The following is a list of weather events that occurred on Earth in the year 2026.
From January 22-27, a deadly winter storm affected Northern Mexico, United States and Atlantic Canada, causing many warnings, freezing temperatures and more than 170 deaths over the area. On January 28, the storm moved out to the open Atlantic Ocean, followed by another storm which affected almost all the same regions.
On January 4, a tornado struck the Frattocchie area in Marino, Italy, after reportedly coming from the sea. 30 trees were downed, and several structures and vehicles sustained damage. The tornado was rated as an IF1.5 on the International Fujita Scale. A few days later, a small tornado event occurred in Oklahoma early on January 8, with 5 tornadoes being confirmed, one of which was rated EF2 after it tore the roof off of a house southwest of Purcell. This tornado caused one injury along its path when it rolled a semi-truck as it crossed IâÂÂ35 in the southern part of the Oklahoma City metropolitan area. That day, a significant tornado struck the town of Kalpaki, Greece. The tornado destroyed a farm killing 30,000-40,000 chickens. Two other buildings were heavily damaged, with partially collapsed walls, the tornado was rated as an IF2 tornado on the International Fujita Scale Two days later, a tornado struck the city of São José dos Pinhais, Brazil. The tornado wrecked a warehouse and damaged at least 350 homes, as well as several walls, utility poles, and trees. An estimated 1200 people were impacted, with two families being displaced and two people lightly injured. The winds reached an estimated , and the tornado rated a low-end F2.
Storm Anna caused widespread chaos at Amsterdam Airport Schiphol, particularly on January 2, 2026, where a combination of heavy snow and shifting crosswinds led to the cancellation of over 325 flights and delayed more than 635 others. The disruption at Schiphol hit KLM and easyJet hardest, with KLM alone cancelling roughly 30% of its schedule due to the airport's reduced runway capacity. The storm brought wind gusts of up to 90 km/h along the northern coast of the Netherlands. In Sweden, meteorologists recorded extreme accumulations, with up to 50 centimetres (nearly 20 inches) of snow falling in parts of central Sweden on New Year's Day and January 2, leaving thousands of households without power. In the Netherlands and Germany, the storm's tail end brought freezing rain and black ice, leading to hazardous road conditions and the deployment of specialized snow removal equipment like the Lavastorm truck on major highways. Meanwhile, in Poland, the storm's heavy snow paralyzed the S7 motorway, leaving hundreds of travelers stranded in sub-zero temperatures with traffic jams stretching up to 20 kilometres.
On January 7, extreme conditions in Victoria, Australia, allowed for a massive fire outbreak, burning over 300,000 hectares (740,000 acres), destroying over 300 structures, and resulting in one death.
From 16 January 2026, major wildfires burned in the regions of BiobÃÂo and ÃÂuble, destroying at least 800 structures, resulting in over 50,000 forced to evacuate and 21 fatalities.
In late January, much of Australia experienced a prolonged, extreme heatwave, with 12 locations recording temperatures above 49ðC, and two, Andamooka and Port Augusta reaching 50ðC on 29 and 30 January.
World Weather Attribution said that, even considering the progress of global warming, March 2026 heatwaves in Western North America were "rare events" that would have been "virtually impossible" without human-induced climate change.
In March, NASA reported that, for the second consecutive year winter arctic sea ice declined, matching the lowest level since records began in 1979.
