The 1964 typhoon season was the most active Pacific typhoon season on record. All months between and including May and November were featured an above-average number of typhoons relative to the 1959–1976 period. The China Meteorological Administration (CMA), Hong Kong Observatory (HKO), Japan Meteorological Agency (JMA), and Joint Typhoon Warning Center (JTWC) each maintain tropical cyclone databases that include their respective intensity and path analyses for 1964, resulting in disparate storm counts and intensities. Total tropical cyclone counts for the 1964 season include 40 from the CMA, 34 from the JMA, and 52 from the JTWC (including 7 considered "suspect cyclones"). There were more named storms in the northwestern Pacific in 1964 than in any other year or in any other basin.
