Weather in Hiroshima in November
Japan · 20-year averages, November
A good month. November is a solid month to be in Hiroshima. Highs average 16.8 °C, lows 7.4 °C, and rain falls on 10 days — nothing in the month is working against you.
November ranks 4 of 12 in Hiroshima: past the worst of the year but short of October, which is the month to book if the dates are open.
Rain on 10 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.8 °C days and 7.4 °C nights; the spread matters more here than any single number.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest November day reached 25.2 °C and the coldest night fell to -1 °C, and the wettest single day dropped 46 mm — roughly 58% of the month's rain in one day.
November is moderately variable: 17 mm in the driest year against 177 mm in the wettest, around an average of 79 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.
Wind is light at 7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.
How November sits in the year
The month is on the way down: 6 °C cooler than October, with December dropping another 6.2 °C. The first week and the last are not the same trip.
Daylight in November
November sits at the dark end of Hiroshima's year — 10.4 hours of daylight against 14.4 at midsummer, losing 0.8 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
Sea temperature
The sea sits at about 19.9 °C in November — swimmable, but it takes a moment to commit. The sea peaks at 26.9 °C in August and bottoms out at 12.9 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
November in Hiroshima versus nearby
If Hiroshima is one option among several, the nearby comparison is worth making. Kitakyushu is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Fukuoka is close enough to be a coin toss — within a degree on temperature, 1 day less rain.
So: November works, with October the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
