The 1929 Pacific hurricane season ran through the summer and fall of 1929. 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 hurricane" made a clockwise loop near Johnston Island between March 20 and 24. [1]
A tropical cyclone existed from May 29 to June 1. Starting from a location southwest of the Gulf of Tehuantepec, it traveled west-northwestward not far off the Mexican shore. A ship recorded its lowest known pressure of 29.21 inHg (98.9 kPa). [2]
A cyclone existed southwest of Acapulco on June 16 and 17. It produced gales, and a ship reported a pressure reading of 29.66 inHg (100.4 kPa). [3]
On August 2, a tropical cyclone formed near the Mexican coast. It eventually became a hurricane, and was last seen on August 6. The lowest pressure reported in association with this system was 28.80 inHg (97.5 kPa). [4]
On August 21 and 22, a ship encountered a possible tropical cyclone at a location far from land and almost in the central Pacific basin. The lowest pressure reported by a ship was 29.42 inHg (99.6 kPa). [4]
On August 28, this cyclone moved along the coast, and passed over the southern tip of the Baja California Peninsula around August 31. [4]
On September 10, a tropical cyclone formed in the Gulf of Tehuantepec. It moved along the coast, and was a hurricane by September 13. [5] It moved along the Pacific side of the Baja California Peninsula, and became a remnant off its northern coast on September 16. [6] Its remnants subsequently moved inland, and dissipated around September 18. The lowest pressure measured in association with this tropical cyclone was 28.28 inHg (95.8 kPa). [5]
This tropical cyclone inflicted gale or hurricane-force winds along parts of the coast of Mexico, including Manzanillo, Acapulco, and Mazatlán. [7] On September 18, its remnants caused rain of up to 4 inches (100 mm) in mountainous parts of Southern California. [8] An unseasonal warming was also attributed to this cyclone. It was also responsible for the strongest September winds ever recorded in San Diego up to that time. [9]
Somewhere between Manzanillo and Acapulco, a tropical cyclone might have existed on September 19. [10]
On September 23, a tropical cyclone was located southeast of the Gulf of Tehuantepec. It was last observed the next day. A ship reported a pressure of 29.56 inHg (100.1 kPa). [10]
In March 20 until March 22, there is a cyclone of "near tropical in nature" west of Hawaiian Islands, and with pressures as low as 29.18 inHg (98.8 kPa). It is unknown whether that cyclone is a tropical cyclone or subtropical cyclone. [11]
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 1933 Pacific hurricane season ran through the summer and fall of 1933. 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 1932 Pacific hurricane season ran through the summer and fall of 1932. 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 1931 Pacific hurricane season ran through the summer and fall of 1931. 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 1930 Pacific hurricane season ran through the summer and fall of 1930. 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 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.
The 1928 Pacific hurricane season ran through the summer and fall of 1928. 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 1926 Pacific hurricane season ran through the summer and fall of 1926. 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.
