The June heat was relentless across most of the United States and Canada. Only parts of the Southern Plains and the Southeast in the United States, and Northern Canada east and west of Hudson Bay, were a little cooler than normal. The most brutal conditions were experienced in the Western United States and Southwestern Canada. The town of Lytton, British Columbia, broke the Canadian temperature record three days in a row, ending with a reading of 121 degrees on June 29. The next day, most of the town was destroyed by a wildfire, in which two residents were killed.
