Here's the link to the North Beach pool schedule. Every city public pool's schedule is on the SF Parks & Recs web site. You can always go to McClaren Lodge in GG Park for help or call any of the individual pools during operating hours for assistance. Good luck. https://drive.google.com/file/d/1-oZ-YINdY_NAI49AXH0yMbGafpt-eAwQ/view?usp=drivesdk
