<p>This study leveraged location-based data to examine cooling center usage as an adaptation strategy for hurricane-blackout-heat compound hazards during Hurricane Beryl (2024) in Harris County, Texas. We found that census block groups (CBGs) closer to cooling centers and those with lower income were more likely to seek heat refuge at cooling centers after Beryl. Harris County strategically placed cooling centers closer to lower-income CBGs. Using formal and informal cooling centers (operated by the government and volunteer organizations, respectively) had no statistically significant difference. We also investigated seeking heat refuge in hotels as an expensive alternative adaptation strategy. CBGs with higher proportions of older age and limited English proficiency had stronger tendencies to use hotels. These findings highlight the importance of equitable access to cooling centers and the need for targeted outreach and support to ensure that populations with access and functional needs can effectively utilize these critical adaptation resources.</p>
