Purpose <p>The aim of this review is to synthesize recent literature and epidemiologic evidence on the impact of specific extreme weather events on asthma- and allergy-related outcomes.</p> Recent findings <p>Extreme weather events and natural disasters are increasing in prevalence and severity at least in part due to climate change, and these events have measurable adverse effects on those with asthma and allergic disease.</p> Summary <p>The findings discussed in this article underscore the significant vulnerability of individuals with asthma and allergic disease to extreme weather events and associated environmental stressors. As climate change progresses, pollen seasons are expected to lengthen with higher aeroallergen concentrations, fungal spore burdens are likely to increase, and overall air quality is projected to worsen. Recognizing the expanding impact of these changes on asthma and allergic disease is essential. Continued research is needed to identify reliable biomarkers and clinical indicators for individual risk stratification, as well as to advance meteorological forecasting tools and exposure-mitigation strategies.</p>
