Weather in Hiroshima in February

A hard month. February is a hard month in Hiroshima, and worth planning around. Highs sit at 10 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

February ranks 9 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, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 10 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 12 nights fall below freezing. Across the twenty years measured, the hottest February day reached 20.6 °C and the coldest night fell to -4.8 °C, and the wettest single day dropped 38 mm — roughly 51% of the month's rain in one day.

February is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest February on record still delivered 115 mm against 33 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 75 mm average is a reasonable planning figure, not a promise.

Wind is light at 8.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, which at 10 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How February sits in the year

The month is on the way up: 1.8 °C warmer than January, and March adds another 3.8 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in February

10.9 hours of daylight, gaining 1 hours across the month. That is between Hiroshima's extremes of 14.4 and 9.9 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 12.9 °C in February — too cold to swim without a wetsuit. 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

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

February 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, 1 day more rain. Fukuoka is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: February is a compromise. October is 32 points better and is what Hiroshima is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
