Portland - Recent March Temperatures, Rain & Snow

The numbers here describe what the March weather in Portland, Oregon was like for every year since 2010. A series of tables gives March 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 March. 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.

The climate data come from weather measurements made at the Weather Forecast Office near downtown Portland.
