The three largest wildfires in Colorado history occurred during 2020: The Cameron Peak Fire, the East Troublesome Fire and the Pine Gulch Fire each exceeded the acreage burned by the previous record, the 2002 Hayman Fire. However, the drought was rapidly eliminated by beneficial rainfall from Tropical Storm Isaias at the end of July. Heavy rainfall during early December saturated vegetable fields in southern Florida, resulting in crop losses, increased disease pressure on lettuce and beans, and bloom dropping in pepper and tomato plants. Global average surface temperature has risen at an average rate of 0.17F per decade since 1901 (see Figure 2), similar to the rate of warming within the contiguous 48 states.

These fires burned thousands of acres of forest and rangeland, caused evacuations, closed roads, and impacted air quality. These conditions both improved and deteriorated through winter and into spring, with the total area experiencing at least abnormally dry conditions decreasing but the total area experiencing extreme drought conditions increasing, with a small area of exceptional drought conditions developing. In addition, almost 400,000 customers lost power. Conditions improved in eastern New York but worsened in western New York and the western half of Pennsylvania. During July, the general trend across the region was worsening conditions.

The global land-only surface temperature was the eighth highest on record at +1.40C (+2.52F). For instance, in late September, topsoil and subsoil were very dry for 80 to 100 percent of Maine, New Hampshire, and Rhode Island. This is ~0.02 C cooler than in 2016, and ~0.02 C warmer than 2019. Peanuts in the Florida Panhandle were unable to be dug due to rainfall from Sally, and farmers noted that fungal disease and rotting would affect the quality of the harvest. The storm contributed to hundreds of vehicle crashes, including a pileup involving more than 65 vehicles on Interstate 80 in central Pennsylvania. Ultimately, the year ended with over 80 percent of the region in drought (D1-D4), and these conditions caused a number of impacts over the course of the year.

For the individual nations, it was the second warmest . Several other locations in central and northern California reported the second or third warmest year on record. These dry conditions were coupled with extreme heat, which helped fuel some of the largest wildfires in Colorados history. The most costly events of the year include: Hurricane Laura, the Western wildfires and the Midwest derecho. Long-term weather stations reported record warmth in Oregon, California, and New Mexico. This switch from wet to dry was so pronounced that some locations went from having a top 10 wettest year in 2019 to a top 10 driest year in 2020. Even in these areas, the wetness became a memory as drought developed and expanded in the late summer, fall, and early winter. Providence, Rhode Island, picked up 1.6 inches (4.1 cm) of snow on October 30, tying as the sites snowiest October day on record.

Annual average temperatures for the twelve Northeast states ranged from 1.9 degrees F (1.1 degrees C) above normal in West Virginia to 2.8 degrees F (1.6 degrees C) above normal in Massachusetts and Rhode Island. In May, cooler than normal conditions prevailed across every state except Texas, while precipitation was higher than normal for every state except for Mississippi. In 2021, extreme temperatures in the United States caused over 713 million U.S. dollars in economic damage. Prolonged saturated soil caused some farmers to abandon portions of their soybean and cotton fields. In addition, two weak (EF-0 or EF-1) tornadoes snapped trees and damaged houses in northern Maryland. Estimated 2021 annual value based on relationship between the January-April temperatures and annual temperatures between 1970 and 2020. Several notable widespread wind events occurred in the Northeast this year. The U.S. Drought Monitor released in June 25 showed 16 percent of the Northeast in a moderate drought and 26 percent was abnormally dry. There were at least four ground fires in Vermont this year, which is atypical. In October, Arctic sea ice concentration was the lowest value since the satellite records began. From July 29th through the 30th, Tropical Storm Isaias impacted parts of Puerto Rico, with over 9 inches (229 mm) of rainfall recorded in Juncos. Water restrictions were in place for hundreds of locations in New England, as well as some locations in New York and Pennsylvania. Many of the same locations that saw above normal and record high temperatures also experienced below normal precipitation and in some cases record dryness. Portions of Delaware, southeastern Pennsylvania, and New Jersey also saw damaging severe thunderstorms. Several nights of frost and freezing temperatures during the month caused some grass damage in pastures across northern and central Florida, while low-lying areas of pastures in southern Florida sustained flooding. A pocket of extreme rainfall occurred in the Rocky Mount-Wilson area of eastern North Carolina, with a 2-day total of 9.84 inches (250 mm) recorded at Rocky Mount-Wilson Regional Airport.
