Map: school disruptions and closures in California so far this school year
What is included in this dataset?
This map shows school closures (cancellations, early releases, delays, and disruptions, including from extracurricular activities) caused by extreme heat, extreme cold, flooding, wildfire, severe weather, or hurricanes that are reported on by news agencies or district communication channels. The size of the dots correspond to the number of students whose learning was impacted by each closure or disruption.
The data represent a conservative estimate of the impacts of climate-related school closures on student learning in California during the 2025-26 school year. With closure information pulled from news articles, the numbers likely underestimate the true scope of impact.
Have a question or information on a closure?
This map is being updated throughout the 2025-26 school year. If you have a question, information to share about a school closure near you, or if you know of a closure not reflected on this map, please fill out this form.

What the research says: severe weather impacts learning and school budgets—and no school is immune.
Student absenteeism from weather-related events causes outsized learning loss. For every week of school missed due to extreme weather:
Students in grades 3–5 lose at least two weeks of learning in math and reading
Students in grades 6–8 lose at least four weeks of learning in math and three weeks of learning in reading

This August 2025 research brief from NWEA raises awareness of the scale and variation of educational impacts from the growing number of weather-related challenges facing U.S. schools.
Findings highlight four key takeaways:
1) Many U.S. schools face major budget and infrastructure challenges related to severe weather
2) Teachers need support to meet students’ varied needs following a weather-related disruptions
3) A day of school missed after a severe weather event can translate to more than a day of learning lost
4) No school is totally “low-risk” from weather-related disruptions.
In the 2024-25 school year, California students lost more than 8 million instructional hours.
