Activity Guidelines
4 The health impact of haze is dependent on one’s health status, the PSI level, and the length and intensity of outdoor activity. For immediate outdoor activities, please check the 1-hr PM2.5 concentration readings and personal guide. Use the 24-hr PSI forecast and corresponding health advisories for planning next day outdoor activities.
