Jan · Feb
Mild but humid winter that can feel chilly
Avg low 2-3°C / high 8-11°C · Rainy days: 6-8 per month / rainfall around 50-70 mm
- • Definitely milder than Seoul, but wind off the sea can make it feel colder than the numbers suggest.
- • Snow that piles up is rare, but humid air can give a “clammy” chilly feeling.
- • Indoor heating is weaker than in Korea, so you may keep your coat on in cafés and restaurants.
Suggested outfits
- · Thick coat or padded jacket
- · Thermal inner and knitwear
- · Scarf and gloves
A note for travelers
If you expect “Busan-like mildness” and pack too lightly, you may feel surprisingly cold—prepare at least one full winter outfit.
Mar · Apr
Spring with cherry blossoms and perfect walking weather
Avg low 6-11°C / high 14-20°C · Rainy days: 8-10 per month / rainfall around 90-120 mm
- • Early March can still feel chilly, but mid-March onwards is distinctly spring-like.
- • During blossom season, places like Ohori Park and Maizuru Park offer great views.
- • Temperature swings are large, so light by day and warmer by morning/evening is a good rule.
Suggested outfits
- · Trench or light coat
- · Shirts, sweatshirts, or light knits
- · Comfortable sneakers
A note for travelers
Blossom spots and nearby cafés and yatai get busy, so try blossoms in the morning and yatai in the evening for smoother flows.
May · Jun
Start of the rainy season and rising humidity
Avg low 15-20°C / high 22-27°C · Rainy days: 10-12 per month / rainfall around 130-200 mm
- • May feels fairly mild, but as June approaches, rain increases due to the rainy season.
- • Humidity, more than temperature, drives fatigue, so breathable clothing is important.
- • Shoes can get wet easily even with an umbrella, so water-resistant shoes or spare socks are useful.
Suggested outfits
- · T-shirt with light shirt
- · Breathable slacks or long skirts
- · Umbrella and water-resistant shoes or sandals
A note for travelers
On rainy forecasts, pair indoor shopping around Canal City or Hakata station with café hopping as a dedicated “rainy-day plan”.
Jul · Aug
Hot, humid midsummer — a battle with humidity
Avg low 24-26°C / high 31-33°C · Rainy days: 8-11 per month / rainfall around 200 mm
- • “Feels like” temperatures above 35°C are common, and you can start sweating after only a short walk.
- • Many days see quick, strong showers that clear up again soon.
- • Strong indoor AC means big temperature differences between outside and inside, which can be tiring.
Suggested outfits
- · Very light T-shirts or tank tops
- · Linen/cotton shorts or dresses
- · Thin cardigan for indoor AC
A note for travelers
For yatai and street food, evenings after sunset are far more comfortable; use daytime for cafés and shopping.
Sep · Oct
Cooling air and comfortable autumn for walking
Avg low 17-20°C / high 24-27°C · Rainy days: 8-10 per month / rainfall around 130-160 mm
- • Early September still has a summer feel, but nights grow cooler.
- • October offers many days where a T-shirt plus light cardigan is perfect for walks.
- • Typhoon paths can bring wind and rain, so check forecasts before traveling.
Suggested outfits
- · T-shirt with light outer layer
- · Light knits or long-sleeve tees
- · Comfortable sneakers
A note for travelers
If you want to combine Fukuoka with nearby spots like Dazaifu or Itoshima, October balances activity and fatigue best.
Nov · Dec
Between autumn foliage and early winter — subtly chilly season
Avg low 6-9°C / high 13-16°C · Rainy days: 7-8 per month / rainfall around 60-90 mm
- • Around mid-November, foliage peaks and cool, clear air makes walking pleasant.
- • December feels like the start of winter with cold mornings and evenings, but no severe deep freezes like in Seoul.
- • Heating in shops and underground areas is modest, so you may stay in outerwear for long periods.
Suggested outfits
- · Thick jacket or coat
- · Knits or sweatshirts
- · Scarf or muffler
A note for travelers
Because yatai culture means sitting outside at night, pack enough layers for upper-body warmth.
