Fall in Petropavlovsk-Kamchatsky brings a real mix of cooling temperatures, shifting daylight, and the first signs of winter. Daily highs slide from mild in early September to freezing by late November, and lows drop well below zero as the weeks tick by.
You really feel this steady change, and it shapes how you experience the city and the wild landscapes around it. Rain and snow trade places as autumn rolls forward.
September still gets plenty of rain showers, but by late fall, snow takes over and gets much heavier. Cloud cover builds through the season, and the days shrink fast—you lose nearly six hours of daylight from start to finish.
Wind and the coastal vibe also shape the season’s feel. Stronger gusts sweep in as autumn deepens, and the nearby Pacific chills sharply, adding a bite to the air.
These shifts make fall feel transitional but also pretty distinct, setting up the long winter ahead.
Overview of Fall Weather in Petropavlovsk-Kamchatsky
Fall here means a steady drop in temperatures, shorter days, and a shift from rain to snow. Early in the season, you get cool, wet weather, but as winter gets closer, it turns colder and windier.
General Climate Characteristics
During fall, daily high temperatures drop from about 61°F (16°C) in early September to near 30°F (-1°C) by late November. Nighttime lows fall from around 47°F (8°C) to 18°F (-8°C).
Rain rules September, but by November, snow is the main event. Rainfall drops from about 3.1 inches per month in early fall to under 2 inches by late fall.
Snow piles up quickly, often hitting 16 inches in November. Skies stay cloudy or overcast more than half the time.
Wind speeds pick up as the season goes, rising from 5–6 mph in September to over 10 mph by November. Winds usually come from the west, which makes things feel even chillier.
Daylight disappears fast. In September, you get more than 13 hours of light, but by late November, only about 8 hours are left. This sharp drop really changes how you plan outdoor stuff and travel.
Comparison to Other Seasons
Compared to summer, fall feels colder and darker, no doubt about it. Summer highs often stick in the 50s and low 60s°F (10–17°C) with long days, but fall loses warmth and sunlight in a hurry.
Winds get stronger, and the skies are more unsettled. Winter is way harsher.
Fall still gives you some above-freezing days, but winter brings long stretches of subfreezing temps, heavy snow, and relentless winds. Fall acts as a bridge, with rain giving way to snow and conditions getting rougher.
Spring warms up more slowly, with snow melting through April and May. Fall cools off much faster, and the growing season ends by early October.
It’s honestly one of the shortest and most unpredictable seasons in Petropavlovsk-Kamchatsky.
Average Fall Temperatures
Fall in Petropavlovsk-Kamchatsky brings a sharp drop in temperatures from early September to late November. The cooling feels steady and obvious, with things shifting from cool and damp to cold and snowy by the end.
Daily Highs and Lows
Daily highs fall from about 61°F (16°C) in early September to around 30°F (-1°C) by late November. Lows do the same, dropping from roughly 47°F (8°C) to 18°F (-8°C).
You’ll often start fall with mild afternoons, but by the end, it’s freezing day and night. Early September still feels a bit like late summer, but late November is definitely winter’s doorstep.
Sometimes, you get surprises. Highs can reach the upper 60s°F (20°C) in September, and late fall lows might dip into the single digits.
Packing layers is a must if you’re heading outdoors.
Temperature Trends by Month
September is the mildest month of fall. Highs stay in the 50s°F to low 60s°F (10–16°C), and nights usually stay above freezing.
It’s probably the best time for outdoor plans. By October, things cool off quickly.
Highs drop into the 40s°F (4–9°C), and lows often hit the 30s°F (0–4°C). Frost shows up, and you might see the first snow mixed with rain.
November is a clear jump to winter. Daytime highs average near 32°F (0°C), and nights go well below freezing.
Snowfall ramps up, and much of the month is just cold.
| Month | Avg High | Avg Low | Conditions |
|---|---|---|---|
| September | 61°F / 16°C | 47°F / 8°C | Mild, cool nights |
| October | 46°F / 8°C | 34°F / 1°C | Chilly, frost likely |
| November | 30°F / -1°C | 18°F / -8°C | Cold, frequent snow |
Notable Temperature Extremes
Averages tell part of the story, but the extremes really show how much things swing. In early fall, highs can still climb near 70°F (21°C), especially on clear September days.
These warm spells don’t last long, but they’re nice when they happen. On the flip side, late November can bring lows near 7°F (-14°C).
Add wind, and it feels even colder. You might start September with a comfortable hike and end November dodging icy streets and heavy snow.
That rapid change is just classic fall in Petropavlovsk-Kamchatsky.
Precipitation and Rainfall Patterns
Fall brings a steady drop in rainfall as the weeks go by. Early autumn feels wetter, then things shift toward drier, colder weather by late fall.
Monthly Rainfall Totals
September usually measures close to 80–90 mm of rain, so it starts out pretty damp. October actually peaks at about 130–140 mm, making it the wettest month of the year.
Heavy rain events are most common then. By November, totals drop sharply to around 60–70 mm.
Colder air cuts down on liquid precipitation, and snowfall starts to mix in. So, even though rainfall totals drop, overall precipitation doesn’t really go down.
| Month | Average Rainfall (mm) | Notes |
|---|---|---|
| September | ~85 mm | Mild, frequent showers |
| October | ~135 mm | Peak rainfall of the year |
| November | ~65 mm | Rain mixed with snow |
That’s the shift—from a wet early fall to a drier, colder late autumn.
Frequency of Rainy Days
Rain spreads out over a lot of days, not just a few big storms. September usually brings 13–14 rainy days, and October averages 14–15 days with measurable precipitation.
By November, the number drops to about 10–11. But that’s because more days bring snow instead of rain.
So, you still get plenty of wet weather, just colder and in different forms. Waterproof clothing and layers are a must for anyone spending time outside.
Transition to Snowfall
As November rolls in, rainfall slowly gives way to snow. You might still see rain early in the month, but by the second half, snow showers are more common.
This change isn’t sudden. Some days bring sleet or freezing rain.
By late November, snow is a sure thing, and winter really starts to settle in. Travelers need to prep for slippery roads and possible delays.
For locals, it’s the signal that autumn’s rain is over and winter’s snow is here.
Humidity and Cloud Cover
Humidity in Petropavlovsk-Kamchatsky stays pretty steady through the fall, while cloud cover creeps up as the season goes. The air feels drier than in many coastal cities, but the skies tend to turn gray and overcast.
Typical Humidity Levels
Humidity rarely gets uncomfortable here in fall. Dew points stay low, so the air feels cool and crisp instead of muggy.
Humidity levels don’t swing much, even when temperatures do. The chance of a muggy day is basically 0% all season.
Even early autumn, when the ocean’s still a bit warm, the air just doesn’t hold enough moisture to get sticky. Outdoor activities are more comfortable, even as the temperatures drop.
You’ll need to dress for the cold, but you won’t have to deal with heavy, damp air. Honestly, it’s a relief if you’re used to humid falls elsewhere.
The climate here gives you a dry, cool feel that’s different from wetter, muggier coastal areas.
Prevalence of Cloudy Conditions
Cloud cover builds gradually from early to late fall. In early September, skies are clear or partly cloudy about half the time.
By November, overcast days are common, with the sky covered 56% of the time. The clearest day usually comes in early September, with about a 51% chance of clear or mostly clear skies.
After that, clouds keep piling on as colder air moves in. Expect a shift from brighter days to more frequent gray skies by late autumn.
It doesn’t always mean rain or snow, but it does affect visibility and the overall mood. For planning, bring layers and get ready for limited sunshine most of the season.
Even when it’s not raining, the clouds tend to dominate.
Wind Conditions in Autumn
Autumn winds in Petropavlovsk-Kamchatsky shape how the season feels. Cooler air from the Pacific Ocean mixes with the rugged terrain, creating steady breezes and frequent gusts.
These winds really affect comfort, outdoor plans, and even the sea along the coast.
Average Wind Speed
You’ll notice moderate to strong winds across the city and coastline. Average wind speeds range between 15–25 km/h (9–15 mph), but gusts can go higher, especially near open water or up in the hills.
The coast keeps winds steady, and calm days are pretty rare. On exposed headlands, speeds usually stay at the higher end.
Inland areas, with some shelter from hills, get slightly weaker winds. To keep it simple:
- Typical daily range: 15–25 km/h
- Occasional gusts: 30–40 km/h
- Stronger bursts: over 45 km/h during storms
These conditions make it feel colder than the thermometer says. If you’re outside, wear layers and something wind-resistant.
Seasonal Wind Trends
Winds in September are usually milder, still shaped by leftover summer patterns. By October, stronger northwest and northeast flows show up as colder air arrives.
That brings more gusts and a sharper chill. November is the windiest part of fall.
Storms from the North Pacific can push speeds well above average, especially along the shore. Inland valleys still get breezy, but they’re less exposed than the coast.
Expect more variability in wind direction late in the season. While westerly winds usually lead, easterly or southerly flows can pop up during passing systems.
These shifts can change sea conditions fast, so if you’re relying on ferries or fishing trips, keep your plans flexible.
Daylight Hours and Seasonal Changes
During fall in Petropavlovsk-Kamchatsky, daylight drops off quickly as the season moves along. You notice shorter days, cooler weather, and a steady slide toward the darker winter months.
Day Length Variation
In September, you still get pretty long days—about 13 hours of daylight. By October, daylight drops to around 10 hours. When November rolls around, you’re looking at just over 8 hours.
This steady drop really changes how you plan outdoor activities or travel.
You’ll notice the shift more here than in a lot of southern places, since the city sits farther north. Each morning, the sun rises a bit later, and every evening, it sets a little earlier. Days shrink fast, week after week.
Here’s a quick breakdown:
| Month | Average Daylight |
|---|---|
| September | ~13 hours |
| October | ~10 hours |
| November | ~8 hours |
Honestly, you can’t miss how quickly the daylight disappears in Petropavlovsk-Kamchatsky once fall gets going.
Approach to the Longest Day of the Year
By fall, the city’s already moving away from the longest day, which hits in late June with nearly 17 hours of daylight. You can still sense the aftereffects of that summer peak in early September.
Days stay pretty long compared to midwinter, which always surprises me a bit. As the season moves on, the change gets more noticeable.
June’s endless daylight lingers in your memory, making the quick shift feel even sharper. By November, you get just about half the daylight you enjoyed in midsummer.
If you’re planning outdoor excursions, keep this seasonal swing in mind. Hiking or sightseeing takes a bit more planning, since daylight disappears a lot earlier than you’d expect if you’re used to lower latitudes.
