Portland - Recent January Temperatures, Rain & Snow





The numbers here describe what the January weather in Portland, Oregon was like for every year since 2010. A series of tables gives January data by year for temperature, precipitation and snowfall.

They begin with average maximum and minimum temperatures in degrees Fahrenheit and Celsius. That's followed by how many hot or cold days occurred each January. Then there's information on how much rain and snow actually landed this month during recent years, as well as how often Portland had wet or snowy weather.
