Narita has a humid subtropical climate shaped by its position 60 km east of Tokyo and about 10 km inland from the Pacific coast. Summers are hot and humid, winters are cool and mostly dry, and two rainy windows (the June tsuyu season and the September to October typhoon months) bring most of the year’s 1,400 mm of rainfall. This guide gives Narita weather by month with exact temperatures, rainfall, and sunshine hours, whether you are transiting the airport or staying longer. For which months to pick, see the best time to visit Narita guide.

Narita Weather by Month: Winter (December to February)
December through February is the driest, clearest stretch of the year, with 45 to 60 mm of rain per month and sunshine of 160 to 190 hours. Days reach 9°C to 11°C (48°F to 52°F) but nights fall below freezing, so pack a warm coat, especially for early-morning flights. This is a comfortable season for walking Omotesando Street and the temple grounds without the summer heat. For the temple, street food, and plane-spotting sights, see the things to do in Narita guide. Airport train fares and SIM cards are covered in the Narita travel tips and FAQ guide.
