However, as of November 13, 2026, there is no reliable confirmation that the California Department of Corrections and Rehabilitation (CDCR) has ordered a new statewide lockdown today. Recent reporting instead documents lockdowns affecting parts of an individual prison.
According to a November 12 report by KPBS, records obtained through a public records request confirmed that indoor temperatures at several areas of Donovan prison exceeded 90 degrees during September’s heat wave. The facility experienced lockdowns between September 10 and September 17 after what CDCR described as security concerns. The department also said an incarcerated person had attacked and injured a correctional officer on September 9.
The lockdowns reportedly restricted movement and access to certain cooling resources, including large fans and ice water. Incarcerated people interviewed by KPBS questioned whether adequate heat-safety measures were maintained while restrictions were in place.
The situation has also attracted attention from California lawmakers and prison advocates. Assemblymember Nick Schultz, chair of the Assembly Public Safety Committee, has expressed concern about the conditions and said he plans to push for oversight hearings when lawmakers return in January.
CDCR uses temporary modified programs when security threats, violence, contraband discoveries or investigations require restrictions. Such measures can affect visitation, communications, recreation and daily movement. They are not automatically statewide orders and may apply only to specific facilities or housing areas.
For families and friends of incarcerated people, the distinction is important. Anyone planning a visit should check the official CDCR facility visiting-status information before travelling.
As of the latest available reports, the claim of a new statewide lockdown remains unconfirmed. Further official information would be needed to establish whether additional California prisons have been placed under restrictions.
