Logan has a humid continental climate with
hot though usually dry summers and cold winters with moderate snowfall.
Precipitation tends to be heaviest in the spring months. Similar to other areas
in northern Utah, during mid-winter high pressure systems often situate
themselves over Cache Valley, leading to strong temperature inversions. These
temperature inversions trap cold air and pollutants and allow thick smog to
accumulate in the valley for several days to weeks at a time
