Right now in the Central valley of California, it's 90 F (32 Celsius) and it should get up to 97 to 104 (36 to 40 C) over the next 4 days. But that's
par for the course this time of year around here. You get little stretches of 100 degree weather then it calms down again (90's). It's a dry heat though so the 90's are more bearable than if it were humid.
Luckily a nice shady spot outside is comfortable but yes I use my air conditioning quite a bit because of my dog and cats and I don't get good airflow through the apartment.
Just to show you how varied California is:
