1937 Pacific typhoon season

In 1937, there were 25 tropical cyclones across the northwestern Pacific Ocean, north of the equator and west of the International Date Line. There were at least 17 typhoons, which are tropical cyclones with sustained winds of at least 119 kilometres per hour (74 miles per hour). The year's strongest observed typhoon was in November, when a barometer in the eastern Philippines observed a barometric pressure of 951 mbar (28.1 inHg). The typhoon was the second in a series of three to make landfall in the eastern Philippines between November and December, resulting in a collective 289 fatalities, as well as causing an outbreak of dysentery. However, the deadliest storm of the season was a typhoon that struck Hong Kong in September, killing at least 11,000 people, mainly fishermen.

Tropical activity during the year began on May 10, when a tropical cyclone was observed in the South China Sea. In June, the season's first typhoon struck the Philippines, resulting in four fatalities, including three from a shipwreck. There were three tropical cyclones in July, the first of which hit China's Hainan island. The next typhoon moved through Japan, flooding thousands of houses. Another typhoon in July resulted in 28 deaths in the Philippines, before it weakened and struck eastern China near Shanghai. A series of eight tropical cyclones occurred in August, including one storm that dropped rainfall during the Battle of Shanghai amid the Second Sino-Japanese War, as well as a typhoon in the Korean peninsula that killed 130 people. Another typhoon moved across Japan in September, causing 70 fatalities. The final storm of the season dissipated on December 14 in the South China Sea.
