The proposed bill aims to enhance student safety by prohibiting public schools from scheduling, hosting, or requiring outdoor practices, scrimmages, games, or activities for extracurricular activities during periods when an excessive heat warning has been declared by the National Weather Service. The bill defines "extracurricular activity" to include various intraschool and interschool activities that fall outside the regular curriculum, such as athletic events, fine arts programs, and special interest clubs.

Additionally, the bill specifies exceptions to this prohibition, allowing such activities to take place if they occur in water or within a climate-controlled indoor facility. This legislative measure seeks to protect students from the dangers of extreme heat while participating in extracurricular activities.
