wind-speed

The strongest surface wind gust ever officially recorded was 408 km/h on Barrow Island, Australia, during Tropical Cyclone Olivia in 1996. But the answer changes if you mean one-minute sustained tropical cyclone winds, tornado winds, jet stream winds, or winds measured away from Earth's surface. This guide explains the real records, why they differ, and how meteorologists verify wind extremes.

On April 10, 1996, an automated anemometer on Barrow Island off the northwest coast of Australia measured a three-second wind gust of 408 km/h (253.5 mph) during Tropical Cyclone Olivia — the highest surface wind speed ever officially recorded on Earth. Tornadoes have exceeded even that. A hailstone in South Dakota weighed 878 g (1.94 lb). A Venezuelan lake generates up to 1,600 lightning bolts per hour, every night, for 300 nights per year. These records are not flukes. Each one follows from specific, explainable atmospheric physics.
