A significant heat wave swept across the Eastern Seaboard during the week of May 11, 2026, shattering dozens of temperature records but falling just short of the 100-degree Fahrenheit threshold required for a yes resolution. Philadelphia reached 98 degrees on Tuesday, May 13, setting a May record, while Boston hit 96 degrees the same day and Manchester, New Hampshire, recorded 97 degrees — its earliest 95-degree reading in recorded history.
The heat was driven by a persistent high-pressure ridge that channeled warm, dry air from the Plains into the Northeast and Mid-Atlantic. Forecasters had flagged the possibility of triple-digit temperatures in some interior areas, but sustained readings at or above 100 degrees Fahrenheit did not materialize in East Coast cities. By Wednesday, May 14, a frontal boundary began pushing through the region, ending the event.
More than 70 million people across the East were affected during the peak days of the heat wave, and conditions were described as record-breaking for mid-May. The event occurred against the backdrop of the country's warmest 12-month stretch on record across the contiguous United States. The majority of predictors who expected the heat wave to stay below 100 degrees were correct.
