Hi, have you ever been there in the Summer? We lived there for quite a while, and it is different.
I haven't been there at all. I had a friend in San Diego who made a regular trip to Bullhead City to visit his mother.
The average low in Bullhead City is 43 in Dec/Jan and 79 in Jul/Aug. The average high is 65 in Dec/Jan and tops at 112 in Jul. Jun to Sep average high is always above 103. The temperature gets above 90 degrees for 181 days each year. Annual precipitation is 6.31 inches. Pretty darn hot and dry. Looks like a candidate for year round air conditioning.
Personally, I dislike humidity. I have yet to experience a humid day in Pocatello. Snow is fine. It means I don't have to mow the lawn. That would have been welcome today as I pushed my mower over 3/4 acre of grass. The ambient temperature was 54 degrees and the air was dry. I didn't even break a sweat. Quite an improvement over a humid August day in San Diego.
