Summertime Temperatures

September 2023

While warm weather is usual for this time of year, no impacts to campus operations are anticipated at this time. As the fall semester commences and continues, weather will start to cool but can still remain warm in early September. This is an important reminder that excessive heat requires additional awareness from everyone in order to avoid heat-related illnesses, which can lead to potentially serious medical conditions.

  • Stay hydrated. Drink plenty of water throughout the day, even if you do not feel immediately thirsty.
  • Limit outdoor activities. Particularly during the hottest parts of the day: between the hours of 11 a.m. and 3 p.m.
  • Find the shade. If outdoors, seek out areas away from the direct sun and walk in shaded areas.
  • Take breaks. Pace yourself throughout the day if outdoor activity or movement outdoors is unavoidable.
  • Wear sunscreen and/or a hat. Apply sunscreen at least every two hours and limit your skin's exposure to the sun.
  • Recognize heat-related illness. Review the Centers for Disease Control and Prevention's warning signs and symptoms and call 911 if you are experiencing severe symptoms.
  • Limit alcohol intake. Alcohol can dehydrate you faster and causes body temperature to rise, making you more vulnerable to heat-related illness.
  • Know your own risk. Some medications can create greater sensitivity to sun and heat, and medical conditions such as heart and respiratory disease and diabetes can increase the risk of heat-related illnesses. Heat-related illness is also more prevalent in older populations.
  • Prepare for heat indoors. Some indoor spaces, especially those lacking proper ventilation, insulation or air conditioning may heat up quickly and retain their heat throughout the day into the evening. Prevent heat by opening doors and windows during cooler hours (early morning, late evening) and cover windows during the daytime. Move to an air conditioned space if conditions do not improve. Review Occupational Health and Safety (OSHA) guidelines for indoor high heat exposure. Prepare for high indoors heat using Red Cross best practices.
  • Move to a cooling center. Find your nearest Santa Clara County cooling center or, if outside of the County, review the most up to date list of cooling centers by county on the state Office of Emergency Services website.

Maintaining a safe and healthy campus environment during the warmest times of the year remains a top university priority. As the fall semester begins, San José's climate usually includes warm weather continuing for the next few months. Stay cool and take care of yourselves, your classmates, your coworkers, your families and your friends!

Challenges Getting to Campus

The university always plans to have all offices and services operational and available to the fullest extent possible while maintaining a safe working environment. Worsening conditions in seasonal weather, most notably during the winter months, may affect everyone's ability to get to campus. Students who are unable to get to campus for class or work, should contact their faculty or supervisors. Staff and faculty facing challenges in reporting to or performing work because of weather-related conditions in your area, should communicate directly with your supervisor or appropriate administrator.  

If your supervisor is not available, please call:
