Summary
Escondido hit 112 degrees and Vista 105 on Wednesday, breaking Sept. 9 records by 8 and 7 degrees as the heat wave tied to former Hurricane Marie reached its peak.
National Weather Service readings showed the broader spread of the surge: 108 in El Cajon and Gillespie Field, 107 in Fallbrook, 105 in Rancho Bernardo and San Marcos, and 93 at San Diego International Airport.
Tropical moisture made the heat more oppressive, with forecaster Paul Steward saying the air felt hot and steamy rather than just dry.
Thursday should start a cooldown, and the weather service expects temperatures to return to seasonal levels by the weekend.
