Ranked by deaths, injuries, damage and size together.
- Excessive Heat in Virginia, June 8, 2008A strong ridge of high pressure set up across the eastern United States for several days in early to mid June. High temperatures reached into the mid to upper 90s across northern Virginia on June 8.
- Excessive Heat in Virginia, June 23 to 25, 2025A prolonged heatwave impacted portions of eastern and central Virginia over the course of three days from June 23 to 25. Each day, heat indices reached 105-115 degrees with high temperatures in the upper 90s to around 100 degrees and dew points in the upper 70s.
- Excessive Heat in Virginia, July 21 to 23, 2011An extended period of excessive heat and humidity occurred across most of central and eastern Virginia from July 21st to July 23rd. High temperatures ranged from 96 to 103 degrees during the afternoons, with heat index values ranging from 110 to 119.
- Excessive Heat and Heat in Virginia, July 3, 2018An upper-level high along with surface high over the western Atlantic led to hot and humid conditions.
- Excessive Heat and Heat in Virginia, July 19, 2019Temperatures from the mid 90s to near 100 degrees combined with dew points near 70 degrees to create dangerously high heat index values.
- Excessive Heat and Heat in Virginia, July 21, 2019Temperatures from the mid 90s to around 100 degrees combined with dew points in the 70s to create dangerously high heat index values.
- Excessive Heat and Heat in Virginia, July 20, 2019Temperatures from the mid 90s to the lower 100s combined with dew points near 70 degrees to create dangerously high heat index values.
- Excessive Heat in Virginia, January 2 to 4, 2000High pressure off the Southeast U.S. coast turned winds southerly over the Mid-Atlantic region on the 2nd, starting a conveyer belt of warm air that would remain over the region through the 4th. With ample sunshine, high temperatures reached the mid 60s to low 70s.
- Excessive Heat and Heat in Virginia, August 13, 2016A southerly flow around high pressure ushered in unseasonably hot and humid conditions.
- Excessive Heat in Virginia, July 22, 2011Strong upper-level high pressure built over the region during the 22nd. Surface high pressure over the Atlantic Ocean caused moist air to move into the region from the south.
- Excessive Heat and Heat in Virginia, July 21, 2011Upper-level high pressure provided enough subsidence to cause hot conditions on the 21st. Surface high pressure over the Atlantic caused moist air to move into the region from the south.
- Excessive Heat in Virginia, July 27, 2025A heatwave impacted southeast Virginia on July 27. Heat indices reached 110-115 degrees with high temperatures in the mid to upper 90s and dew points in the mid 70s to around 80 degrees.
- Excessive Heat and Heat in Virginia, July 25, 2016A southwesterly flow around high pressure over the Atlantic pumped in plenty of moisture while hot conditions persisted due to an upper-level ridge of high pressure. The heat and humidity caused dangerous heat indices.
- Excessive Heat and Heat in Virginia, June 29, 2012Plenty of moisture from the Gulf of Mexico caused high humidity during the 29th. Upper-level high pressure along with sunshine caused extremely hot conditions. The combination of the heat and humidity caused heat indices to be near or above 105 degrees.
- Excessive Heat and Heat in Virginia, July 19, 2013High pressure was located over much of the eastern United States for a consecutive day and light southerly flow persisted all week which led to above normal temperatures and dew points in the mid 70s.
- Excessive Heat in Virginia, July 28, 2023The combination of a strong upper-level high pressure over the central United States and moist southwest winds resulted in hot and humid conditions across the Mid-Atlantic that produced excessive heat conditions.
- Excessive Heat and Heat in Virginia, July 7 to 8, 2012Upper-level high pressure built overhead while surface high pressure moved off the coast. A southerly flow combined with sunshine and subsidence for hot and humid conditions.
- Excessive Heat in Virginia, July 15, 2024Hot and humid conditions overspread much of the region on July 15 and July 16, resulting in the hottest temperatures of the Summer in 2024. Heat index values reached and exceeded 100 to 110, with daily record high temperatures tied and set.
- Excessive Heat in Virginia, July 16, 2024Hot and humid conditions overspread much of the region on July 15 and July 16, resulting in the hottest temperatures of the Summer in 2024. Heat index values reached and exceeded 100 to 110, with daily record high temperatures tied and set.
- Excessive Heat in Virginia, June 23, 2025A large area of high pressure across the region brought extreme heat and humidity to the Mid-Atlantic.
- Excessive Heat in Virginia, June 24, 2025A large area of high pressure across the region brought extreme heat and humidity to the Mid-Atlantic.
- Excessive Heat in Virginia, July 10, 2024Hot and humid conditions overspread the area on July 10, producing heat indices above 100 to 110.
- Excessive Heat in Virginia, February 25, 2000Afternoon high temperatures reached well into the 70s, with a few urban valleys around 80 degrees. Preliminary data from the cooperative observers indicated 75 degrees from Clintwood and Breaks Interstate Park, while Grundy had 81 degrees.
- Excessive Heat in Virginia, February 26, 2000A second day in February with afternoon temperatures well into the 70s. Clintwood and the Breaks Interstate Park felt 76 degrees.
- Excessive Heat in Virginia, March 8, 2000Thermometers peaked in the upper 70s to mid 80s during the afternoon. A few of the preliminary maximum readings included 85 degrees from Grundy and 81degrees from both Clintwood and Breaks Interstate Park.
