January weather forecast
Oregon, USA

January is amongst the coldest months in Oregon, with the chill felt most prominently in the mountainous regions. The Cascade Mountains are particularly cold, with temperatures plunging to lows of 18°F (-7.8°C) and causing frigid conditions for the inhabitants and travelers alike. On the other hand, coastal regions offer a reprieve from the bitter cold, with temperatures registering in a more comfortable range, from 37°F (2.8°C) to 42°F (5.6°C).

Oregon's capital, Portland, serves as a noteworthy city in terms of climate during January. The city experiences a blend of both coastal and inland weather influences, often leading to wet and chilly conditions. Though snowfall isn't as prevalent in Portland as in the mountainous regions, the city can still see occasional snow, contributing to its wintry ambiance.

This month stands out for its significant snowfall in mountainous areas, especially the Cascade, Blue, and Wallowa ranges. The snow depth in these regions can be substantial, making January one of the prime months for winter sports enthusiasts seeking deep powder.

Comparatively, December often shares similar cold and wet conditions with January, but by the time February rolls around, there might be a marginal increase in temperatures, especially in the coastal regions. The overall weather pattern remains consistent, with January sandwiched between two of the coldest months in the Oregonian calendar.
