The unofficial summer season of 2026 is projected to be the longest until 2037, lasting 106 days from Memorial Day to Labor Day. This extended duration is due to a calendar quirk, allowing for the earliest possible Memorial Day and the latest possible Labor Day.
Extended Summer Brings Increased Risks
The longer summer brings an increased risk of heat-related illnesses, ticks and severe weather events, including flash floods and derechos. Forecasters anticipate above-average temperatures across most regions, with an elevated wildfire risk for the Northwest and Great Basin.
Climate Change and Weather Patterns
Human-caused climate change is contributing to hotter and longer summers, and despite an El Niño pattern, preparation for major hurricanes is advised. Residents are urged to stay informed and take precautions against the heightened dangers associated with the prolonged season.
