bring light showers, not storms.
Clouds start to take over as the season goes on. Early September usually has clear skies, but by late October, you’ll see overcast or mostly cloudy weather almost 40% of the time.
Humidity drops off fast as fall moves along. September can still feel a bit muggy, but by November, the air gets a lot drier. Winds get stronger too, shifting from the north at first, then blowing in from the west later on.
Best Activities for Fall Weather
Cooler air means you can actually enjoy walking through the Medina of Tunis or checking out Carthage’s ruins without sweating through everything. I love wandering markets and museums when the heat isn’t so brutal.
Outdoor dining feels way nicer with milder temperatures. In September and October, evenings are just right for sitting outside at a café—no need to rush inside.
By November, the days get shorter, so it makes sense to mix up your sightseeing with some time indoors, maybe at a gallery or a mosque. If you’re into nature, fall is honestly the best for day trips out to Sidi Bou Said or up in the coastal hills. The breezes are cool, and you won’t have to elbow through crowds.
You can still swim in the Mediterranean in early fall, since the water stays warm around 79°F (26°C). It does cool down to the mid-60s by late November, though, so maybe skip the dip if you’re not a fan of chilly water.
