The Regional District of Okanagan-Similkameen (RDOS) is encouraging residents to take precautions as hot weather is expected across the region this week (beginning Tuesday, July 21, 2026).

Environment Canada has issued a Heat Warning for the South Okanagan, with daytime temperatures forecast between 34°C and 37°C and overnight temperatures remaining between 16°C and 20°C.

Cooling locations available throughout the South Okanagan
As part of the RDOS Extreme Heat Response Plan, residents are encouraged to visit air-conditioned public facilities, including local libraries and community centres, to help stay cool during periods of extreme heat.

Confirmed Okanagan Regional Library cooling locations - July 21, 2026, to July 23, 2026

Residents and visitors are encouraged to confirm facility hours before travelling, as operating hours may vary. More cooling locations and hours may be confirmed.

The RDOS follows British Columbia's Heat Alert and Response System (HARS) and continues to monitor weather conditions closely. Community partners are prepared to implement measures outlined in the RDOS Extreme Heat Response Plan should additional response activities become necessary.

Warmer overnight temperatures can limit the body's ability to recover from daytime heat and increase the risk of heat-related illness. The highest temperatures are expected in Oliver and Osoyoos, where temperatures could reach 37°C on Tuesday. A gradual cooling trend is forecast to begin on Thursday.

Who is most at risk?
Extreme heat can affect anyone, but the greatest risks are faced by:

• Older adults
• Infants and young children
• People with chronic medical conditions
• Individuals who work or exercise outdoors
• People living alone or without access to air conditioning

How to stay safe during hot weather
Residents and visitors are encouraged to:

• Drink water regularly, even before feeling thirsty.
• Limit strenuous outdoor activities during the hottest part of the day.
• Spend time in air-conditioned buildings whenever possible.
• Keep indoor spaces cool by closing blinds and curtains.
• Wear lightweight, loose-fitting clothing.
• Never leave children, pets, or vulnerable individuals in parked vehicles.
• Check on family members, neighbours, and friends who may be more vulnerable to extreme heat.

Seek immediate medical attention if someone experiences:

• Confusion or loss of consciousness
• Severe dizziness
• High body temperature
• Rapid heartbeat
