Nagasaki in January

Cold harbour wind, with clear and grey days mixed. In years when Lunar New Year comes early, lanterns can start going up in Chinatown at the end of the month for the Lantern Festival. It is windy near the port, so a hat that covers your ears helps.

A cool month: highs of 11°C, lows of 4°C. Sweaters came out of the suitcase and mostly stayed on. Showers came now and then, about 8 rain days in all, and most of the month stayed dry. Counts moved moderately between years: 3 in 2019, 14 in 2009.

Frost touched 2 nights of the month on average, enough to glaze puddles and shaded steps at first light. January 2020 averaged 12.8°C by day, 2.0°C above the 20-year mean. Cold snaps happened: the record low for January was −3.4°C, set in 2011.

Typhoons i No tropical storm passed within 300 km in this month over the last 20 years. Typhoons: May and July to October
