Triple-digit heat is pounding much of California in mid-July, and state leaders are trying to make sure kids are not the ones paying the price on the playground or during P.E. Two new state laws are reshaping how schools handle extreme weather: one requires written protocols for outdoor activity, and the other nudges the state to teach students how to recognize and respond to heat illness.
On July 13, 2026, Gov. Gavin Newsom signed Assembly Bill 1653, directing the Instructional Quality Commission to consider adding heat-illness prevention and response content to the Health Framework for California public schools. The law spells out the kind of material the commission should weigh, including basic prevention steps, how to spot symptoms and simple actions such as stopping activity, moving to shade and hydrating, according to Legislative Information.
The second measure, Senate Bill 1248, requires school districts, county offices of education and charter schools to develop and implement weather protocols for extreme conditions, with clear thresholds for changing or canceling outdoor activities and indoor alternatives when it is simply too hot to be outside. The law sets an implementation deadline of July 1, 2026. Momentum for the bill picked up after the August 2023 collapse and death of 12-year-old Yahshua Robinson during P.E., a case that reignited scrutiny of athletic and recess rules in triple-digit heat. Reporting on that tragedy and its fallout is available from the Los Angeles Times.
Funding shortfall stalls cooling upgrades
Advocates say the new rules are helpful but warn they do not fix a deeper problem: many campuses are still running on aging cooling systems, if they have air conditioning at all. The CalSHAPE program, created to help schools upgrade ventilation and plumbing, paused new applications in mid-2024 as administrators wrestled with tight timelines and remaining funding.
An audit from the California State Auditor concluded the California Energy Commission is unlikely to spend all CalSHAPE dollars and that roughly $200 million could be returned to utilities if the Legislature does not act. At the same time, program pages from the California Energy Commission show the plumbing grant track is closed and ventilation guidance is being updated, leaving districts in a bit of a holding pattern just as the heat is ramping up.
What schools must do now
Under SB 1248, districts are required to adopt protocols that spell out how staff will respond when the mercury climbs. Those plans must include standardized temperature thresholds or index ratings that trigger changes to outdoor physical activity, procedures for monitoring weather forecasts, designated indoor alternatives and staff training on how to recognize heat stress.
The law tasks the State Department of Education with compiling and posting guidelines and offering technical assistance, although the bill text makes clear that rolling all of this out depends on state funding. The full measure is available through Legislative Information.
Public health data highlight why lawmakers are sounding the alarm. Tracking California recorded 618 emergency-room visits for heat illness among 5 to 17-year-olds in 2024, roughly a 30 percent jump from the prior year, according to Tracking California. Groups monitoring school disruptions say tens of thousands of instructional hours were lost last school year because classrooms or playgrounds were simply too hot to use.
"Children in California are already being harmed by extreme heat," Sarah Matsumoto told reporters, arguing that safety lessons and weather protocols are necessary but not sufficient. Advocates stress that long-term protection will also require funded HVAC upgrades, shade structures and other projects that make campuses physically cooler, not just more rule-compliant.
Legal implications
The two new laws create enforceable duties for local education agencies and weave those obligations into the state budget process. Districts, county offices and charter schools will have to layer new procedures on top of existing responsibilities, all while working within finite staffing and facilities budgets.
Because the legislation adds responsibilities at the local level, education leaders are watching to see whether the state or the Commission on State Mandates finds that any of the associated costs are reimbursable under state law, a decision that could reshape how districts budget for heat safety in the years ahead. For a sense of the remaining CalSHAPE funds and the fiscal choices confronting lawmakers, see the analysis from the California State Auditor.
Lawmakers and advocates largely agree that the new rules are a start, not a finish line. Protecting students over the long haul will take money as well as mandates, with the next state budget cycle serving as a real-world test of whether California can match its heat safety promises with the cash to cool classrooms and shade playgrounds.
