Fall in Ulan-Ude feels like a dramatic shift. Summer’s warmth disappears fast, and winter starts creeping in before you know it.
You notice the days getting shorter. The air turns crisp, and the landscape changes almost overnight. Average fall weather in Ulan-Ude stays cool, dry, and gets colder each week from September through November.
September still gives you mild daytime temps. By October, the chill settles in, and November often plunges well below freezing. Rain barely shows up, and snow starts taking its place as the season rolls on.
Sunshine hours shrink, so every clear day feels a bit more special against those gray skies.
This season really shows off Siberia’s climate—big temperature swings, not much rain, and steady breezes. If you’re curious about how the city shifts into winter, or you’re planning a trip, you’ll see how the weather shapes daily routines and travel plans.
Overview of Ulan-Ude Fall Climate
Fall in Ulan-Ude brings a sharp drop in temperatures. Days get shorter, and you feel the quick change from mild to harsh.
You can expect cooler days, more clouds, and the growing season wraps up quickly as winter approaches.
Geographic Location and Climate Type
Ulan-Ude sits in southeastern Siberia, pretty close to Lake Baikal, at about 1,732 feet (528 meters) above sea level.
Its spot puts it in a continental climate zone, with those famously long, cold winters and short, warm summers.
The climate falls under the subarctic with dry winters (Dwc) category in the Köppen system. Summers can feel nice, but winters are brutal and stretch on for months.
Because the city sits in a valley surrounded by mountains, you get strong temperature swings between day and night. The terrain also guides the wind, which in fall mostly blows in from the west.
Precipitation stays low compared to a lot of other places. Fall sees rainfall drop quickly, and the air gets drier as the weeks pass.
Typical Fall Weather Characteristics
Temperatures drop fast from September to late November. Highs go from around 67°F (19°C) in early September to about 12°F (-11°C) by late November.
Lows shift from about 46°F (8°C) to -6°F (-21°C). That’s a big swing.
Cloud cover creeps up, and you see overcast or mostly cloudy skies more than half the time. Rainfall drops off hard, starting near 1.5 inches per month in September and getting close to zero by late November.
Snow starts to edge out rain by mid to late fall. Early autumn still brings a bit of both, but by November, most of what falls is snow.
Daylight hours shrink by more than five hours from September to November. Sunrise comes later, and sunset happens earlier. This quick loss of daylight makes late fall feel even colder.
Comparison to Other Seasons
Fall stands out from summer in Ulan-Ude. Summer brings warmer days, usually 20–26°C (68–79°F), longer daylight, and more rain.
In fall, you get freezing temps fast and barely any rain.
Compared to winter, fall feels milder, but it doesn’t last long. Winter lows can hit -21°F (-29°C), much colder than late fall. Snow piles up and doesn’t really melt until spring.
Spring is its own thing. Temperatures climb quickly starting in April, and you get snowmelt with some rain. Fall, though, dries out before the big snows arrive.
So, fall is short but matters a lot—it’s the last breath before Siberia’s long winter.
Average Temperatures in Fall
Temperatures in Ulan-Ude drop fast during fall. Early autumn feels cool, but by late November, it’s basically winter.
You’ll notice big swings between day and night, and both highs and lows slide downward as the weeks go by.
September Temperature Trends
September still hangs onto some summer warmth. Daytime highs start near 67°F (19°C) at the beginning of the month and dip to about 50°F (10°C) by the end.
Nights cool off, dropping from around 46°F (8°C) to about 32°F (0°C).
You get crisp afternoons and chilly evenings, so layering really helps. Early September can still be great for outdoor stuff, but frost starts showing up more often later in the month.
Rain is more likely in September than later on, with a 21% chance of a wet day at first. By month’s end, that chance drops off fast. This is when things shift from a wetter late summer to a much drier autumn.
October Temperature Patterns
October cools down noticeably. Highs average between 37°F (3°C) and 50°F (10°C). Lows often fall below freezing, ranging from 25°F (-4°C) to 32°F (0°C).
By mid-October, frost is the norm, and you might even see the first light snow.
The daily range stays wide, but the chill is real. Cloud cover ramps up, going from about 55% in late September to nearly 65% by the end of October.
Rain chances keep dropping. Rain becomes rare, and snow starts to show up more, even if it’s just a little at first. October is when Ulan-Ude really shifts from autumn into early winter.
November Temperature Changes
November brings in real winter cold. Average highs drop to about 12°F (-11°C) by the end of the month, and lows hit -6°F (-21°C).
You’ll need to prepare for freezing conditions all day. Daytime warmth basically disappears.
Snowfall gets more likely, but total precipitation stays low. Rain almost never happens, replaced by occasional snow showers.
Days are short, with only about 8 hours of daylight by late November. The sun rises much later, making mornings feel extra cold.
November always ranks among the coldest autumn months in Siberia. If you visit now, you’ll get winter conditions, and strong west winds make it feel even colder.
Precipitation and Rainfall Patterns
Fall in Ulan-Ude means less and less rain, fewer wet days, and the first hints of snow. Weather records show a clear move from light autumn showers in September to dry, cold days by November.
Monthly Rainfall Amounts
September usually has the most rainfall of the fall season. You might see around 30–40 mm of precipitation, though some years get a bit more.
That’s a big drop from August, the wettest month, which gets about 73 mm.
October dries out even more, with rainfall down to about 15–20 mm. The air feels cooler and less humid.
November is when winter takes over. Precipitation averages close to 0 mm, and what does fall is usually light snow instead of rain. This sharp drop shows just how dry Ulan-Ude’s climate gets as autumn slips into winter.
| Month | Avg. Precipitation (mm) |
|---|---|
| September | 30–40 |
| October | 15–20 |
| November | ~0 |
Rainy Days Frequency
The number of days with rain drops through fall. In September, you usually get about 7–9 days of rain, and it’s mostly light.
October brings fewer wet days, with 4–6 days of rain or drizzle. The air gets drier, and cooler nights make long rains less likely.
By November, rain pretty much disappears. You might notice occasional snow flurries on about 5–8 days, but there’s not much moisture overall. Fall ends up being one of the driest times of year in Ulan-Ude.
Snowfall Onset in Late Fall
Snow usually starts falling in late October, but it gets more regular in November. The first light snow melts quickly, but by mid-November, it sticks around.
December turns into the snowiest month, but November sets the scene. You can expect about 8–10 snowy days during November, even though there’s not a lot of total precipitation.
This early snow marks the start of Ulan-Ude’s long winter. The city’s subarctic climate means that once snow comes, it’s not going anywhere for months. Travelers should get ready for icy conditions by late fall, since the shift from rain to snow happens pretty reliably before winter really settles in.
Humidity and Atmospheric Conditions
Humidity in Ulan-Ude changes a lot during fall. The air moves from late summer dryness to the moister feel of early winter.
These shifts affect how cool or crisp the air feels, how fast temperatures drop at night, and how comfortable you’ll feel outside.
Average Humidity Levels
In September, you get average humidity around 71%, higher than in summer. October stays about the same, near 70%.
By November, it climbs to about 84%, thanks to the colder, denser air that can’t hold much moisture.
This slow rise means fall starts to feel damper, even if it’s not raining much. Precipitation in September averages about 45 mm, but October drops to 12 mm. November is low too, at about 10 mm, yet humidity keeps going up.
It’s a weird combo—low rainfall but higher humidity. The air feels heavier and chillier in late fall, even when it’s dry. That’s pretty typical for continental climates like Ulan-Ude’s, where cold air masses take over as winter nears.
Daily Variations in Humidity
You’ll notice differences between day and night humidity in fall. In September, daytime air feels mild and not too damp, with humidity dipping into the 60% range.
At night, it rises, often going above 80%, especially as temps drop near freezing.
By October and November, the gap shrinks. Daytime readings stay higher, often 70–80%, and nights push above 85%. Mornings feel especially cold and damp, even if skies look clear.
These swings affect comfort and visibility. Fog pops up more in October and November, with 1–3 fog days per month on average. If you’re out early or planning activities, expect some fog and a chill that feels worse than what the thermometer says.
Sunshine and Daylight Hours
Fall in Ulan-Ude means shorter days and less sunshine as the weeks go by. Both daylight and daily sunshine hours drop, changing how the city feels from September to late November.
Average Daily Sunshine
In September, you usually get 6 to 7 hours of sunshine per day, based on weather records. October brings that down to about 5 hours a day, and by November, you’re looking at only 3–4 hours.
This happens because days get shorter and clouds show up more often.
The sunniest stretch is early September, when skies are clearer. By late November, it’s much cloudier, with overcast skies more than half the time.
This shift changes the city’s mood. Early fall is better for outdoor plans, with more daylight and clearer skies. Late fall feels dimmer, with limited sunshine.
Changes in Daylight Duration
Daylight drops fast during fall in Ulan-Ude. On September 1, you get about 13 hours and 35 minutes of daylight. By November 30, it’s just 8 hours and 11 minutes.
That’s over 5 hours lost in one season.
Sunrise moves from around 6:00 AM in early September to almost 8:30 AM by late November. Sunset jumps earlier too, from 7:30 PM in September to about 4:45 PM at the end of November.
Your daylight for travel, errands, or sightseeing shrinks every week. If you rely on natural light, you’ll really notice it in October and November, when evenings come much sooner.
Wind and Other Weather Factors
When fall rolls into Ulan-Ude, shifts in wind direction, changes in air pressure, and unpredictable cloud cover all shape the daily weather. These things really decide how chilly the season feels and can make a big difference for anyone traveling, spending time outside, or even just trying to see the view.
Typical Wind Speeds in Fall
Winds usually blow in from the west and northwest during fall. Western winds show up most often, making up almost half of what you’ll notice.
Most days, the wind speed stays pretty moderate, usually somewhere between 3–6 meters per second (7–13 mph).
You’ll probably feel stronger gusts in October when cold air sweeps in from Siberia. Those gusts can make it feel way colder than what the thermometer says.
Wind chill really starts to matter in late fall, especially as daytime highs dip closer to freezing.
September usually brings calmer air, so early fall is just nicer for walking around or sightseeing. By November, breezes pick up and sharp gusts pop up more often, which can mess with your outdoor plans, especially if you’re in open spots without much cover.
Air Pressure and Cloud Cover
Air pressure usually stays higher in Ulan-Ude during fall than it does in summer. The area’s continental climate and the approach of winter systems play a role in that.
When pressure stays steady, you’ll often get clear skies, especially in September. You might even catch some long stretches of dry, sunny weather.
Clouds start to roll in more as fall goes on. By October and November, you’ll see overcast skies more often, and low clouds show up a lot in the mornings.
This means less sunshine, so the days feel shorter and definitely cooler.
Precipitation doesn’t amount to much, but you might get a light rain or even an early snow shower in late fall. When pressure drops and weather shifts, it’s a sign that Ulan-Ude’s harsher winter is just around the corner.
Historical Weather Data and Trends
Weather records in Ulan-Ude paint a clear picture of a strong seasonal cycle, shaped by its inland spot and that classic Siberian climate. You’ll spot steady long-term averages, but if you look at recent decades, you’ll notice shifts in temperature and precipitation that really change how fall feels.
Long-Term Climate Records
Historical weather data for Ulan-Ude shows some pretty dramatic temperature swings between seasons. The average annual temperature sits around 0.5 °C (33 °F), and fall brings a quick drop from September’s mild days to November’s freezing nights.
In September, highs usually reach the mid-60s °F (about 18 °C). By November, though, those highs often barely make it above freezing.
Nighttime lows fall even faster, dropping from the mid-40s °F (7 °C) early in the season to below 10 °F (-12 °C) by the end of November.
Precipitation stays modest compared to western Russia. Annual totals average about 347 mm (13.7 in), with most of the rain falling in summer.
Once fall hits, rainfall drops off fast, and snow starts to show up more in November. Snow cover usually starts building in late October, if you check the historical records.
Clouds keep increasing as fall goes on. You’ll get more clear skies in early September, but by late November, overcast days take over.
This steady change, seen again and again in the records, marks the shift from late-summer warmth to the long, cold Siberian winter.
Recent Fall Weather Anomalies
Lately, fall weather in Ulan-Ude has felt a lot more unpredictable than it used to be. Warmer-than-average Septembers now stretch the growing season by a few weeks and push back the first frost.
Farmers have noticed this shift in their records, and honestly, it lines up with the bigger warming trends happening all over Siberia.
Snowfall patterns look different too. November still usually brings reliable snow cover, but sometimes, snow shows up as early as late September.
October doesn’t always bring much rain these days, so the ground can get pretty dry right before winter kicks in.
Winds have picked up a bit in late fall compared to what people remember from the past. Westerly winds take over, and those strong November gusts seem to show up more often now.
These wind changes can make travel trickier and shake up daily routines, especially with daylight fading so quickly by late fall.
Temperature swings still stand out. Even though the average temps are creeping up, sudden cold snaps sometimes drop the lows below -15 °F (-26 °C) in November.
So, despite the gradual warming, Ulan-Ude’s continental climate still packs a punch when it wants to.
