Fall in Andorra la Vella feels like a real shift from the warm buzz of summer into something cooler and crisper. Average daytime highs drop from the low 60s °F (around 16°C) in September to the low 40s °F (about 6°C) by November. Nights get much colder, especially as winter creeps closer, so you’ll want to bring layers.
Rainfall shapes autumn here, too. September usually stays pretty mild with lighter showers, but October often gets the wettest conditions of the season. By November, rain mixes with early snow, hinting that winter’s just around the corner.
Daylight hours slip away quickly, going from over 12 hours in September to less than 10 by late November. That, plus the chillier air, gives fall a totally different vibe than the endless summer days. If you’re planning to explore the city or hit the mountains, fall offers a quieter, more relaxed pace.
Overview of Fall Weather in Andorra la Vella
Fall in Andorra la Vella means cooler temps, shorter days, and more rain than summer. The season moves from those mild September days to chilly November nights, and the weather can change fast because of the city’s mountain location.
Typical Fall Climate Characteristics
In September, you’ll get average highs near 16°C (61°F), and nights cool off to about 7°C (45°F). By November, daytime highs drop to around 6°C (43°F), and lows often dip below freezing.
Rain sticks around in autumn, with October being the wettest at about 86 mm (3.4 in). Showers are usually light, but higher elevations might see snow by late October.
Daylight drops from about 12.5 hours in September to under 10 hours in November, which can limit outdoor plans. Humidity stays pretty moderate, but the cool air makes evenings feel damp. There’s a clear shift from crisp early fall to wintry conditions by the end of the season.
Comparison With Other Seasons
Compared to summer, fall is cooler and wetter. Summer highs hover around 20°C (68°F) with long, bright days over 14 hours. Fall quickly shortens both the warmth and the daylight.
Winter is a whole different story. January highs only reach 1–2°C (34–36°F), with heavy snow and not much sun. Fall acts as a bridge, giving you milder days before deep winter sets in.
Spring has its own thing going on. Both spring and fall bring variable weather, but spring slowly warms from 5°C (41°F) in March to 13°C (55°F) in May. Fall, on the other hand, cools down. April actually gets more rain than early fall, but snow isn’t as common in spring.
So, autumn stands out for its balance of cool air, colorful scenery, and those first hints of winter.
Geographical Influences on Weather
Andorra la Vella sits at about 1,000 meters (3,280 feet) in the Pyrenees Mountains. This elevation keeps things cooler than in the lowlands nearby.
Surrounding peaks, many over 2,500 meters (8,200 feet), make weather change quickly. Cold air often funnels into the valley, causing sudden temperature drops. The mountain slopes get more precipitation, which explains the wetter weather in October and November.
Since the city is landlocked between Spain and France, it doesn’t get any sea breezes to moderate the climate. Mountain air masses rule here, creating sharp seasonal shifts. You’ll probably notice how fast things can change in just a day, especially in late fall when snow hits the higher peaks while rain falls in the city.
Temperature Patterns During Fall
Temperatures in Andorra la Vella drop steadily from late summer into early winter. You’ll notice shorter days, cooler nights, and more swings between mild afternoons and chilly evenings. These changes really shape how you plan your days and what you wear.
Average Daytime and Nighttime Temperatures
In September, daytime highs sit around 16°C (61°F), and nights drop to about 7°C (45°F). By October, afternoons reach closer to 13°C (55°F), and nights often fall to 4°C (39°F).
November brings a sharper chill. Daytime highs only average 6°C (43°F), and lows hover near -2°C (28°F). Early fall afternoons feel comfortable, but by late fall, you’ll need to be ready for near-freezing nights.
The gap between daytime and nighttime temps gets even wider as fall goes on. You might wear lighter clothes during the day in September, but by October and November, you’ll want much warmer layers at night.
Temperature Fluctuations by Month
September still feels mild, with highs in the lower 60s °F and cool evenings. It’s honestly one of the best months for sightseeing.
By October, temps drop steadily. Highs hang out in the mid-50s °F, and nights can dip into the upper 30s °F. There’s more variety—some days stay mild, others feel pretty chilly.
November turns wintry. Highs barely get above the low 40s °F, and frost shows up at night. You’ll see fewer mild days and more cold spells as winter approaches.
Notable Temperature Extremes
Averages tell part of the story, but extremes pop up too. In September, warm spells sometimes push highs toward 20°C (68°F), but they don’t last long.
By October, sudden cold fronts can bring early frosts, with nighttime lows slipping below freezing. These usually happen after clear evenings when heat escapes fast.
In November, cold snaps sometimes push temps well below -5°C (23°F) at night, especially in higher parts of the valley. You really need to be ready for a mix of conditions, even in the same week.
Rainfall and Precipitation Trends in Autumn
Autumn in Andorra la Vella gradually shifts toward wetter conditions. Rainfall increases compared to summer, and rainy days become more common as the season goes on, which definitely affects outdoor plans.
Monthly Average Rainfall
Rainfall in autumn isn’t extreme, but you’ll notice it. September usually gets around 80–90 mm, October goes up to about 95–105 mm, and November often reaches 100–110 mm. Autumn is one of the wetter times of the year, though not quite as rainy as spring.
Here’s a quick look at average rainfall:
| Month | Average Rainfall (mm) |
|---|---|
| September | ~85 mm |
| October | ~100 mm |
| November | ~105 mm |
Precipitation can fall as rain or, by late November, as early snow at higher elevations. This uptick in moisture signals the shift from mild autumn to the edge of winter.
Frequency of Rainy Days
Rainy days increase as fall moves along. September usually brings about 11–12 wet days, October averages 12–14 days, and November climbs to 14–15 days.
You might see rain on nearly half the days in late autumn. The rain usually comes in short, frequent bursts instead of long storms.
While totals aren’t huge compared to some places in Europe, the steady rainfall means you’ll want to keep waterproof gear handy and check the forecast more often as fall goes on.
Impact on Local Activities
Rain patterns affect how you enjoy the city and mountains. In September, mild showers rarely mess up hiking or sightseeing, and trails stay pretty accessible. By October, wetter weather can make paths muddy and tricky, so sturdier shoes help.
In November, rain and cooler air sometimes bring the season’s first snow to nearby ski areas. That’s when winter sports prep begins.
Around town, rain usually stays light enough that you can still walk around with just an umbrella. Cafés and indoor spots get more appealing when showers pick up.
Sunshine, Daylight, and Humidity in Fall
During fall in Andorra la Vella, days get shorter, sunshine hours drop, and the air turns cooler and clearer. Rain stays steady, but humidity doesn’t get too high, especially compared to summer. These shifts make fall feel pretty comfortable outdoors.
Average Daily Sunshine Hours
Sunshine hours tick down as fall goes on. In September, you’ll get about 6 hours of sun each day. By October, it’s around 5 hours, and in November, it hovers near 5 hours.
The change is gradual, but you still get enough bright spells for outdoor plans. Summer can bring 8–9 hours of sun, so fall feels more balanced between sun and clouds.
Cooler afternoons are more common, especially in the shade. If you’re planning to be outside, expect shorter stretches of direct sunlight than earlier in the year.
Daylight Duration Changes
Daylight hours shrink quickly in fall. In September, you get about 12 hours of daylight. By October, it’s down to 11 hours, and in November, just 10 hours.
| Month | Average Daylight Hours |
|---|---|
| September | 12 |
| October | 11 |
| November | 10 |
This steady drop means evenings get dark earlier, so you’ll want to plan hikes and sightseeing earlier in the afternoon.
Shorter days really underline the shift from the bright, easygoing vibe of late summer to the longer nights of early winter.
Humidity Levels Throughout Fall
Humidity in Andorra la Vella stays pretty low during fall. Unlike summer, when the warm air can feel heavy, autumn is cooler and drier.
You’ll usually get comfortable humidity levels without big spikes. The cool temps help balance out the moisture, so you rarely feel sticky or weighed down.
That makes fall one of the nicer times for walking around town or exploring the mountains. The crisp air and moderate rain create a fresh atmosphere that’s perfect for outdoor adventures.
Travel Considerations for Visiting Andorra la Vella in Fall
Fall in Andorra la Vella brings cooler temps, shorter days, and more frequent rain compared to summer. These changes affect when you should visit, what you can do outside, and how you’ll want to pack.
Best Times to Visit for Pleasant Weather
September gives you the mildest autumn weather, with highs around 16°C (61°F) and comfortable evenings. Rain is more frequent than in summer but usually doesn’t ruin plans. Daylight lasts over 12 hours, so you have plenty of time to explore.
In October, temps drop to about 12°C (54°F) during the day, and nights get chilly. Rain ramps up, making it the wettest month of fall. November brings cold weather, with highs near 6°C (43°F) and frost showing up often.
If you want crisp but manageable weather, early to mid-September is your best bet. October works for folks who like cooler air and smaller crowds. November is for those who don’t mind the cold and want to catch the city as it heads into winter.
Outdoor Activities and Events
Autumn is a great time for hiking in the Pyrenees around Andorra la Vella. Trails are less crowded than in summer, and the changing leaves make the scenery pop. September and early October are safest for longer hikes, since snow is rare at lower elevations.
As rain becomes more common, plan on shorter walks or stick to city sightseeing in October and November. Museums, thermal spas, and shopping in the city center are solid alternatives when the weather turns wet.
Fall also brings cultural events. Local festivals celebrate food, music, and traditions, giving you a chance to experience Andorran culture beyond the outdoors. Timing your visit with these events can really add something extra to your trip.
Packing Tips for Autumn Visits
Get ready for a pretty wide range of temperatures. Pack layered clothing like long-sleeve shirts, sweaters, and a medium-weight jacket.
You’ll want a waterproof outer layer, especially in October, since that’s when rain really picks up.
Grab comfortable walking shoes with good grip, since city streets and mountain paths can both be slippery.
If hiking is on your list, don’t forget lightweight gloves and a hat for those chilly mornings.
Daylight fades fast in fall. If you plan to be out late, toss a small flashlight in your bag.
Packing smart makes it way easier to stay comfortable, whether you’re wandering the city or heading into the valleys.

You’ll notice the shift—not just in the weather, but in how people spend time outside.
Key Differences in Temperature and Rainfall
During summer, daytime highs usually land between 17°C and 21°C (63°F to 69°F). There’s a ton of daylight, about 15 hours in June.

Once fall rolls around, temperatures start dropping. In September, highs average 16°C (61°F). By November, you’re looking at about 6°C (43°F) during the day.
Nights can get close to freezing, so it might feel colder than you expect.
Daylight shrinks fast, from 12.5 hours in September down to under 10 hours in November.
Rain picks up in autumn. October tends to be the wettest, with about 86 mm on average.
Compared to summer, fall definitely feels damper and cooler, especially with all that mountain air holding onto moisture.

|---|---|---|---|
| Summer (Jun–Aug) | 17–21°C | 63–72 | 14–15 |
| Fall (Sep–Nov) | 6–16°C | 54–86 | 10–12.5 |
Seasonal Shifts in Local Life
When summer rolls into Andorra la Vella, you’ll find yourself swept up in open-air festivals, hiking, and plenty of sightseeing. Warm days stretch on and practically invite you to get outside, whether you’re wandering the mountains or just strolling city streets.
Restaurants and terraces buzz with people, and it’s not unusual to see them packed well into the night. There’s just something about those long evenings that keeps everyone out a little later.
Then fall sneaks in and changes the pace. Days get shorter, and the air cools, so outdoor events start to fade away. Locals turn their attention to winter, getting ready for what’s coming next.
Tourists shift gears too, choosing quieter museum visits or cozy cafés instead of full-day hikes. Shops roll out seasonal goods, and those mountain trails? They empty out as the weather gets chillier and a bit damp.
By November, you’ll spot more people heading indoors for dinner, and everyone seems to be gearing up for ski season, which is about to take over the town.
