With high temperatures in the forecast, the City of Vista invites residents to take advantage of local Cool Zones—safe, air-conditioned public spaces open to all ages.

San Diego County Moutains and Valleys will be experiencing a Heat Advisory through 8 pm Wednesday, June 18, 2025. San Diego County valleys and mountains may reach temperatures up to 100 degrees Farenheit. 

Hydrate with water, find shade, wear sunscreen, and take breaks when outside. If possible, stay in air-conditioned buildings as much as you can. Keep animals in cool places and hydrated with water. Never leave your animals in unattended parked cars.

Official Cool Zones are available at these locations:

• McClellan Senior Center (1400 Vale Terrace Drive): Open weekdays from 8:00 am to 3:30 pm.
  
  
• Vista Library (700 Eucalyptus Avenue):
  • Monday: 10:00 am – 6:00 pm
  • Tuesday & Wednesday: 12 pm – 7 pm
  • Thursday: 10 am-6 pm
  • Friday through Sunday: 10 am-5 pm
  • (Please note: the Library will be closed on June 19)

Whether you need a break from the heat or a place to relax, Vista’s Cool Zones offer a comfortable space to stay safe and refreshed.

Stay Safe in High Heat 

As temperatures rise in Vista and across Southern California, it’s important to take steps to stay safe and cool. High heat can be dangerous, especially for older adults, young children, and those with underlying health conditions. Here are some simple but effective ways to protect yourself and your loved ones during hot weather:

🔹 Stay Hydrated

Drink plenty of water throughout the day, even if you don’t feel thirsty. Avoid alcohol, caffeine, and sugary drinks as they can lead to dehydration.

🔹 Limit Outdoor Activity

Try to stay indoors during the hottest parts of the day—typically between 10 a.m. and 4 p.m. If you need to be outside, take frequent breaks in the shade and pace yourself.

🔹 Dress for the Weather

Wear lightweight, loose-fitting clothing and a wide-brimmed hat. Light-colored fabrics help reflect heat. Don’t forget sunscreen!

🔹 Keep Indoor Spaces Cool

Use fans, close blinds or curtains, and avoid using heat-generating appliances like ovens during the day. If you don’t have air conditioning, spend time in air-conditioned public places like the Vista Library or the McClellan Senior Center—both are designated Cool Zones.

🔹 Know the Signs of Heat Illness

Watch for signs of heat exhaustion: heavy sweating, weakness, dizziness, nausea, and headache. Heat stroke is a medical emergency and includes symptoms such as confusion, fainting, and a high body temperature. Call 9-1-1 if you suspect someone is experiencing heat stroke.

🔹 Check on Vulnerable Neighbors

Take a moment to check in on neighbors, especially seniors or those with mobility issues, to make sure they are staying cool and hydrated.

🔹 Don’t Forget Pet Safety

Never leave pets in a parked car, even for a few minutes. Make sure pets have access to shade and plenty of fresh water. Hot pavement can burn paws—walk pets early in the morning or later in the evening when temperatures are lower.
