Since 1947, the Joint Typhoon Warning Center (JTWC) has classified all typhoons in the Northwestern Pacific Ocean with wind speeds of at least 130 knots —the equivalent of a strong Category 4 on the Saffir–Simpson scale, as super typhoons. Since that year, 317 super typhoons have occurred in the basin, the latest being Typhoon Sinlaku in 2026. Only two Pacific typhoon seasons have not included at least one super typhoon, which were the 1949 and the 1974 seasons. The most typhoons to have reached this intensity in a single season is tied between 1965 and 1997, with 11 becoming super typhoons.
