World Weather Extremes

Thousands of weather stations around the world constantly measure temperature, wind, air pressure, and precipitation to paint an accurate picture of weather from the mountains of Canada to the deserts of Australia. These stations occasionally catch some of the most extreme weather conditions ever observed.

U.S. Maximum/Minimum Temperature Extremes

The varied climates of the United States bring about tremendous temperature swings and gradients every season. Reliable weather records stretch back to the late 1800s and early 1900s for many locations throughout the country, giving us a rich history of the country's fevers and freezes. The following chart lists the all-time highest and lowest temperatures recorded in each state, as well as Puerto Rico and the U.S. Virgin Islands. Some all-time temperatures were reached more than once; only the most recent instance is shown on the chart below.

The hottest temperature ever recorded in the United States was a 134°F reading near Death Valley, California, on July 10, 1913. The country's coldest temperature ever recorded was -80°F at Prospect Creek Camp, Alaska, back on January 23, 1971. The coldest temperature in the contiguous U.S. was -70°F at Rogers Pass, Montana, on January 20, 1954.

U.S. 24-Hour Precipitation Extremes

Just like temperature extremes, precipitation extremes are a reflection of a state's diverse climate. The following records reflect the all-time highest 24-hour precipitation totals reliably observed in each state, as well as Puerto Rico and the U.S. Virgin Islands.

The highest 24-hour total ever observed in the U.S. was 49.69 inches at Hawaii's Waipā Garden between April 14–15, 2018. The highest 24-hour total in the contiguous U.S. was 42 inches in Alvin, Texas, between July 14–15, 1979. Many records across the southern and eastern U.S. fell during tropical systems; the Texas record occurred during Tropical Storm Claudette.

U.S. 24-Hour Snowfall Extremes
A map of snowfall totals along the northern Gulf Coast in January 2025.

The highest 24-hour snowfall totals happen in relatively predictable spots across the United States—mountainous states see their totals in or near mountains, while states bordering the Great Lakes see their all-time totals as a result of lake-effect snowfall.

Absent the influence of terrain or the lakes, the greatest 24-hour snowfall totals are the product of historic storms like nor'easters.

Puerto Rico and the U.S. Virgin Islands have (obviously) never recorded snow before.

The highest official total in the state of Florida was 4 inches that fell in Milton, near Pensacola, in March 1954.

However, a major snowstorm that hit the northern Gulf Coast in January 2025 produced reported totals of 8.8 inches in Milton. Pending review, this will likely be Florida's all-time 24-hour snowfall record.

International Storm-Related Extremes
An illustration of radar showing Tropical Cyclone Kerry's eye on February 21, 1979.

Largest Tropical Cyclone Eye – 56 mi. – Tropical Cyclone Kerry – Feb. 21, 1979

The eye of Tropical Cyclone Kerry grew 56 miles wide as it passed through the Coral Sea off Australia's northeastern coast. This was the first storm observed by advanced hurricane hunter aircraft in the southern hemisphere. The storm followed an erratic path and survived in the region for 27 days.

Longest-Lived Tropical Cyclone – 36 Days – Tropical Cyclone Freddy – Feb.4 - Mar. 10, 2023

Tropical Cyclone Freddy began life in the southeastern Indian Ocean off the western coast of Australia on Feb. 4. The cyclone would travel nearly 8,000 miles across the Indian Ocean, making it the longest-lived tropical cyclone on record and the second-longest cyclone track ever observed.

Heaviest Hailstone – 2.25 lbs. – Gopalganj district, Bangladesh – Apr. 14, 1986

The heaviest hailstone ever reliably observed fell during a powerful springtime supercell thunderstorm southwest of Dhaka, Bangladesh. The hailstone's diameter was not measured. The largest hailstone ever observed, though not recognized by the WMO, measured 8 inches in diameter and 18.625 inches in circumference when it was collected in Vivian, South Dakota, on July 23, 2010.

Deadliest Tornado – ~1,300 deaths – Manikganj district, Bangladesh – April 26, 1989

Bangladesh is prone to supercell thunderstorms similar to those witnessed on the U.S. Great Plains. The country's high population density and widespread poor construction can make tornadoes here a devastating disaster. This tornado reportedly caused F3 damage, grew up to a mile wide, and left 80,000 people homeless. The precise number of fatalities is unknown.

International Temperature Extremes

Northern Hemisphere Maximum Temperature – 134°F – Death Valley, California – July 10, 1913

Death Valley owes its searing temperatures to the area's desert landscape and an altitude well below sea level. While this temperature is considered official, ongoing controversy remains over its authenticity.

Northern Hemisphere Minimum Temperature – -93.3°F – Klinck AWS, Greenland – Dec. 22, 1991

This automatic weather station (AWS) resides at an altitude of more than 10,500 feet above sea level in the heart of Greenland.

Southern Hemisphere Maximum Temperature – 123°F – Oodnadatta, Australia – Jan. 2, 1960

Rural locations in Australia are routinely some of the hottest places in the southern hemisphere. A temperature of 123.3°F recorded in Onslow in January 2022 has likely broken this record from 1960, though officials haven't yet made it official.

Southern Hemisphere Minimum Temperature – -128.6°F – Vostok, Antarctica – July 21, 1983

The weather station at Vostok sits at an altitude of 11,200 feet above sea level. This all-time minimum temperature occurred in the heart of winter darkness with calm winds.

International Precipitation Extremes

Highest 1-Hour Rainfall Total – 12.0 in. – Holt, Missouri – Jun. 22, 1947

High humidity allowed a vigorous, slow-moving thunderstorm to produce an astounding 12 inches of rain over the small town of Holt, Missouri. The WMO notes that an analysis of nearby observations showed similarly extreme totals.

Highest 24-Hour Rainfall Total – 71.8 in. – Foc-Foc, La Réunion – Jan. 7-8, 1966

La Réunion is a small, mountainous island in the southern Indian Ocean. Tropical Cyclone Denise passed over the island in early January 1966. The system's deep tropical rains combined with orographic lift to produce this astonishing rainfall total over the course of 24 hours.

Highest 1-Year Rainfall Total – 1,042 in. – Cherrapunji, India – Aug. 1860-Jul. 1861

Cherrapunji, located in northeastern India, is in an ideal location to receive prolific rains during monsoon season. Humid winds blowing from the Bay of Bengal run up the nearby terrain, wringing out the excess moisture in the form of persistent and torrential downpours.

Longest Dry Period – 172 months – Arica, Chile – Oct. 1903-Jan. 1918

Arica is a port city in northern Chile's Atacama Desert. The city averages less than one-tenth of an inch of rain per year and often goes entire calendar years with no measurable precipitation. The region owes its intense aridity to the stabilizing influence of the cold Pacific Ocean and dry air blowing down the western slopes of the Andes Mountains.
