Background: Given the rapid global increase in asthma cases, understanding the impact of climate change on respiratory health is necessary for evidence-based policymaking, particularly in low- and middle-income countries (LMICs). Objectives: To estimate the short-term associations between temperature (mean and diurnal range), particulate matter (PM 2.5 and PM 10 ), nitrogen dioxide (NO 2 ), ozone (O 3 ), and childhood asthma exacerbations in Cape Town, South Africa. Methods: We analysed daily hospital records ( n = 7753; 2009, 2014, 2019) alongside citywide air quality and meteorological data using negative binomial mixed-effects models and distributed lag non-linear models to capture delayed effects. Results: NO 2 and PM 10 were consistently associated with a higher exacerbation risk, with additional delayed effects observed for PM 2.5 , PM 10 , and NO 2 . Mean temperature and diurnal temperature range were also linked to an increased risk at short (lag 0-1) and medium (lag 4-5) delays. Conclusions: Temperature variability and traffic-related air pollution contribute to childhood asthma exacerbations in urban LMIC settings. The findings support child-centred early warning systems and stricter air quality controls aligned with WHO guidance
