Tokyo sets record for longest consecutive rainfall streak

Tokyo has set a new meteorological record with 34 to 35 consecutive days of rainfall, the longest streak since observations began in 1886. The previous record of 33 days was held by a period in 2019.

According to the Japan Meteorological Agency, the prolonged wet weather is driven by a combination of factors, including a stationary autumn rain front, low-pressure troughs, and approaching typhoons. Masayuki Kyoda of the agency noted that the El Niño phenomenon, which raises Pacific temperatures, and a persistent high-pressure system have contributed to these unusual patterns.

The heavy rainfall has had significant local impacts. In central Tokyo, cumulative rainfall reached approximately 629 mm through late September, nearly triple the monthly average. The lack of sunlight has also been notable, with some reports indicating sunlight hours were at historic lows.

Consequences include agricultural difficulties due to excess moisture and lack of sun, as well as warnings from authorities regarding landslide risks in hilly areas. The weather has also affected daily life, impacting industries like construction and painting, and increasing demand for services like coin laundries.
