Weather in Fukuoka in March

Shoulder season. March sits in between. You will get good days and you will lose some. Highs sit at 14.7 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

March ranks 6 of 12 in Fukuoka: past the worst of the year but short of October, which is the month to book if the dates are open.

Rain on 11 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 14.7 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest March day reached 24.1 °C and the coldest night fell to -2.1 °C, and the wettest single day dropped 60 mm — roughly 51% of the month's rain in one day.

March is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest March on record still delivered 196 mm against 61 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 118 mm average is a reasonable planning figure, not a promise.

Wind is light at 5.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, which at 14.7 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How March sits in the year

The month is on the way up: 3.5 °C warmer than February, and April adds another 5.2 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

11.9 hours of daylight, gaining 1 hours across the month. That is between Fukuoka'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 14.4 °C in March — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 27.4 °C in August and bottoms out at 14.4 °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

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

March in Fukuoka versus nearby

If Fukuoka 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. Hiroshima is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: March is a compromise. October is 21 points better and is what Fukuoka is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
