This paper presents a preliminary analysis of meteorological variables and their relationship with respiratory morbidity in children under two years old of São Paulo city, taking into account the synoptical systems and their constructive structures of residences. Measurements of indoor air temperature and relative humidity were collected using a thermohygrographic across of 378 residences, between years 2003 to 2006. Outdoor meteorological variables have been obtained from meteorological station. A summary with four case studies is shown relating the thermal behavior in each residence and the onset of respiratory illness in children (wheezing). The results show associations of children respiratory crises and air temperature fall and increase of relative humidity, associated with maritime polar air masses and frontal systems (cold front). Specific residences have higher indoor humidity values than others, due to their constructive types and it is an important factor to bring out wheezing problems. Considering such results, acknowledging periods favorable to occurrences of wheezing in children, as well as the constructive type of residences, it is feasible to predict respiratory morbidity and to establish public policy in order to alert the population, minimizing weather/climate impacts on children's health
