What is the Köppen climate of Tokyo, Japan?

The Köppen climate of Tokyo, Japan, is Cfa. This code identifies a humid subtropical climate, with hot, humid summers, relatively mild winters, and no true dry season.

Tokyo’s location on the Pacific side of Japan brings substantial rainfall and strong seasonal contrasts. August is the warmest month, averaging about 26.9°C, while January averages about 5.4°C. Summer humidity is high, and the city can be affected by typhoons; winter is cooler and drier, with occasional snowfall but no persistent snow cover in most of the city.

The “f” in Cfa means precipitation is sufficiently distributed throughout the year, distinguishing Tokyo from Cwa climates, which have a clearly dry winter. The “a” indicates a hot summer. Tokyo’s classification applies to the former city and most of Tokyo prefecture, but the prefecture’s distant islands have different tropical classifications, so “Tokyo” must be understood as the main urban region in this quiz.
