Oslo residents are seeking refuge in parks and swimming areas as extreme heat tests the city's infrastructure.
Did You Know? Asphalt in Oslo can reach temperatures of 60 to 70 degrees Celsius when the outdoor air temperature is 35 degrees, according to researcher Maria Korkou.
Infrastructure Gaps and Resident Experiences
Citizens report a lack of cooling facilities in public spaces and transit. Mina Wilson, a 26-year-old resident, described city buses as a “nightmare” and noted a lack of air conditioning and drinking fountains in parks.
Water quality is also a concern. Wilson stated that some nearby swimming areas contain “poop water,” which she characterized as “unserious.” Others, like Louise Larsen Dahl, noted a lack of parasols and shade at beaches, relying instead on home heat pumps with cooling functions to manage apartment temperatures.
The Impact of Urban Heat Islands
Maria Korkou defines urban heat islands as areas where city temperatures are noticeably higher than surrounding rural zones. She identifies Alna, Skøyen, Grorud, Oslo city center, and Frogner as high-risk areas due to dense concrete, asphalt, and old buildings.
Korkou reports that studies indicate these specific areas could be four to five degrees warmer, with night temperatures rising by two degrees. Areas near railway tracks are also identified as particularly prone to extreme heat.
City Strategy for a Greener Oslo
Marit Vea, the City Councilor for Environment and Transport, stated that the city now knows exactly which buildings and areas are most exposed to heatwaves. This data comes from a NINA report commissioned by the City of Oslo’s Climate Agency.
Vea is prioritizing “park streets” and increased vegetation to make the city physically greener. The goal is to implement targeted measures, such as cooling solutions and more trees in schoolyards and local neighborhoods.
Vulnerable Populations and Urgent Timeline
Korkou warns that the elderly, children under five, and individuals with existing health problems are most at risk. She also notes that people with low incomes often live in older buildings in poorer condition, increasing their exposure.
NINA is currently prioritizing 20 kindergartens and schools, along with 10 health institutions, for increased tree planting. Korkou emphasizes that this is urgent, as trees along roads can lower temperatures by ten degrees or more when it is 35 degrees outside.
Future heatwaves may become more intense across Eastern, Southern, and Western Norway, according to Korkou. Cities with dense structures and high populations are likely to remain more exposed than smaller settlements.
Frequently Asked Questions
Which areas of Oslo are most affected by urban heat islands?
According to Maria Korkou, the most exposed areas include the city center, Frogner, Alna, Skøyen, and Grorud, as well as areas near railway tracks.
Why are Norwegian buildings poorly suited for heatwaves?
Korkou explains that Norwegian buildings are designed to keep out winter cold; they are well-insulated with double windows that can act like a greenhouse during extreme heat.
What is the city doing to mitigate the heat?
City Councilor Marit Vea states the city is focusing on making Oslo “physically greener” through park streets and adding trees and shade to schoolyards and neighborhoods.
Do you think your local neighborhood is prepared for more frequent heatwaves?
