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.

Hail shattered the maize corn grains without pity. Successive earthquakes at quick intervals further terrorized the populace."

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 .
