San José

Costa Rica

San José is projected to face heightened climate risks, particularly in the form of frequent heatwaves and heavy rainfall events. The increase in heatwaves is expected to raise temperatures, posing threats to public health, agriculture, and energy demand. Concurrently, heavy rainfall events will likely lead to flooding and strain the city’s drainage and infrastructure. These climate hazards may exacerbate urban vulnerabilities, leading to increased social and economic disparities. Additionally, the potential for infrastructure damage during intense rainfall raises concerns for the city's resilience. As these climate challenges worsen, it is essential to monitor and prepare for their impacts, as technology-enabled climate resilience solutions have not yet been documented for this city. Addressing these vulnerabilities is critical for the community's long-term sustainability and safety.
