The 1927 Pacific hurricane season ran through the summer and fall of 1927. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land.
A tropical cyclone moved along the coast of Mexico from June 14 to 18. It had gale-force winds and a minimum reported pressure of 29.58 inHg (100.2 kPa). [1]
A tropical storm existed off the coast of Mexico during late June. [2] The initial low pressure area formed near the Gulf of Tehuantepec on June 23, moving west-northwest near the coast into July 1. [3]
A small tropical cyclone was detected on July 1. Its lowest reported pressure was 29.56 inHg (100.1 kPa), and was moving along the coast of Mexico. [1]
A ship encountered a tropical cyclone on July 5. The ship reported a pressure of 29.70 inHg (100.6 kPa). The cyclone was moving west-northwest. [1]
On July 28, a tropical cyclone moved eastward in the Gulf of Tehuantepec. [1]
Roughly southwest of the Gulf of Tehuantepec, a tropical cyclone formed on August 7. It moved along the coast and dissipated south of the entrance to the Gulf of California on August 10. [4]
On September 6, a tropical cyclone formed south of the Gulf of Tehuantepec. It moved along the coast, and by September 8 it was west of Manzanillo. It entered the Gulf of California on September 10, and it made landfall or dissipated the next day. The lowest reported pressure was 29.15 inHg (98.7 kPa). [5]
The tropical cyclone caused much damage and destruction. [5] The cyclone drove huge waves ashore along the coast, and destroyed rail lines linking Mexico City with the Pacific coast. [6] Some ships were also missing and presumed sunk. [7] Shipping was badly damaged. [8] Some of the ships initially reported sunk were later accounted for. [9] The worst hit areas were Manzanillo and Salina Cruz. Salina Cruz was reduced to ruins. [6] A sudden plunge in the barometer provided enough warning for emergency evacuations in those cities, which were credited with keeping the death toll below that which was initially reported. [9] In Mazatlán, one person was killed by being swept over the sea wall. [6] Acambaro, Guanajuanto was flooded. [10] In the aftermath, displaced refugees attempted to cross the border and enter Nogales, Arizona. [11]
A "tropical hurricane" formed well southwest of Mexico on September 7, dissipating on September 10. [3]
A tropical cyclone formed in the Gulf of Tehuantepec on September 11. It moved northwest and was last observed on September 12. [5]
In the Gulf of Tehuantepec, a tropical cyclone was detected on September 25. It moved along the coast and was last seen on September 30. The lowest reported pressure was 29 inHg (98 kPa); a ship reported a maximum windspeed of 125 miles per hour (201 km/h; 109 kn). [5]
A tropical depression existed south of Acapulco on October 19 and 20. [12]
Tehuantepecer, or Tehuano wind, is a violent mountain-gap wind that travels through the Chivela Pass in southern Mexico, across the Isthmus of Tehuantepec. It is most common between October and February, with a summer minimum in July. It originates from eastern Mexico and the Bay of Campeche as a post-frontal northerly wind, accelerated southward by cold air damming, that crosses the isthmus and blows through the gap between the Mexican and Guatemalan mountains. The term dates back to at least 1929. This wind can reach gale, storm, even hurricane force. The leading edge of its outflow may form rope cloud over the Gulf of Tehuantepec. These winds can be observed on satellite pictures such as scatterometer wind measurements, they influence waves which then propagate as swell and are sometimes observed 1,600 km (1,000 mi) away. These strong winds bring cooler sub-surface waters to the surface of the tropical eastern Pacific Ocean and may last from a few hours to 6 days.
The 1939 Pacific hurricane season ran through the summer and fall of 1939. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. However, 1939 saw a large number of storms threaten California.
A Pacific hurricane is a mature tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of 180°W, north of the equator. For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern, central, and western, while the southern Pacific is divided into 2 sections, the Australian region and the southern Pacific basin between 160°E and 120°W. Identical phenomena in the western north Pacific are called typhoons. This separation between the two basins has a practical convenience, however, as tropical cyclones rarely form in the central north Pacific due to high vertical wind shear, and few cross the dateline.
The 1940 Pacific hurricane season ran through the summer and fall of 1940. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. During this season, there is a former typhoon that crossed into central north Pacific.
The 1941 Pacific hurricane season ran through the summer and fall of 1941. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. 1941 season was the last season before Monthly Weather Review stopped publishing temporarily due to World War II.
The 1938 Pacific hurricane season ran through the summer and fall of 1938. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. However, 1938 saw an unusually active season, with numerous tropical cyclones forming in January and a hurricane struck Northern California in February, killing five people. On August 18, Cyclone Mokapu caused record August rainfall, and a record low pressure when it struck Hawaiian Islands. It brought down power lines and damages into a plantation.
The 1937 Pacific hurricane season ran through the summer and fall of 1937. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. 1937 season was mostly inactive season, as there is no known tropical cyclones in September during this season. In May, a tropical cyclone struck Acapulco, cutting that city off from the outside communication for four days, causing buildings in the city to be damaged, and caused a woman's death.
The 1936 Pacific hurricane season ran through the summer and fall of 1936. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. There are numerous damaging tropical cyclones during the season, and half of tropical cyclones during the season became hurricanes.
The 1935 Pacific hurricane season ran through the summer and fall of 1935. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. This season saw three tropical cyclones and ended early in August.
The 1934 Pacific hurricane season ran through the summer and fall of 1934. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land.

The 1925 Pacific hurricane season ran through the summer and fall of 1925. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. 1925 season was the first Pacific hurricane season that was covered in detail by Monthly Weather Review, and this season included the most intense November Pacific hurricane on record until beaten by Hurricane Kenneth in 2011.
The 1942–48 Pacific hurricane seasons all began during late spring in the northeast Pacific Ocean and the central Pacific. They ended in late fall.
