During summer season, Southern CA is hot but less muggy or pleasantly comfortable, esp. during night, & at coastal areas, you wouldn't need any air-conditioners, cause it is so pleasantly cool, esp. after 4-5 pm it'll get 60-65F. ( In winter, it'll get to 35-40F). But in the northeastern areas such as NYC & Northern NJ where I had worked & resided, the air-conditioner is an absolute necessity & not a luxury item on account of that incredible sultry, muggy weather.
