Does turning on the air conditioner help?
I am assuming air conditioning is common down there.
It depends on the part of San Diego. I lived in Mira Mesa. Air conditioning was only really necessary about 1 week each year. I didn't have it in my house at all. Neither did my parents in Chula Vista. Santee and El Cajon are places that you want air conditioning. They fall in the "inland" climate area vs the "coastal" where I lived. It is mostly unnecessary in the "mountain" climate zone and an absolute necessity in the desert area. San Diego weather forecasts include information for coastal, inland, mountain and desert zones.
