Extreme weather

UBC’s Vancouver campus experiences a unique micro-climate that can differ significantly from surrounding areas. Weather conditions can change quickly, and it’s important to be prepared for all types of extreme weather. 

Each faculty/department is responsible for setting their own policies and expectations with faculty/staff attendance and operations during extreme weather. In extreme weather situations, campus-wide updates about closures, class cancellations, and exam rescheduling will be posted on ubc.ca

We recommend downloading the UBC Safe Vancouver App and enabling push notifications to receive immediate alerts and updates during extreme weather events. 

Extreme heat

Rising temperatures can cause serious health and safety implications. Your body has to work harder to maintain its normal optimal temperature on hot, humid days. Heat exhaustion and heat stroke are serious but preventable. In addition, hot temperatures can worsen pre-existing health conditions.

Heat warnings

A heat warning may be issued by Environment Canada when daytime and overnight temperatures are higher than usual, but they are not getting hotter every day. Prioritize staying cool and watch for signs of heat illness.

Extreme heat alert

An extreme heat alert is issued when daytime and overnight temperatures are higher than usual, and they are getting hotter every day. If an extreme heat emergency is declared, it is important that you have a personal emergency plan. Pay attention to the information from your local authority and trusted sources.

Who is at higher risk?

  • Extreme heat affects everyone, but some people are at a higher risk of health impacts, including:
    • Older adults, aged 50 years or older 
    • Infants and young children 
    • People who are pregnant 
    • People with pre-existing medical and mental health conditions 
    • Outdoor workers 
    • People with reduced mobility 
    • People who live alone or are socially isolated 
    • People who live in high density housing with a lack of indoor cooling 
    • Some medications also increase risk of heat illness 

Check on vulnerable neighbours and older adults multiple times a day, especially in the evening.

How to prepare before an extreme heat event

  • Familiarize yourself with the signs of heat-related illness, available in multiple languages
  • Review your plan: Make sure you have the supplies and support you need to stay safe and cool during the hottest parts of the day, typically 11am to 4pm.  
  • Identify your home’s cool zones. 
  • Determine if you can stay at home. If indoor temperatures reach and stay above 31 degrees, plan to stay with friends or family who have air conditioning or a cooler space. Alternatively, identify places in your community you can visit to stay cool such as: 
    • Libraries
    • Community centres
    • Shopping malls
    • Parks and other shaded green spaces
  • Know the location of cooling centres in your community. Cooling centres are air conditioned and open to the public; you don’t need to register, pay or show identification
  • If you work or spend long periods of time outdoors, be aware of the risks of extreme heat combined with humidity, wildfire smoke, and sun exposure.
  • Ensure your pets have access to shade and water. Learn more on the SPCA website.

Prepare your home

A few modifications can make a big difference during periods of extreme heat. Options include: 

  • Close and cover your windows between 10am and 8pm to prevent hot outdoor air from coming inside. Uncovered windows can increase your home’s temperature. Stay alert of your surroundings and sign up for local updates.  
  • Open windows at night to allow cool air in and use fans to move cooler air through the house. 
    • Note: Do not rely on fans as your primary cooling method during an extreme heat event. Fans cannot effectively reduce body temperatures or prevent heat-related illness in people at higher risk 
  • Purchase or install cooling solutions 
    • Look out for rebates and government supports. 
    • See the UNA website for passive cooling solutions and heat pump installation [dependent on UNA site available]  
  • Monitor indoor temperature. Keep easy-to-read thermometers available to accurately measure indoor temperatures (31°C or higher is dangerous for heat-vulnerable people). 

Check on vulnerable neighbours and older adults multiple times a day, especially in the evening. Be sure you are ready!

During an extreme heat warning or extreme heat emergency

If Environment Canada issues a heat warning or alert, take additional steps to stay safe. Monitor local authority websites and trusted sources for guidance, support, and cooling centre location. Drink water, stay cool and rest.

Tips for dealing with heat

  • If you have air conditioning turn it on, if you do not move to your pre-identified alternate location or cooler spaces. 
  • Drink plenty of water 
  • Wear lightweight, loose clothing that breathes well 
  • Take cool baths or showers 
  • If you are taking medication or have a health condition, ask your doctor or pharmacist if it increases your health risk in the heat and follow their recommendation 
  • Lower your outdoor activity level 
  • Avoid direct sun and seek shade when outdoors

If a heat event and poor air quality event occur at the same time, prioritize staying cool.  

Drought

Dry and below normal rain and snow levels are impacting our water levels, resulting in parts of the province experiencing severe drought.  

Drought may have impacts on our drinking water, food, built environments and ecosystems. Responding to drought is a shared responsibility. Reduce water usage where possible and engage in water conservations efforts.

Winter weather and storms

Winter weather, such as extreme cold, snow, hail, high winds and heavy rain, can develop suddenly and pose serious risks to your health and safety. These conditions can lead to cold-related illnesses such as hypothermia and frostbite, as well as injuries from slips, falls, or dangerous driving conditions. Be prepared for power outages. 

In the event of a snowstorm

UBC Facilities leads snow and ice management across campus. Crews monitor detailed weather forecasts and begin clearing high-priority areas—like the bus loop, hospital access points, and major pedestrian routes—before the first people arrive on campus. For more, visit UBC Facilities

  • Check ubc.ca for the latest updates on class cancellations or campus service disruptions. 
  • Refer to the Snow Policy for information on university-wide decisions about closures and curtailments. 
  • Use the UBC Safe Vancouver app for real-time weather alerts and notifications. 
  • Check-in on peers and neighbours who may not receive alerts or required additional supports. 

Tips on staying upright in icy conditions 

  • Adjust your gait: Shorten your stride length to keep your centre of gravity supported. Also, walk with your knees slightly bent, as locking your knees reduces your ability to adjust to a slip. When turning, avoid sharp turns. 
  • Slow down: Take slow, deliberate steps and be on the lookout for icy spots. Place your whole foot down at once, shifting your weight slowly to this foot before stepping with the other foot. 
  • Balance your load: Consider donning a backpack. Backpacks keep your load closer to your centre of gravity. Carrying heavy items in your hands hinders your arms’ ability to provide balance when you do slip. You need your arms free to help you recover your balance if you start to slide. Do not walk with your hands in your pockets for this very same reason. 
  • Wear appropriate footwear: Footwear with a thick rubber or non-slip sole is recommended. Avoid wearing heels and footwear with minimal tread. 
  • Entering/exiting your vehicle: Take care when stepping into/out of your car as you are usually off balance and only on one foot. This increases your chance of slipping. Consider carrying a bag of sand in your vehicle that you can sprinkle on the ground before exiting the vehicle. 
  • Snow-covered curbs: Exercise caution around snow-covered curbs on paths and roadways. 
  • Entering/exiting buildings: Entrance ways may be slippery, exercise caution and report any missing floor mats to UBC Facilities
  • Snow removal equipment: Our winter equipment is fully operational during early morning & daytime hours whenever a snowfall occurs. We are requesting staff and students be aware of moving equipment and be cognizant of the potential risk for pedestrians walking in front of and/or behind operating equipment.Shape 

Windstorm 

Strong winds can strike at any time and may result in falling branches, power outages, and transportation delays.  

To stay safe during a windstorm: 

  • Stay safe, warm, dry and calm. 
  • Stay indoors. If you must go out, dress warmly and watch for flying debris. 
  • Avoid driving unless absolutely necessary. 
  • Develop an emergency plan in advance. 
  • Be prepared for power outages with an emergency kit that includes flashlights, food, water, and battery-powered chargers.
