1979 Pacific typhoon season

Season statistics

• Tropical depressions: 28
• Tropical storms: 23
• Typhoons: 14
• Super typhoons: 4

Meteorological agencies that monitored and classified storms in 1979 included the Japan Meteorological Agency (JMA) and the Joint Typhoon Warning Center (JTWC); the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued local names and warnings for systems that entered the Philippine Area of Responsibility. Classification and naming conventions differ slightly among agencies, so storm counts and intensities can vary depending on the source.

Notable storms and records

The most historically significant system of the year was Typhoon Tip, which formed in October 1979. Tip remains the most intense tropical cyclone on record in terms of central pressure and one of the largest by physical size. Best‑known estimates put Tip's minimum central pressure at about 870 hPa and its cloud and wind field spanning a diameter of roughly 2,220 km. Tip's exceptional characteristics have made it a frequent subject of research into tropical cyclone dynamics and measurement techniques.

Aside from Tip, the season produced several other intense systems; four storms reached sustained intensities classified as super typhoons by the JTWC. These high‑intensity events contributed to significant weather impacts across East and Southeast Asia.

Impacts and significance

Storms during the 1979 season affected a wide area, including the Philippines, Taiwan, Japan, coastal China and the Korean Peninsula. Impacts typically included heavy rainfall, flooding, landslides, storm surge and disruption to shipping and coastal communities. The season occurred during an era when satellite monitoring and numerical forecasting were improving rapidly, and observations from large storms such as Tip informed subsequent advances in storm analysis, forecasting methods and emergency planning.
