The following is a list of Pacific hurricanes before 1900. Data on most of the storms that formed is unavailable, however, some regions had a large enough coastal population or ship traffic to give data on the occurrence of hurricanes. Tropical cyclones in the region typically formed between May and November.
Seasons
1537
A hurricane struck Tlapa in Guerrero, Mexico, producing strong winds, hail, excessive rains, and other natural phenomena. Juan Bautista Moya, an Augustinian missionary friar in Tlapa and Chilapa viewed this tempest as "a miraculous prodigy of the Lord to confirm his missionary preaching among the indigenous people. The wind unleashed over the town of Tlaba and lashed the countryside and cottages like a giant whip. The fury of the gale uprooted and demolished trees. Hail shattered the maize corn grains without pity. Successive earthquakes at quick intervals further terrorized the populace." In this and other cases, the "earthquakes" probably entered the records because the hurricane winds shook houses and other occupied buildings, and survivors likened the shaking to that of a continuous earthquake.
1573
On 14 November, a violent hurricane lasted 3 hours at Colima City in Mexico. Earthquakes accompanied the storm, and many houses and the church building fell.
1609
A hurricane tore the cover off the church and ruined many houses in the town of Huaynamota in Jalisco, Mexico.
1832
In December 1832, according to a log from a German Merchant Marine vessel later left at Deutsche Seewarte, a tropical cyclone occurred southeast of the Hawaiian Islands; it then tracked west-northwestward, approaching 350 miles south of Ka Lae, Hawaii (island), and thence to a point near Johnston Atoll.
The new ship Japan encountered a "severe hurricane" near .
1839
On 1 November 1839, a destructive hurricane struck Mazatlán, Sinaloa, doing heavy damage to boats and watercraft; most of the twelve ships then in the harbor sunk with their crews.
1840
On November 1, a destructive hurricane did heavy damage to shipping and sunk three vessels at San Blas, Nayarit.
1842
A hurricane, between June and October, crossed the Isthmus of Tehuantepec and entered the Gulf of Mexico.
1843
I. The American barque Lark, sailing from Canton (now Guangzhou) for Valparaíso, experienced a "severe gale" on 23 September 1843 at . Afterwards, the master of this barque found necessary making port at Tahiti. The barque perhaps earlier encountered a violent typhoon off Formosa. German shipping logged this storm that day at 139°W. Someone later charted the storm to . These points suggest a trajectory toward the Big Island of Hawaii.
1847
A tropical cyclone existed On October 24 of this year.
1849
A system existed on June 21 and 22.
1850
Eight systems are recorded. I. One existed on an unknown date.
II. On or about 24 June 1850, the Joseph Butler encountered a "severe gale of wind" near , 260 miles from the coast of Mexico, which carried away her main-mast (sailing).
III. On 5 August 1850, the barque Como encountered a "severe gale" at , commencing at north and veering to west and south. She "lost sails and bulwarks and sustained much other damage." These winds suggest that the vessel traveled on the left side of the track of the storm, which passed to its northwest.
IV. On 9 September 1850, a "hurricane" at , about south of Acapulco, dismasted the Niagara.
For five hours on 11 September 1850, the Diana at experienced a "severe hurricane" from the northeast, veering to southwest; the vessel "hove on beam-ends." The veering intense wind suggests that the hurricane passed slightly northwest of the vessel, which experienced the left side. If a hurricane progressed from Niagara to Diana (and the ships logged their dates accurately), then the hurricane moved between west-northwest and northwest at .
V. On 26 September 1850, a "severe gale" at threw the Laura on her beam-ends, and she lost cargo.
