The global cities that had the driest air in a year, ranked
“How humid will it be today?” A common question for folks around the world to ponder as they plan their day since humidity can affect everything from our hair to our energy levels. The most common way that forecasters measure humidity is by looking at a day’s relative humidity, which considers the amount of moisture present in the air relative to the temperature.
But the most reliable indicator of how dry or humid a day will feel is the dew point, the temperature at which your sweat evaporates and you begin to feel cool. Lower dew point temperatures feel dry, while higher dew point temperatures feel more humid. Using this metric, HouseFresh previously identified the cities across the globe that feel the most humid.
But they couldn’t help but wonder about those cities at the other end of the scale and ask: where in the world do locals live with uncomfortably dry air the most?
To find out, HouseFresh used Weather Spark data to count the number of “dry air days” (days that had a dew point of 13°C (55°F) or below) that over 14,000 global cities and 5,000 U.S. cities experienced in 2023. Read on to discover the dry air capitals in the U.S., on every continent, and across the globe.
