A heat advisory has been extended for Tuesday in San Diego.
Monsoon moisture from the south is combining with the Santa Ana winds from the east, NBC 7 Meteorologist Jodi Kodesh said.
"We're going to be very hot and humid all day," Kodesh said. "It's going to feel very steamy out there today."
Coastal communities can expect highs in the mid-90s but the humidity will make those temperatures feel higher for residents, she added.
It's also going to be uncomfortable in the inland neighborhoods and foothills.
