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.
On May 30, a tropical cyclone existed in the Gulf of Tehuantepec. Shortly after its discovery, it dissipated off the coast of Guatemala. A ship reported gales and a pressure of 29.44inHg.[1]
Sometime in June, a possible tropical cyclone existed south of the Mexican coast.[2]
A possible tropical cyclone was reported between Salina Cruz and Acapulco July 7. It had moved closer to Acapulco by July 8. This system might have been associated with the remnants of the Atlantic's second tropical cyclone.[3]
Another possible tropical cyclone existed in the same area on July 29.[3]
A tropical cyclone formed in the Gulf of Tehuantepec on August. It moved along the coast, becoming at least a tropical storm, and dissipated in the Gulf of California on August 19 or 20. A ship reported an uncorrected barometer reading of 29.48inHg.[4]
A possible tropical cyclone existed on September 13. It was located well west of Manzanillo.[5]
A "tropical hurricane" was tracked well northeast of Hawaii between October 7 and 9.[6]
