Health Considerations in California
California's climate varies dramatically by region: coastal areas experience mild temperatures year-round, while the Central Valley and Inland Empire face extreme summer heat, high ozone levels, and seasonal wildfire smoke that significantly worsens respiratory conditions. Wildfire season has expanded and intensified in recent years, making smoke-related respiratory visits — particularly for asthma, bronchitis, and eye irritation — common across northern and central California from summer through fall.
