Questions about August 20

What is the strongest storm on record on August 20?

Of the storms active on August 20, Typhoon Nina (1953) had the highest peak wind recorded by a U.S. agency: 160 kt (184 mph), 1-minute sustained (JTWC). That is the storm's peak over its whole life, which may fall on another day. Agencies that average wind over 10 minutes report lower numbers for the same storm.

Has a storm ever made landfall on August 20?

Yes. 40 storms on record came ashore on August 20. The most recent was Hurricane Hilary (2023): landfall near San Fernando, Baja California, Mexico (tropical storm). Some coast crossings are estimated from the track, and each one is labelled.

How many storms were active on August 20?

469 storms on record were active on August 20, in 153 different years from 1851 to 2026. The count uses calendar dates in UTC and covers every ocean basin in NOAA's IBTrACS archive and the National Hurricane Center's HURDAT2.

Each wind speed keeps the agency that recorded it and its averaging period; nothing is converted between agencies. A missing value is shown as not recorded, never as zero. Storms that may still have been active when the archive was updated are left out.
