Southern California — A Cal/OSHA heat illness warning is urging employers to strengthen workplace protections as triple-digit temperatures spread across the region from July 22 through July 27. For employees working outdoors or in hot indoor spaces, the forecast may bring physical strain, concern about unsafe conditions, and a greater need for clear emergency procedures.
Triple-Digit Heat Forecast Across Southern California Counties
Cal/OSHA issued the advisory on July 21, following the National Weather Service’s issuance of heat advisories and extreme heat watches for Los Angeles, Ventura, Orange, Riverside, San Bernardino, and San Diego counties.
The heat was expected to begin on Wednesday, July 22, peak on Thursday, and remain above normal through Monday, July 27. Inland Riverside and San Bernardino counties could reach 100 to 107 degrees, while parts of the Antelope Valley could climb to 108 degrees.
Forecasts for Twentynine Palms, Yucca Valley, and nearby high-desert communities reached 114 degrees. The agency reminded employers to provide drinking water, shade or cool-down areas, rest periods, employee training, and effective emergency response procedures.
What California’s Heat Standards Require From Employers
The Cal/OSHA heat illness warning covers many California workplaces. Outdoor employers must offer shade above 80°F and provide cool-down breaks on request. Most indoor workplaces follow the heat standard at 82°F. Some outdoor industries must adhere to extra procedures at 95°F.
Employees should check whether employers:
- Supply fresh, suitably cool drinking water.
- Provide accessible shade or a cool-down area.
- Allow preventive rest without pressure to keep working.
- Maintain a written prevention plan and provide training.
- Respond promptly when warning signs appear.
Workers may submit a confidential safety complaint to Cal/OSHA. California law also prohibits retaliation for reporting safety concerns or for filing a complaint.
Take Action When Workplace Heat Protections Are Missing
Employees shouldn’t have to choose between finishing a shift and raising safety concerns. When an employer fails to provide heat protection, ignores hazards, or punishes workers for speaking up, legal guidance can clarify options.
