Hourly Pressure Trends
Track the barometric pressure in Roswell hour by hour and stay informed about how it will change over the next 6 hours.
Changes in weather patterns in Roswell cause barometric pressure to rise and fall. Atmospheric pressure increases when a high-pressure system moves in, and decreases when a low-pressure system arrives.
Roswell's elevation of about 360 feet above sea level and its hilly landscape affect atmospheric pressure. The surrounding hills can trap or redirect air masses, influencing pressure variations.
During winter, Roswell's pressure is usually higher due to cold, dense air. In summer, pressure is lower due to warm, rising air. Spring and fall bring moderate pressure with mild temperatures.
Roswell has a humid subtropical climate, causing barometric pressure to fluctuate more significantly. This leads to occasional extreme weather events and makes pressure changes more noticeable to residents.
