Average Seasonal Temperatures Across Northern and Southern Japan

Northern Japan (Hokkaido, Tohoku)

Northern Japan experiences four distinct seasons with significant temperature ranges:

• Winter (December–February): 25°F to 35°F (-3°C to 2°C) – Cold, snowy conditions prevail, especially in Hokkaido.
• Spring (March–May): 40°F to 60°F (4°C to 16°C) – Gradual warming; cherry blossoms bloom late April to May.
• Summer (June–August): 65°F to 75°F (18°C to 24°C) – Mild summers; cooler than southern regions.
• Autumn (September–November): 50°F to 65°F (10°C to 18°C) – Crisp, clear weather with vibrant foliage.

Southern Japan (Kyushu, Shikoku, Okinawa)

Southern Japan enjoys a subtropical climate with milder winters and hotter, more humid summers:

• Winter (December–February): 40°F to 50°F (4°C to 10°C) – Mild, rarely freezing; Okinawa remains warmer.
• Spring (March–May): 50°F to 65°F (10°C to 18°C) – Pleasant; early cherry blossoms in March.
• Summer (June–August): 75°F to 85°F (24°C to 30°C) – Hot, humid; rainy season (tsuyu) in June/July.
• Autumn (September–November): 65°F to 75°F (18°C to 24°C) – Warm, decreasing humidity; typhoon risk early autumn.

These averages represent broad regional trends; microclimates, elevation, and coastal proximity create local variations. Japan's long north-south archipelago spans over 20° of latitude, producing this striking climatic diversity.
