Why this summer season will be the longest until 2037
- 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.
- 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.
- Human-caused climate change is contributing to hotter and longer summers, and despite an El Niño pattern, preparation for major hurricanes is advised.
