The tanning season here is short — maximize the summer months when UV levels are adequate. On low-UV days, longer sessions with proper hydration can still produce a gradual tan.

SPF 15-30 is adequate during summer tanning sessions. In winter, UV levels are typically too low to require sunscreen for tanning purposes, though daily SPF is always good skincare practice.
