Air quality around Swan Hill is generally good, typical of a smaller regional centre with limited industry, though dust from surrounding dryland and irrigated farming, particularly during cultivation, harvest or windy dry spells, is a recurring feature. Occasional smoke from agricultural burning or regional bushfires in mallee country can also affect conditions. Low humidity and hot, dry summers are characteristic of this semi-arid stretch of the Murray, allowing dust to build on still, dry days.
