What California's SB 1248 Actually Requires
SB 1248, codified as California Education Code §33355 and known as Yahushua's Law after Yahushua Robinson, a 12-year-old who died of heat illness during a PE class in 2023, requires every local educational agency — school districts, county offices of education, and charter schools — to develop, adopt, and implement a written extreme-weather protocol by July 1, 2026.
The protocol must incorporate the standardized thresholds the California Department of Education was required to publish by January 1, 2026 — guidance that is now live. This is not a recommendation, and it is not limited to athletics. It is a districtwide legal requirement covering outdoor activities across all grade levels.
The July 1, 2026 deadline is the part most plans miss
Districts had the 2025–26 school year to budget, evaluate vendors, and prepare. That window is nearly closed. With the CDE guidance published and the deadline weeks away, the job is no longer planning on paper — it's standing up monitoring, alerting, and recordkeeping that actually work before students are back on the field.
A compliant protocol has to address each of the following:
Temperature, heat index, WBGT, or other index ratings that trigger action — incorporating the CDE's standardized guidelines.
Clear rules for when outdoor activity is modified, relocated, postponed, or canceled — and the indoor or sheltered alternatives to use.
A way to know conditions at each school site — not a regional forecast or a borrowed handheld checked once an hour.
Named responsibilities, escalation steps, and a plan to notify staff, students, and families when conditions change.
Documentation of every decision for audit and liability, plus a yearly review and update of the protocol.
Procedures simple enough that a teacher or recess monitor — not just an athletic trainer — can follow them every day.
SB 1248 is broader than a heat rule
The law and the CDE guidance cover extreme heat, poor air quality, excessive precipitation, and flooding — not heat alone. A compliant protocol has to account for the full hazard set, which is why a single-metric WBGT device only answers one line of the requirement.
Who SB 1248 Covers — and the CIF Carve-Out
SB 1248 applies to PE classes, recess and lunch periods, after-school and summer programs, field trips, and school-sponsored outdoor events — kindergarten through grade 12. Many of those activities happen without an athletic trainer anywhere nearby, which is exactly why the law expects systems a non-expert can follow.
One detail many vendors get wrong
Interscholastic athletics administered by the CIF continue to follow CIF guidelines. SB 1248 governs everything CIF does not — which means a compliant plan has to reach the elementary playground and the recess monitor, not just the varsity field. If your weather-safety approach only works for athletics, it isn't compliant.
Every §33355 Requirement, Covered by One Platform
A single-metric WBGT gadget answers one line of the law. SB 1248 asks for a whole protocol — monitoring, alerting, communication, and records, across every campus. Here's how a complete Weatherstem deployment compares to a standalone WBGT device.
Weatherstem Protect
Protect measures conditions on-site at each campus — WBGT and heat index, with sub-second updates rather than a delayed forecast. It's configured to your district's thresholds, sends text and email alerts as standard, and keeps time-stamped logs for compliance reviews and audits. Installation and ongoing maintenance are included, so the burden doesn't land on your staff.
Weatherstem Blast
Blast is the outdoor warning layer — visual beacons and horns or optional text-to-speech that integrate with Protect to signal a stoppage the moment a threshold is crossed. Alerts are duplicated to administrators with an automated compliance log, so the action and the record happen together.
What a Compliant SB 1248 Protocol Needs
If you're writing or reviewing your district's protocol, these are the pieces §33355 and the CDE guidance expect to see in place.

Weatherstem isn't new to high-stakes weather safety. The same platform California districts can deploy is relied on by state and local emergency management nationwide — including the Florida Division of Emergency Management's statewide network of 240+ stations and New Orleans OHSEP. That's the standard your district's protocol now has to meet, scaled down to your campuses.
- 0.8-second data refresh — faster, more accurate calls than five-minute commercial feeds.
- The whole hazard set — heat and WBGT, lightning, air quality, and severe weather in one platform, with outdoor warning via Blast.
- One dashboard across every campus — consistent thresholds and records districtwide, with 24/7 expert support.
- Hands-off deployment — most stations go live within about six weeks, with installation and maintenance included — in time for July 1.
The July 1, 2026 Deadline
Every California LEA needs an adopted, working protocol on file by July 1, 2026 — and the annual-review requirement means this isn't a one-time task. The districts that move now get a clean deployment before the school year; the ones that wait will be rushing purchases in the worst possible window. Two weeks is still enough time to start the right way.
