January–June

As the year began, there were two tropical depressions active across the western Pacific. The westernmost one originated on December 29, and moved through the Visayas in the central Philippines before dissipating on January 3 in the South China Sea. It produced heavy rainfall along its track. The other depression formed on December 31 in the Caroline Islands, and also dissipated on January 3.^[1]

On April 20, a tropical cyclone formed east of the Philippines island of Mindanao. The system moved northwestward, crossing the eastern Visayas and Luzon before dissipating late on April 22.^[2] The New York Times reported that seven people died during the Philippines storm.^[3]

On June 29, a tropical cyclone formed in the South China Sea. It moved northwestward, striking the Chinese island of Hainan the next day, before dissipating.^[4]

July

On July 1, a typhoon formed east of the Philippines island of Samar. The system moved to the northwest, brushing Luzon on July 4, but sparing the island from strong winds. The typhoon moved across the Luzon Strait before weakening, making landfall in southeastern China near Shantou on July 5. The storm turned northeastward and dissipated by July 6.^[5][6]

Between July 2–4, a low pressure area was located over the Caroline Islands, which organized into a depression by July 5 to the northeast of Yap. The system moved west-northwestward toward the Philippines and intensified. On July 8, the S.S. Barentsz encountered the storm, observing a minimum pressure of 970 mbar (28.65 inHg) as well as typhoon-force winds. On the next day, the typhoon made landfall in northeastern Luzon near Tuguegarao, Cagayan, where an anemometer recorded a pressure of 991 mbar (29.27 inHg). The typhoon weakened after crossing Luzon, eventually moving northward into China on July 10, where it soon dissipated. In Tuguegarao where the storm first moved ashore, two people died due to fallen trees. The typhoon sank the M.S. Marie near Palanan, killing 23 people.^[5][7][8]

On July 16, a depression was located northwest of Yap. The system moved northwestward and intensified, later turning northward through Japan's Ryukyu Islands on July 21.

October

On October 7, a trough produced two depressions – one east of the Philippines, and the other forming between Yap and Guam. The western system moved toward Luzon and intensified into a typhoon. On October 9, it made landfall in Philippines' Isabela Province. Echague recorded a minimum pressure of 976 mbar (28.818 inHg) during the typhoon's passage. The storm weakened over land and re-emerged into the South China Sea on October 11. There, it became nearly stationary, influenced by a building anticyclone to the north. On October 13, the former typhoon struck western Luzon, "very much weakened" as described by the MWR. Continuing to the northeast, the system was last observed on October 15.
