When you think of winter in Japan, you might picture heavy snow and biting winds. Hiroshima tells a different story.
Winter in Hiroshima usually feels mild, with average daytime highs around 5–10 °C (41–50 °F) and just a touch of snow here and there. If you like cool weather but not the deep freeze of northern Japan, this city is honestly a solid pick. Nights sometimes get close to freezing, but the cold doesn’t stick around for long.
You’ll see more dry days than wet ones, since winter brings the least rain all year. Sometimes there’s a bit of snow or sleet, but it melts before you know it. The air feels crisp, and the lower humidity gives you clear skies and more sunshine than you’d get in summer.
This blend of cool temps, light snow, and dry air really sets Hiroshima apart from places like Sapporo or Nagano, where winter means deep snow. If you’re after a winter that’s chilly but not punishing, Hiroshima’s climate might just be your thing.
Typical Winter Temperatures in Hiroshima
Hiroshima’s winters bring cool days and cold nights, but temps usually stay above freezing. There’s a bit of variation between December, January, and February. January, though, is always the coldest.
Monthly Average Highs and Lows
In December, highs reach about 12°C (53°F), and lows hit around 4°C (39°F). Nights can get chilly, but with a coat, daytime feels fine.
January is the coldest stretch. Highs hover around 9–10°C (48–50°F), and lows dip to about 2°C (36°F). You might see frost, but it rarely snows in central Hiroshima.

| Month | Avg. High | Avg. Low |
|---|---|---|
| December | 12°C / 53°F | 4°C / 39°F |
| January | 9–10°C / 48–50°F | 2°C / 36°F |
| February | 11°C / 52°F | 3°C / 37°F |
Temperature Trends from December to February
The seasonal shift happens steadily, not all at once. December starts off pretty mild, but mornings get a bit cooler each week.
January keeps things coldest, with highs often stuck below 10°C (50°F). Late January nights can drop to 1–2°C (34–36°F), so bundle up.
By mid-February, you’ll notice a gentle warm-up. Daytime highs creep into the low teens Celsius, and nights aren’t quite as harsh. Stick around a few weeks and you’ll feel the difference.
Notable Cold Spells
Severe winter weather almost never hits Hiroshima, but cold snaps can surprise you. Sometimes lows drop to -2°C to 0°C (28–32°F), especially inland or up north.
Late January usually brings the coldest days. Highs might not even reach 7°C (45°F), and frosty mornings become pretty common.
The city center doesn’t see much snow, but the mountains around Hiroshima do. If you’re heading up there, pack heavier winter gear and expect colder air.
Precipitation Patterns During Winter
Hiroshima’s winters are pretty dry compared to the rest of the year, though you’ll still get some rain or even a little snow. Overcast skies show up more than in autumn, and the cooler air holds less moisture, so precipitation totals stay low.
Average Rainfall and Snowfall
Rainfall during winter is modest. December and January bring in 40–65 mm of rain, and February averages around 60 mm. It’s nothing like the downpours of summer.
Snow doesn’t really stick in the city center, thanks to its low elevation and being near the coast. When it does snow, it’s usually light and melts in no time. The northern mountains, though, can get several centimeters.
Don’t expect deep snow in Hiroshima city. You might see a dusting once or twice in a colder winter, but rain is way more common than snow for most visitors.
Frequency of Wet Days
Even though total rainfall is low, you’ll still get more wet days than you might think. Winter months average 15–19 days with some kind of precipitation.
Most of these are just light rain or drizzle, not heavy storms. Snow falls on a handful of days, but it almost never sticks around.
So, you’ll probably deal with damp weather now and then, even if it doesn’t rain much. Carrying an umbrella is smart since showers can pop up unexpectedly.
Humidity Levels
Winter humidity drops compared to summer, but it’s still there. Relative humidity sits between 60% and 70%, which isn’t bad compared to Japan’s rainy season.
Cooler air keeps the humidity from feeling heavy, but indoor heating can dry things out. If you’re sensitive, bring some moisturizer and lip balm.
Outside, the mix of cool temps and moderate humidity gives you that crisp, brisk winter feeling. Walking around is comfortable if you’re dressed warmly and ready for a bit of dampness.
Winter Weather Characteristics
Hiroshima’s winters are cool and mostly dry, with light winds, limited daylight, and the occasional frost. You’ll notice the city center feels different from the hills, where it’s colder and a bit windier.
Wind Conditions
Winds in Hiroshima during winter stay light to moderate. Average speeds range from 6 to 12 km/h (4–7 mph), so strong gusts are rare in the city. The mountains help block out the harsher winds.
Winds often change direction with passing weather systems. Cold fronts from the northwest can bring brief, stronger breezes, but they lose strength by the time they reach the inland sea.
In winter, winds mostly blow from the northwest and north, bringing cooler air. Along the coast, you might feel a breeze from the Seto Inland Sea, but it’s usually mild.
Since winds aren’t strong, they don’t mess with travel much. Still, they can make chilly mornings feel even colder, so don’t let the thermometer fool you.
Sunshine Hours
Hiroshima gets more winter sunshine than a lot of northern Japanese cities. On average, you’ll see 4 to 5 hours of sunshine per day in December and January. Clouds roll in now and then, but you won’t get endless gray skies like along the Sea of Japan.
Daylight hours shrink, with the sun setting before 6:00 p.m. in midwinter. It can limit your time outdoors, but clear skies make things feel brighter and more cheerful than summer’s muggy haze.
Sunny days become more common in February, as the weather shifts toward spring. Late winter is honestly a great time to go sightseeing—much better than the darker weeks of January.
Frost and Ice Occurrence
Frost shows up a lot on winter mornings, especially in January. Nighttime lows often reach 1–2°C (34–36°F), so you’ll see ice on cars and shaded paths.
Snow barely makes an appearance in the city, averaging just a few centimeters each year. Still, you might catch a bit of snow or sleet a few times between December and February. The northern hills get more, but it doesn’t really affect the city.
Watch out for icy spots on bridges and shady roads. Even when there’s no snow, temps near freezing can make surfaces slick. This happens more after clear nights, when frost forms quickly.
If you’re staying downtown, you’ll probably see more frost than snow, so shoes with good grip are more useful than heavy boots.
Comparing Hiroshima’s Winter to Other Japanese Cities
Hiroshima’s winters are milder than a lot of Japan, with little snow and moderate temps. You’ll notice the difference if you compare it to other places—cold, rain, and wind all play out differently, which can really affect your plans.
Differences with Northern Japan
Head north to Sapporo or Aomori, and you’ll get slammed with winter. Up there, heavy snow falls as cold Siberian winds meet moist air from the Sea of Japan. Snow piles up for weeks, and temps stay below freezing.
Meanwhile, Hiroshima’s average January temp is about 4°C (39°F), while Sapporo sits around -4°C (25°F). Snow in Hiroshima is rare and melts fast, but northern cities need snowplows and winter tires just to get by.
Northern Japan also gets more wind chill. Stronger winds and long stretches of clouds make it feel even colder. Hiroshima, protected by the sea and mountains, dodges a lot of this, so you get more sun and less biting wind.
Comparison to Tokyo and Osaka
Tokyo and Osaka have a humid subtropical climate like Hiroshima, but their winters aren’t quite the same. Tokyo is a bit warmer, with January averages around 6°C (43°F) compared to Hiroshima’s 4°C (39°F). Snow is rare in both cities, though Tokyo might see flurries once or twice.
Osaka’s winter feels pretty similar to Hiroshima’s, but it’s drier. Hiroshima’s average January rainfall is about 39 mm, while Osaka gets less. So, you’ll probably run into more damp days in Hiroshima.
Winds differ too. Tokyo gets stronger winter winds, averaging 13–15 km/h, while Hiroshima’s are calmer at 7–8 km/h. That makes Tokyo feel colder than the numbers suggest, while Hiroshima’s light breezes make it nicer to walk around.
Impact of Winter Weather on Daily Life
Winter in Hiroshima brings cooler temps, shorter days, and more clouds. You’ll need to adjust how you dress, get around, and plan your days.
Clothing Recommendations
Plan for daily highs in the low 50s °F (10–11°C) and lows in the mid-30s °F (1–3°C). January is the coldest month, and even though snow is rare, the damp air can make it feel chillier than you expect.
Layering is your friend. A light to medium winter coat, sweaters, and long sleeves work for most days. If you’re out at night, add a scarf, gloves, and hat for warmth.
Pick water-resistant shoes since winter brings steady rain, especially in February. Streets can get slick, so good traction matters. Don’t forget a compact umbrella—showers are frequent.
Indoors, lighter layers are better since most places are heated. That way, you can peel off a layer or two when you step inside.
Travel Considerations
Winter weather rarely causes big travel problems in Hiroshima, but planning ahead helps. Rain is more common than snow, and wet streets can slow you down if you’re walking or biking. Public transit runs smoothly, but buses and trams might get crowded during rush hour.
If you’re driving, watch out for icy roads in rural or high-up areas outside the city. Snow tires or chains might be required up there, even if downtown is clear.
Daylight is short in December and January, with sunset before 5:30 PM. It’s best to plan outdoor activities earlier. By late February, longer days make evening outings easier.
Carrying a small umbrella or rain jacket keeps you dry if you get caught in a sudden shower. If you’re planning day trips, check the forecast—weather can change quite a bit between coastal Hiroshima and the inland mountains.
Notable Winter Events and Seasonal Highlights
Winter in Hiroshima feels a lot quieter than the busy spring or summer. You get to enjoy cultural events, tasty local food, and seasonal scenery without fighting crowds.
The Hiroshima Dreamination festival stands out as one of the most popular highlights. Streets and parks burst into color with thousands of LED lights, which makes for a really relaxing way to end a day of sightseeing. This event usually sticks around through most of winter.
Food in winter feels special here. Hiroshima’s oysters reach their peak in freshness, and honestly, they’re delicious. Local restaurants serve up oyster hot pots, grilled oysters, and even oyster okonomiyaki, so you’ll get a true taste of the region.
You might want to check out Miyajima Island for a different vibe. The crowds thin out, and the Itsukushima Shrine looks especially striking in the crisp air. Hiking trails stay open, but you’ll want to bundle up since it gets chilly.
If you’re into outdoor activities, head north in Hiroshima Prefecture for skiing and snowboarding. The city doesn’t really get much snow, but mountains nearby give you a chance to hit the slopes without traveling far.

| Highlight | What to Expect |
