The climate of Fukuoka
The record high among the Fukuoka Prefecture stations covered here is 39°C, observed on August 26, 2026, in the city of Fukuoka, facing the Genkai Sea. Before that, the highest among them was 38.3°C, recorded both in the city of Fukuoka on July 20, 2018, and at Iizuka on August 20, 2020, so the coast and the interior had shared the top for 6 years. The top 3 heat records are from July and August at the height of summer, and right below them are years when the heat reached into September at the start of autumn.
The difference in normal summer values is only 0.4°C, but in winter the stations differ in character. Over the 30 years of 1996–2025, the average January minimum is 3.8°C in the city of Fukuoka against 1.2°C at Iizuka, a gap of 2.6°C. Iizuka observed -9.7°C on January 19, 1945, the prefecture's record low. The city of Fukuoka's record low is -8.2°C on February 5, 1919.
The nearness of the sea shows in night temperatures too: the average August minimum is 25.8°C in the city of Fukuoka and 24.1°C at Iizuka. For rain, Iizuka recorded 338 mm on July 6, 2018, and the city of Fukuoka 307.8 mm on June 25, 1953. The month with the lowest share of days with less than 1 mm of precipitation is July at Iizuka, at 60.9%, and June in the city of Fukuoka, at 61.6%, so the weight of the rainy season shows in the numbers.
Record values in this description are based on data collected as of September 2026, and the normal statistics on the 30 years 1996–2025.

Annual mean temperature (1996–2025)
The yearly average of the daily mean temperature (the line is broken in years with many missing values). Observing conditions at Fukuoka changed on December 4, 2007; June 25, 2008; February 18, 2010; February 14, 2025 (for example, a relocation or new instruments), so the statistics may not be continuous across those dates.
The normals listed here are averages over the 30 years from 1991 to 2020. They are fixed values that stay the same until the next revision of the normals, and they show how warm or cold that month usually is in that area.
