Observed on the Contra Costa County website: the county published a heat-safety page with tips and places to cool; the page is the source for the items below.

County guidance: drink cool water and electrolyte drinks; do not wait until you are thirsty; stay in air conditioning when possible and take cool showers or use a frozen wet cloth to cool the head and neck; check on less mobile or older neighbors who lack or avoid air conditioning; wear lightweight, light-colored, loose clothing and avoid the hottest part of the day; do not exercise outside during peak heat; never leave a person or pet in a parked car; the county states that on an 80-degree day the inside of a car can reach 100 degrees in fewer than 10 minutes.

County guidance continued: keep pets hydrated and shaded; use sunscreen SPF 30 or higher; watch local forecasts and extreme heat alerts; and use cooling spaces such as libraries, shopping centers or cooling centers when available.

Transportation and contact details provided on the page: call 211 or Mobility Matters at (925) 284-2207 for transportation assistance; the page lists public transit agency contacts and websites, including Tri Delta Transit (925-754-4040), County Connection (925-676-7500), WestCAT (510-724-7993) and AC Transit (510-891-4777).

Additional resources linked by the county: Contra Costa Health information on heat and health; wildfire preparedness guidance; National Weather Service Bay Area information; registration for the Contra Costa Community Warning System; a PG&E outage center map; and several PDFs including "Prepare For A Power Outage" and "Summer Heat Tips and Places to Cool Off."

Practical consequence: residents should use the county's listed cooling spaces or other air-conditioned locations, arrange transport through 211 or Mobility Matters if needed, register for emergency alerts and review power-outage preparedness materials before heat events.

Limits and uncertainties: the county page notes PDFs and external links for more detail; the main page itself does not list specific cooling-center addresses or hours. That gap means residents must follow the provided links or call the listed contacts to find exact locations and schedules.

Analysis and inference: the guidance emphasizes electricity-dependent cooling and links to outage-preparedness materials; preparing for power loss is therefore a practical priority but the county page does not quantify cooling-center capacity or availability during widespread outages.
