Bracing for Impact: Heatwaves and Wildfire Smoke Set to Challenge BC’s Lower Mainland in Summer 2025

By Jenny Holly Hansen | WBN News | May 8, 2025

As we move into the summer of 2025, the Lower Mainland of British Columbia is bracing for a season marked by extreme heat and heightened wildfire activity. Building upon the challenges faced during the 2021 heat dome and the record-breaking 2023 wildfire season, current forecasts suggest that this year could bring even more severe conditions.

Heat and Drought: A Dangerous Duo

Environment Canada predicts that Metro Vancouver will experience above-average temperatures and drier conditions throughout the spring and into early summer. This trend is expected to continue into June, with warmer-than-usual temperatures and reduced precipitation levels . These conditions are conducive to the development of heatwaves, increasing the risk of heat-related illnesses and placing additional strain on infrastructure and public health systems.

Wildfire Season: An Escalating Threat

The 2025 wildfire season in British Columbia is already showing signs of increased activity. As of early May, there have been 159 wildfires reported in the province, burning over 1,550 hectares of land. The majority of these fires have been attributed to human activity, underscoring the need for public awareness and preventive measures.

Several factors are contributing to the heightened wildfire risk this year:

• Climate Patterns: The El Niño event of 2024-2025 is expected to bring above-average temperatures and lower precipitation levels, creating a high-risk fire season across BC.
• Drought Conditions: Prolonged droughts in regions like the Okanagan Valley and Cariboo have left forests and grasslands highly flammable.
• Fuel Accumulation: An abundance of dry vegetation provides ample fuel for wildfires, increasing their potential severity and spread.

Smoke and Air Quality: A Growing Concern

With the increase in wildfire activity, air quality is expected to deteriorate, particularly in the Lower Mainland. Smoke from wildfires contains fine particulate matter (PM2.5), which can penetrate deep into the lungs and bloodstream, causing a range of health issues. Real-time smoke forecasts are available through platforms like FireSmoke.ca, providing valuable information for residents to plan and protect their health.

Health Impacts: The Combined Effect of Heat and Smoke

Exposure to extreme heat and wildfire smoke individually poses significant health risks. However, when these two factors coincide, their combined effect can amplify health problems, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Studies have shown that simultaneous exposure to heat and smoke can lead to increased hospitalizations for respiratory and cardiovascular issues.

Preparing for the Season Ahead

Given the anticipated challenges, it's crucial for residents and businesses in the Lower Mainland to take proactive steps:

• Stay Informed: Regularly monitor weather forecasts and air quality indexes.
• Create Emergency Plans: Develop and rehearse evacuation plans, and ensure that emergency kits are stocked and accessible.
• Protect Indoor Air Quality: Invest in high-efficiency air purifiers to reduce indoor pollution levels.
• Stay Cool: Utilize air conditioning or designated cooling centers during extreme heat events.
• Support Vulnerable Individuals: Check on neighbors, family, and friends who may be more susceptible to heat and smoke-related health issues.

As we face the challenges of the 2025 summer season, proactive preparation and awareness are key to safeguarding health and well-being. By staying informed and equipped, we can better navigate the impacts of extreme heat and wildfire smoke in the Lower Mainland.
