The calendar says it’s the first of August. But an unforgiving early wave of heat means that California’s landscape feels as dry as September, igniting a deadly wildfire season up and down the state. Hot and dry as a powder keg, recent weather has accelerated the normal drying of western landscapes, turning vegetation into kindling, say weather experts. Even nights are warm. “Fuels are really really dry. It’s closer to what we should get by late summer or early fall,” said professor Craig Clements, director of the Fire Weather Research Lab at San Jose State University.
