Water from your tap can smell different depending on the time of year — and that’s usually normal. Seasonal changes in temperature, rainfall, and city demand affect how water moves through pipes and storage tanks.
Warmer months may intensify chlorine smell, as higher temperatures slightly increase evaporation and perception of taste and odor. Cooler months can make water feel flatter or less aromatic. Heavy rainfall or snowmelt can also temporarily affect water sources, subtly changing taste or odor at the tap.
These seasonal fluctuations are typically short-lived. Running water for a minute or two usually restores normal smell, and they rarely indicate a health concern.
