November is the best month to visit Fukuoka, and it isn't close: 17.5°C / 63.5°F days, 9.6°C / 49.3°F nights, and only 3 rainy days in the entire month. April is the runner-up at 19.1°C / 66.4°F with 9 rainy days, and late October still works at 24.2°C / 75.6°F. Everything between May and September is either soaking (June collects 321.0mm / 12.6in) or brutal (July peaks at 33.4°C / 92.1°F), and August manages both at once.

November and April: the two months that actually work

November's numbers are the outlier of the whole year. 44.2mm / 1.7in of rain spread over just 3 days means roughly 27 dry days — you can plan an itinerary without a rain contingency and expect it to survive. Highs of 17.5°C / 63.5°F are walking weather in a single layer, and 9.6°C / 49.3°F nights are cool enough that you'll want a jacket after dark but never cold enough to cut an evening short.

That last detail matters more in Fukuoka than in most Japanese cities, because Fukuoka's signature nightlife is outdoors. The yatai — the open-air food stalls that set up along the Naka River in Nakasu and around Tenjin — are canvas-sided carts with stools on the pavement. In a month with 3 rainy days, you can decide at 8pm to go eat ramen on a stool by the river. In September, with 23 rainy days, that plan fails roughly three nights out of four.

April is the other strong pick and the better one if you want colour rather than dryness. 19.1°C / 66.4°F highs and 10.3°C / 50.5°F lows are the mildest comfortable pairing of the year, and 76.6mm / 3.0in over 9 days means rain arrives as discrete wet days you can plan around, not a permanent condition. Maizuru Park (the Fukuoka Castle ruins) and the Ohori Park lakeside are the walking targets here, and April's temperatures let you do them at midday without either sweating or shivering.

One tradeoff worth naming: cherry blossom in Fukuoka usually runs late March, not April, and March is a wetter, cooler month at 14.4°C / 57.9°F with 129.4mm / 5.1in over 15 days. If blossom is the reason you're going, you're accepting half the month being wet. If it isn't, April is strictly the better trip.

The months to avoid, and what makes each one bad

Fukuoka's bad season isn't one long block — it's three different problems stacked back to back.

May and June are the rain problem. May takes 272.9mm / 10.7in across 17 days and June takes 321.0mm / 12.6in across 16 days. Do the arithmetic on June: 321mm over 16 days is about 20mm per wet day, which is genuinely heavy — this is the tsuyu rainy front, and it produces grey, saturated days rather than quick showers. Temperatures are fine (26.9°C / 80.4°F highs, 20.3°C / 68.5°F lows) but "fine temperature, constant rain" is the worst possible combination for a city whose best assets — the coastline at Itoshima, the shrine approach at Dazaifu, the riverside stalls — are all outdoor.

July is the heat problem. 33.4°C / 92.1°F is the hottest month of the year, and the 25.3°C / 77.5°F low means it does not cool off overnight. Sleeping without air conditioning isn't realistic. The upside is that July is comparatively dry for summer — 74.9mm / 2.9in over 12 days, less than half of August's total — so you get heat without the wet. If you're coming for Hakata Gion Yamakasa, the float-racing festival that runs the first half of July, this is the tradeoff you're making knowingly.

August and September are both problems at once. August is 32.4°C / 90.3°F with 267.3mm / 10.5in of rain over 21 days. September is 29.9°C / 85.8°F with 192.5mm / 7.6in over 23 days — the most rainy days of any month. Read September carefully: 192.5mm spread across 23 days averages about 8mm per day, which is not a downpour. That pattern means afternoon storms and passing showers rather than all-day rain, in humid 23.5°C / 74.3°F air that never dries out. You'll be damp, not drenched, but you'll be damp constantly, and this is also the peak window for typhoons tracking up from the south. Kyushu sits directly in the path.

Shoulder season: cheaper, still fine

December and March are the two genuine shoulder months — noticeably quieter than the peak windows, and both still workable.

December gives you 12.9°C / 55.2°F highs and 5.5°C / 41.9°F lows with 88.7mm / 3.5in over 10 days. It's cold enough that you'll want a proper coat and about a third of the month is wet, but 10 rainy days is roughly the same as October's 12 and well under summer's 21–23. December is also the right month for what Fukuoka does best in cold weather: motsunabe and mizutaki hot pot, both local specialities, both far more appealing at 5°C than at 25°C. Avoid the last week if you can — New Year is a domestic travel peak and prices climb.

March is the harder sell but the better value. 14.4°C / 57.9°F is comfortable, 6.7°C / 44.1°F nights are cold, and 129.4mm / 5.1in over 15 days means half the month is wet. It's the first genuinely mild month after winter, which is why it draws blossom crowds late in the month, but the first three weeks are quiet and cheap.

Late October deserves a mention as a half-shoulder. 24.2°C / 75.6°F with 133.1mm / 5.2in over 12 days sits awkwardly between summer and the November sweet spot — the month starts warm and humid and ends feeling like November. If you can only travel in October, aim for the back half.

What each season means in practice

Winter (December–February). You'll be indoors more than out. February is the coldest month at 7.2°C / 45.0°F high and 1.5°C / 34.7°F low — colder than January's 9.1°C / 48.4°F and 3.0°C / 37.4°F, which is unusual but that's what the year measured. Pack a real winter coat, not a fleece. On the plus side, January's 43.0mm / 1.7in over 8 days is the second-driest month of the year, so cold-and-clear is a common combination. This is the season for Dazaifu Tenmangu without the crowds, department-store basements in Tenjin, and hot pot every night.

Spring (March–May). Layers, and an umbrella that lives in your bag. March and April you'll want a light jacket over a shirt; by May the 22.9°C / 73.2°F highs mean short sleeves, but 17 rainy days means you should not plan a beach day at Itoshima without a fallback. Golden Week and the Hakata Dontaku festival fall in early May, which adds crowds to the rain.

Summer (June–August). Practical packing is about sweat, not warmth: breathable fabrics, more shirts than days, and something waterproof that isn't a plastic poncho you'll cook inside. With overnight lows at 25.3°C / 77.5°F in July and 25.4°C / 77.7°F in August, the day never truly resets. Plan mornings and evenings outdoors and put the air-conditioned things — Canal City, the Kyushu National Museum, the Fukuoka Asian Art Museum — in the 1–4pm slot.

Autumn (September–November). September is still summer with more rain days. October transitions. November is the payoff: dry, mild, and the one month where you can pack light and not think about weather again. Autumn colour arrives late in Kyushu — November rather than October — which lines up neatly with the best weather.

Month-by-month

• January — 9.1°C / 48.4°F, 43.0mm over 8 days. Cold but the second-driest month; good for shrines and hot pot.
• February — 7.2°C / 45.0°F, low 1.5°C / 34.7°F. The coldest month of the year. 12 rainy days on top of it.
• March — 14.4°C / 57.9°F, 129.4mm over 15 days. Mild, half wet, cheap until blossom week.
• April — 19.1°C / 66.4°F, 76.6mm over 9 days. The best all-round month for comfort.
• May — 272.9mm over 17 days. Pleasant 22.9°C / 73.2°F ruined by the start of the rainy front.
• June — 321.0mm over 16 days, the wettest month. Skip it.
• July — 33.4°C / 92.1°F, the hottest month, but only 74.9mm over 12 days. Hot and comparatively dry.
• August — 32.4°C / 90.3°F and 267.3mm over 21 days. The worst month on both axes.
• September — 23 rainy days, the most of any month, at a humid 29.9°C / 85.8°F.
• October — 24.2°C / 75.6°F, 133.1mm over 12 days. Improving; the second half is much better than the first.
• November — 17.5°C / 63.5°F and only 3 rainy days. The best month, by a wide margin.
• December — 12.9°C / 55.2°F, 88.7mm over 10 days. Cold, quiet, good food.

FAQ

What is the single best month to visit Fukuoka?

November. 3 rainy days across the whole month, 17.5°C / 63.5°F highs, and 9.6°C / 49.3°F nights that are cool without being uncomfortable. No other month combines dryness and mild temperatures like this — the next-driest month, January at 8 rainy days, is 8.4°C colder by day.

Is Fukuoka worth visiting in summer?

Only for a specific reason. July's 33.4°C / 92.1°F with 25.3°C / 77.5°F overnight lows is exhausting, and August adds 21 rainy days to the same heat. If you're going for the Hakata Gion Yamakasa festival in early July, the heat is the price of admission and July's 74.9mm / 2.9in is the driest summer rainfall figure — that's the least-bad summer option. Otherwise, move the trip.

When is the rainy season in Fukuoka, and how bad is it?

May and June. May takes 272.9mm / 10.7in over 17 days and June takes 321.0mm / 12.6in over 16 days — roughly 20mm per wet day in June, which is heavy, sustained rain rather than passing showers. This is different from September, where 192.5mm spread over 23 days works out to lighter, more frequent bursts. June soaks you; September keeps you damp.

When should I go if I want cherry blossoms?

Late March. Fukuoka is far enough south and west that blossom typically arrives ahead of Tokyo and Kyoto. The weather cost is real — March is 14.4°C / 57.9°F with 129.4mm / 5.1in over 15 days, so plan for roughly half your days being wet, and pack a light waterproof layer plus a jacket for 6.7°C / 44.1°F evenings. If blossom isn't the point of the trip, wait two weeks for April's 9 rainy days and 19.1°C / 66.4°F instead.
