Honolulu's Makiki air quality reflects the mid-elevation residential neighbourhood, with vehicle traffic on the surrounding Wilder Avenue corridor contributing modest local sources. The elevated position and the Ko'olau Range backdrop create topographic variation, while Pacific trade winds provide background ventilation and the neighbourhood's residential character and the State Capitol complex's greenspace generally maintain moderate Honolulu metropolitan readings throughout most of the year.
