Fall in Nagoya really marks a shift from the hot, sticky summer into something cooler and way more comfortable. Daytime temperatures drop off pretty steadily—from around 31°C (87°F) in early September to about 14°C (57°F) by late November.
The air doesn’t feel as heavy since humidity drops, and the skies clear up a bit, so you get more crisp, pleasant days to spend outside.
Rain still pops up fairly often at the start of the season, especially in September, but you’ll notice it easing up as autumn rolls on. By November, rainfall is lighter, skies look clearer, and the weather settles down.
This change makes autumn one of the best times to wander through the city’s parks, check out cultural spots, or just eat your way through food festivals.
Shorter days and cooler evenings slow things down, but you’ll still find conditions comfy enough for sightseeing. With mild afternoons, lower humidity, and fewer rainy days as the season goes on, fall in Nagoya feels both practical for travel and rewarding if you like being outdoors.
Overview of Fall Weather in Nagoya
Fall in Nagoya means temperatures steadily drop, humidity slips away, and rainy days become less common compared to summer. You’ll notice shorter daylight hours, chillier evenings, and clearer skies as autumn moves forward.
Typical Fall Climate Characteristics
During autumn, Nagoya’s daily highs start at about 87°F (31°C) in early September and slide down to 57°F (14°C) by late November. Lows fall even faster, going from the mid-70s°F (24°C) to the low 40s°F (6°C).
Humidity drops quickly. September days often feel muggy, but by November, the air turns much drier. That shift makes it way more pleasant for walking, sightseeing, or just being outdoors.
Rainfall drops off, too. September is the wettest month of fall, with over 6 inches (150 mm) of rain on average. By late November, monthly rainfall falls to less than half that.
Skies clear up as the season goes. Cloud cover drops from about half the time in September to less than a third by November, so you get more sunny or partly cloudy days.
How Fall Differs From Other Seasons
Compared to summer, fall in Nagoya feels cooler, less humid, and you get fewer storms. Summer brings heat, frequent rain, and the threat of typhoons, but autumn settles into milder, more stable weather.
Winter, on the other hand, gets a lot colder and drier. January’s average highs hang around the mid-40s°F (7°C), and nights can get close to freezing. Snow rarely shows up in the city, but you’ll definitely feel the chill compared to autumn’s milder air.
Spring comes with warming temps and a bit more rain, though the humidity isn’t as bad as in summer. Fall stands out by heading in the opposite direction—temperatures keep dropping, and things get clearer and drier.
If you’re traveling, autumn often feels like the sweet spot—not too hot, not too cold, and with fewer weather headaches than summer or winter.
Key Weather Patterns in Autumn
Several patterns shape Nagoya’s autumn. The temperature decline stays steady, with both highs and lows dropping each month. By late November, you’ll probably want a jacket even during the day.
Rainfall patterns shift fast. September sometimes gets heavy rain, often tied to the tail end of typhoon season. By October and November, storms fade, and rain gets lighter and less frequent.
Wind direction changes too. Early in fall, winds come from the south, bringing warm air. By late September, northerly winds take over, bringing in cooler, drier air.
Daylight shrinks by nearly three hours from September to November. Sunsets come earlier, mornings start later, and that definitely affects your outdoor plans.
Water temperatures along the coast cool off, too, dropping from about 80°F (27°C) to 65°F (18°C). That’s a pretty clear sign summer’s over.
Average Daytime Temperature Trends
Nagoya’s fall brings a steady drop in daytime warmth, shifting from late-summer heat to those cool, crisp afternoons by season’s end. You’ll get shorter days, cooler nights, and less sticky humidity, which makes being outside way easier than during summer.
Monthly Temperature Changes
Daytime highs in September often hit around 87°F (31°C) at the start of the month. By the end of September, highs usually dip closer to 77°F (25°C), so it’s still warm but not as intense as August.
October cools off more sharply. Highs drop into the upper 60s°F (19–21°C), and mornings start to feel a lot chillier. By November, afternoons average 57°F (14°C), and some days barely get out of the low 50s°F.
So, expect about a 30°F decrease in daytime highs from early September to late November. Packing layers really helps, since the cooling trend doesn’t let up.
Day and Night Temperature Range
The gap between daytime highs and nighttime lows widens as fall goes on. September nights average near 74°F (23°C), so it stays mild even after sunset. By November, lows drop to 42°F (6°C), making mornings and evenings much colder.
A typical September day swings 10–15°F, but in November, the gap often hits 15–20°F. That sharper contrast later in the season means evenings can feel pretty chilly even when the afternoons are nice.
If you’re out all day, you’ll notice brisk mornings, comfortable afternoons, and then a quick cool-down in the evening. This pattern sticks around all season.
Comparison to Annual Averages
Compared to Nagoya’s yearly weather, fall temperatures sit right in the middle. August, the hottest month, reaches highs near 90°F (32°C), while January’s coldest days average 11°C (52°F) during the day and 33°F (1°C) at night.
Fall lands in between. September still feels summery, but by November, it’s almost like early winter. While spring warms up slowly, fall cools down fast—nearly 3°F lost each week.
This seasonal shift makes fall one of the most transitional times of year. You go from summer-like days to near-winter in just three months, which feels like a quick change compared to other places.
Rainfall and Humidity During Fall
Rainfall drops in Nagoya during fall compared to the soggy summer, but you’ll still get your share of showers. Humidity changes a lot, too, starting off muggy in September and turning drier and comfier by late November.
Monthly Precipitation Levels
Rainfall in Nagoya during fall drops off in a pretty clear trend. September is the wettest month, averaging about 200–210 mm of rain. That’s mostly thanks to leftover typhoons and seasonal rain fronts.
By October, rainfall falls to around 120–130 mm, and November brings even less—just 60–70 mm. This steady decline makes late fall one of the drier times of the year.
| Month | Avg. Rainfall (mm) | Seasonal Context |
|---|---|---|
| September | ~209 mm | Wettest month, typhoon influence |
| October | ~125 mm | Noticeable decrease |
| November | ~65 mm | Much drier, stable weather |
If you’re planning outdoor stuff, these changes matter. September often means you’ll need rain gear, but by November, the weather usually lets you enjoy clearer skies.
Humidity Patterns in Autumn
Humidity in Nagoya follows the same downward trend. Early fall days often see relative humidity above 70%, which feels heavy with temperatures near 30°C.
By October, humidity drops into the 60–65% range, making things more comfortable. Come November, levels often fall to 55–60%, so the air feels much drier.
Lower humidity also means better visibility and less of that sticky feeling you get in summer. So, September still feels a bit tropical, but by late fall, the air turns crisp and refreshing.
Rainy Days Frequency
The number of rainy days drops as fall goes on. In September, expect about 17–18 days with measurable rain. These showers can be quick or last a while.
October averages 12–13 rainy days, showing a real shift toward steadier weather. By November, you’ll see just 9–10 days of rain, making it one of Nagoya’s driest months.
This pattern really helps with planning. September might force you to be flexible, but November is a lot more reliable for outdoor sightseeing or day trips.
Average Wind Speed in Autumn
In autumn, wind speeds in Nagoya shift as the season moves from late summer’s stillness to the breezier conditions of early winter. September brings light winds, but they pick up a bit through October and November as cooler air starts to roll in.
Monthly Wind Speed Variations
September’s average wind speed usually sits near 2 meters per second (about 4.5 mph). Things stay pretty calm, especially compared to spring’s stronger gusts. High humidity and frequent rain stick around during the last stretch of typhoon season.
Winds get a little stronger in October. Speeds climb to about 3 meters per second (around 6.7 mph). The air dries out, and breezes become more noticeable, especially if you’re near the coast or in open areas. These winds help clear out humidity and make being outside a bit more enjoyable.
By November, the seasonal change is obvious. Average speeds stay near 3 meters per second, but gusts can feel stronger as cold fronts arrive from the north. This marks the approach of winter and brings a crisp feel to the city.
Wind Patterns and Their Impact
Nagoya’s autumn winds usually come from the north and northwest as continental air moves over Japan. These patterns show up more often later in the season, pushing out the southerly summer breezes. The new wind direction cools things down and makes evenings feel brisk.
Day-to-day, these winds rarely mess with travel or outdoor plans. Speeds stay moderate, and you won’t see the strong gusts that spring sometimes brings. If you’re near rivers, open land, or the coast, winds pick up a bit, but in the city, tall buildings block some of it.
For visitors, October and November’s steady breeze feels refreshing. It drops humidity, clears the sky, and makes walking or cycling nicer. September still brings calmer, damper air, but later months mix cooler temps with gentle winds that highlight the season’s change.
Sunshine and Daylight Hours
In fall, Nagoya’s sunshine and daylight both change noticeably. The days get shorter compared to summer, but you still get enough sun to enjoy being outside.
Average Daily Sunshine
September usually brings 5.5 to 6 hours of sunshine per day. October bumps that up a bit to 6 to 6.5 hours, then November drops back down to about 5 hours. These numbers show the balance between lingering summer warmth and the clouds that come with autumn.
October tends to have the sunniest days, thanks to less rain than September. That makes it a great month for sightseeing, walks, or just soaking up autumn colors.
By November, skies often stay clear, but the sun spends less time above the horizon. Even with shorter days, the lower humidity and cooler air make the sunshine feel crisp and pretty nice.
| Month | Avg. Sunshine (hrs/day) | Notes |
|---|---|---|
| September | 5.5–6.0 | Rainiest fall month, humid |
| October | 6.0–6.5 | Drier, clearer skies |
| November | ~5.0 | Shorter days, crisp air |
Changes in Daylight Duration
Daylight hours in fall just keep shrinking. In early September, you get about 12.5 hours of daylight each day.
By late October, that drops closer to 11 hours. By the end of November, you might only see about 10 hours.
So, you’ve got less time for outdoor stuff in the evenings. If you want to go sightseeing, you’ll need to start earlier to catch the best of the daylight.
The shift sneaks up on you, but you’ll notice it. Sunsets move from around 6:15 pm in September to about 4:45 pm in late November.
Mornings don’t help much either, since sunrise goes from 5:30 am to nearly 6:30 am as fall goes on.
Shorter days and cooler air really set the mood for the season. You might even find those early sunsets make Nagoya’s autumn colors pop, especially in the city’s parks and gardens.
Travel Tips for Visiting Nagoya in Fall
Nagoya’s fall temperatures feel mild during the day, but they drop fast after sunset. You’ll find plenty of outdoor festivals and cultural events, which make this season a fantastic time to discover the city.
What to Pack for Autumn Weather
Daytime highs usually land between 16°C and 22°C (61–72°F). Nights can get down to 8–12°C (46–54°F), so you’ll want to dress in layers.
Bring long-sleeve shirts, light sweaters, and jeans for daytime comfort. In the evenings, toss on a jacket, trench coat, or windbreaker to keep warm.
If you get cold easily, a thicker coat might be a good idea.
You’re going to walk a lot, so footwear matters. Light sneakers or casual walking shoes work best for city streets, castle grounds, and temples.
Skip heavy boots unless you’re heading out for a hike in the hills nearby.
Rain doesn’t show up all the time in fall, but you’ll probably get a quick shower here and there. A compact umbrella or a light rain jacket fits easily in your bag and can save the day.
Best Outdoor Activities in Fall
Nagoya’s autumn weather just begs you to get outside. The air feels cooler and way more comfortable than in summer, so you can wander around without breaking a sweat.
A few highlights:
- Nagoya Castle: You’ll spot the golden shachi ornaments up close, and samurai re-enactors often put on open-air shows.
- Osu Kannon Temple: Step into this historic spot, then get lost in the Osu Shopping District, which has more than 1,000 quirky little shops.
- Nagoya Festival: Parades fill the streets in mid-October, with traditional costumes, floats, and live music everywhere you look.
If you’re into nature, parks and gardens nearby burst with colorful maple and ginkgo leaves. Photographers usually head out early in the morning, since the light’s softer and you won’t bump into as many people.
Evenings get lively, too. Food stalls pop up and you’ll catch folk performances here and there. Toss a light jacket in your bag so you can stick around and soak up the atmosphere after sunset.
