Fall in Vienna brings a real shift in temperature and mood. You’ll notice cool mornings, mild afternoons in early September, and chilly evenings by late November.
The season moves quickly, swapping comfortable walking weather for brisk days that make you reach for a warm coat.
Rainfall drops off as autumn goes on, but clouds keep rolling in. The sun sets earlier every evening, so you get fewer daylight hours to explore Vienna.
This blend of fading warmth, shorter days, and a higher chance of gray skies really shapes the city’s rhythm in fall.
Winds pick up a bit, adding to that crispness, but humidity stays low enough to keep things comfy.
All these changes come together and give Vienna’s autumn its own vibe. If you’re planning a trip, you’ll want to know what to expect.
Overview of Fall Weather in Vienna
Fall in Vienna means steadily dropping temperatures, shorter days, and more clouds overhead.
You’ll wake up to cooler mornings and feel a gradual change from mild September days to chilly late November weather.
Rain falls less as the season goes on, but you might see the first snowflakes by the end.
Typical Fall Temperature Range
Temperatures in Vienna drop sharply from early September through late November.
In September, you’ll usually get daytime highs in the low 70s °F (about 22°C), with mild nights around 56°F (13°C).
By November, highs sit near 41°F (5°C), and lows hover close to freezing.
So, you start off needing just a light jacket, but by late fall, you’ll want heavier layers.
Nights can feel downright cold in November, especially when frost shows up.
Extreme heat almost never happens after September, though you might catch a warm afternoon or two.
Snow rarely falls in September or October, but it can show up in late November.
On average, Vienna gets about 1.5 inches (4 cm) of snow by the end of November, though some years barely see any.
Seasonal Weather Patterns
Clouds roll in more as fall goes on.
Early September skies can be partly sunny, but by November, overcast days outnumber the bright ones.
This change makes the city feel dimmer as daylight slips away.
Rain happens more in early fall, with a 27% chance of a wet day in early September.
By late November, that chance drops to around 18%, but you can still get showers.
Snow risk ticks up in late fall, but rain stays the main kind of precipitation.
Winds get a little stronger, usually 8–9 mph.
You’ll feel more southerly winds in October and November.
Humidity stays comfortable, and muggy days pretty much don’t happen.
Comparison to Other Seasons
Compared to summer, fall feels cooler, cloudier, and not as humid.
Summer highs can reach the upper 70s °F (25°C), but after mid-September, fall rarely gets that warm.
Rain falls less in fall than in June or July, which are wetter months.
Winter in Vienna is colder and darker, with more snow and highs often below 40°F (4°C).
Spring brings a slow warm-up, longer days, and more sunshine.
Fall sits in between, bridging the gap between summer’s warmth and winter’s chill.
If you like mild weather with fewer crowds, early fall is a great time to visit.
Late fall is colder but quieter, and you’ll see the first hints of winter.
Temperature Trends in Autumn
Fall temperatures in Vienna drop steadily from mild to chilly, and the difference between day and night temps can be pretty striking.
The weather changes month by month, and past years have brought everything from surprise warm spells to early cold snaps.
Average Daytime and Nighttime Temperatures
In early autumn, daytime highs usually hit 22–23°C (72–73°F), especially in September.
Nights cool off to around 12°C (54°F).
By November, highs drop to about 5–7°C (41–45°F), and nights often sit just above freezing.
So, you’ll need light layers in September, but by November, you’ll want a warm coat.
Day and night temps can differ by as much as 10°C (18°F), so it’s smart to pack for both.
Chilly nights creep in earlier than you might expect.
Even in October, after sunset, temps often dip below 10°C (50°F), so evenings can feel crisp even if afternoons are still pleasant.
Monthly Temperature Changes
The shift from September to November happens gradually, but you’ll definitely notice it.
- September: Highs around 21–23°C (70–73°F), lows near 12°C (54°F).
- October: Highs drop to 14–16°C (57–61°F), lows about 7°C (45°F).
- November: Highs average 7–9°C (44–48°F), lows near 2–3°C (36–37°F).
By October, daylight fades faster, and temperatures fall quickly after sunset.
November often feels like winter’s opening act, with morning frost making an appearance.
Mild days above 15°C (59°F) become rare after September.
By late autumn, most days stay under 10°C (50°F).
Record Highs and Lows
Vienna’s climate can throw a few surprises.
Sometimes, September highs have reached 30°C (86°F), giving the city a late taste of summer.
On the flip side, November lows have dropped below -5°C (23°F) in colder years.
These extremes don’t happen often, but they show how much things can change.
You might also get sudden warm or cold spells in October.
Averages are a good guide, but if you pack for a range of temps, you’ll be ready for anything.
Precipitation and Rainy Days in Fall
Vienna’s fall brings cooler air and steady rainfall.
Precipitation shifts month by month, and rainy days get a bit more common as winter nears.
Monthly Precipitation Totals
Rainfall in fall is moderate and pretty consistent.
September usually brings about 50–60 mm of rain, mostly as light or moderate showers.
October follows with 40–50 mm, and November averages 50–55 mm.
These totals are lower than summer’s peak, but rain spreads out enough to make you rethink some outdoor plans.
By late November, you might see a mix of rain and the first snowflakes.
| Month | Average Precipitation (mm) |
|---|---|
| September | ~55 mm |
| October | ~45 mm |
| November | ~50 mm |
No single fall month stands out as especially wet, but the steady rain keeps things damp and cool.
Rainy Days Frequency
Fall usually brings more rainy days than summer.
September has about 11–12 days with measurable rain.
October averages 12–13 days, and November can reach 13–14 days.
Heavy rain is pretty rare.
You’ll mostly get light showers or drizzles that come and go.
A small umbrella or rain jacket comes in handy, since showers can pop up quickly and don’t always last long.
Snow rarely appears before late November, but you’ll notice more cloudy skies and misty mornings.
This dampness makes the city feel colder than the actual temperature.
Transition to Winter Conditions
By late November, rain sometimes mixes with snow.
Daytime highs drop to around 6–8°C, and nights often fall close to freezing.
When that happens, light rain can turn into sleet or wet snow pretty easily.
Cloudy days become more common, and sunshine hours drop off fast compared to September.
With less sun, moisture sticks around on streets and in the air.
If you visit during this time, expect colder, wetter weather.
Waterproof shoes and layered clothes make a big difference as Vienna shifts from mild autumn to the edge of winter.
Humidity and Relative Humidity Levels
Humidity in Vienna rises gradually through fall, moving from late summer’s dry air toward winter’s damp chill.
You’ll feel the difference between September, October, and November, both in the numbers and in how the air feels.
Average Humidity by Month
Relative humidity in Vienna climbs as autumn goes on.
September averages about 65–68%, which feels comfortable most days.
By October, it’s up to 70–74%, and mornings and evenings start to feel a bit damper.
In November, humidity peaks for the season, averaging 78–81%.
That’s one of the highest points of the year, with lots of cloudy days and not much sun.
The air can feel heavier, and cooler temps make it even more noticeable.
Here’s a quick look:
| Month | Average Relative Humidity |
|---|---|
| September | ~65–68% |
| October | ~70–74% |
| November | ~78–81% |
As humidity rises, it can affect how comfortable you feel outside.
Even if it’s not freezing, the dampness in late fall can make the air feel colder than the thermometer says.
Effects on Comfort and Health
September’s moderate humidity feels pretty manageable.
The air isn’t too dry or too damp, so outdoor activities are pleasant.
By October, the extra moisture can make cool days feel chilly, especially if you’re outside for a while.
In November, high humidity and low temps combine for a raw, biting cold.
It’s the kind of dampness that goes right through your jacket.
Wearing layers and water-resistant clothes helps a lot.
For health, rising humidity can affect your breathing.
People with asthma or other respiratory problems might notice more irritation in November’s damp air.
Indoor heating also dries out the air inside, which can lead to dry skin or a scratchy throat.
Using a humidifier indoors and dressing right outside can help you handle Vienna’s fall climate better.
Wind and Wind Speed During Autumn
Vienna’s autumn winds stay steady but don’t get wild.
You’ll feel light to moderate breezes that shift as the season moves along.
Prevailing Wind Directions
Winds in Vienna often blow from the west and northwest, shaped by the Alps and Danube Valley.
These winds bring cooler air as fall goes on and can make evenings feel brisk.
Sometimes you’ll get winds from the northeast, especially in late fall.
That’s when colder continental air rolls in, hinting that winter’s not far off.
The city’s layout matters too—open spaces near the Danube feel windier than sheltered streets in the historic center.
Average Wind Speed
Autumn wind speeds usually sit around 2 to 3 meters per second.
That’s about 7–11 km/h (4–7 mph), which feels like a gentle to moderate breeze.
- August–October: around 2 m/s (gentle air movement).
- November: closer to 3 m/s (breezier, but not extreme).
At these speeds, you’ll see leaves moving and small flags fluttering.
Calm days happen, but gusts can sometimes double the average, especially in open spots.
Impact on Daily Life
Most of the time, Vienna’s autumn wind doesn’t get in the way.
You can walk, bike along the Danube, or sit at an outdoor café without much trouble.
Wind stands out more in open plazas, by the river, or up in the Vienna Woods.
A light jacket or scarf is a good idea for breezy evenings.
Wind can make it feel colder than it really is, especially in November.
That’s when the chill becomes sharper, thanks to the combo of wind and dropping temps.
The steady air movement isn’t strong enough to be a hazard, but it adds to that crisp autumn feeling and keeps the city’s air fresh.
Cloud Cover and Sunshine Hours
During fall in Vienna, skies grow more overcast as the season goes on.
Daylight hours shrink, and sunshine gets harder to come by.
All these changes shape how much light you see each day and how often you run into cloudy skies.
Typical Cloud Cover in Fall
Cloud cover tends to build steadily from early to late fall. In September, you’ll still get plenty of partly cloudy days, but by November, the sky often turns gray and stays overcast.
According to data, mostly cloudy or overcast conditions happen about 41% of the time in September. That number climbs to around 61% in November.
So, by late fall, cloudy skies show up more often than clear ones. The change sneaks up on you, and October brings a real mix—some sunny spells, but the clear days start to fade, especially by the end of the month.
If you’re traveling, you might want to plan for more indoor things to do as the season goes on. Shorter days and heavier cloud cover mean there’s just less outdoor light to work with.
Average Daily Sunshine
Sunshine hours drop off as fall moves along. In September, Vienna gets about 5 to 6 hours of sun per day on average.
By November, you’ll only see about 2 to 3 hours daily. That’s not just the clouds—it’s the days getting shorter, too.
If you’re hoping for time outdoors, you’ll notice the difference between early and late fall. September afternoons can still feel bright, but by November, things get pretty dim and chilly.
Just for context, July’s summer peak brings nearly 9 hours of sunshine each day. Fall really signals the city’s shift toward the darker stretch of winter.
This drop in sunlight definitely affects the mood, especially if you’re out walking or sightseeing late in the day.
Seasonal Changes in Daylight
Daylight hours in Vienna drop off fast once fall hits. Early September feels generous, with the sun popping up before 6:30 a.m. and hanging around past 7:30 p.m. You get about 13 hours of daylight then.
But by late November, things look pretty different. Sunrise doesn’t happen until around 7:30 a.m., and sunset creeps in by about 4:15 p.m., so you’re left with just 9 hours of daylight.
Evenings seem to show up before you’re ready, and mornings just stay kind of dim. Those nearly 4 fewer hours of sunlight really shake up how people plan their days.
If you want to go sightseeing or do anything outside, you’ll probably have to tweak your plans to squeeze the most out of the daylight.
