Hourly Pressure Trends
Track the barometric pressure in Sisters hour by hour and stay informed about how it will change over the next 6 hours.
Sisters, Oregon has a high-desert climate, which means low air pressure. This is because the area is close to the Pacific Ocean, which brings moist air that rises and cools, making the air pressure drop.
The nearby mountains, like the Cascades, block some of this moist air, causing it to rise and cool even more, making the air pressure drop further.
In winter, cold air from the north brings even lower pressure, making it rain and snow. In summer, warm air from the south brings higher pressure, making it dry and sunny.
The high-desert climate means Sisters has big pressure changes between seasons, with low pressure in winter and high pressure in summer, making the weather change a lot.
