Oregon has witnessed some remarkably warm Januarys over the years, and the latest data highlights the ten hottest Januarys on record, stirring up curiosity about our changing climate.
As we find ourselves in a winter season characterized by unusually mild weather and closed ski resorts, many residents of Oregon may be pondering the climatic shifts that affect their state. The last few years have shown a distinct trend towards warmer winters, making the question of what January will bring all the more pressing.
Take 2022, for example; it marked the third hottest July across the continental U.S. since records began in 1895, according to statistics from the National Oceanic and Atmospheric Administration. In that month alone, twenty states recorded one of their ten hottest days ever. Similarly, 2021 was globally recognized as the hottest month on record. Such data paints a concerning picture, as climate change increasingly contributes to rising temperatures and unprecedented heat waves. Since 1880, the Earth's average temperature has escalated by about 0.14 degrees Fahrenheit each decade, accumulating to nearly 2 degrees Fahrenheit overall.
In Portland specifically, December 2025 set a new benchmark for warmth, with an average temperature reaching 47.4 degrees—an astonishing six degrees higher than the typical figure. Throughout that month, temperatures dipped into the 30s only about a dozen times, and the year 2025 was tied with 2024 as Portland's second-warmest year, as reported by the National Weather Service. However, forecasts suggest that due to a weak La Niña effect, cooler-than-usual temperatures might linger through March.
To delve deeper into Oregon's climatic history, Stacker has compiled a list of the hottest Januarys in the state since 1895. This ranking is based on the highest average temperatures recorded each month, along with specific details such as statewide highs and lows, as well as total precipitation for each of these notably warm Januarys. Here’s a closer look at those top ten months:
- January 2003 (tie) - Average Temperature: 39°F; Monthly High: 45.8°F; Monthly Low: 32.2°F; Total Precipitation: 4.96 inches.
- January 1953 (tie) - Average Temperature: 39°F; Monthly High: 45.2°F; Monthly Low: 32.8°F; Total Precipitation: 9.19 inches.
- January 2015 - Average Temperature: 38.1°F; Monthly High: 46.3°F; Monthly Low: 29.9°F; Total Precipitation: 1.98 inches.
- January 1934 - Average Temperature: 37.9°F; Monthly High: 45°F; Monthly Low: 30.9°F; Total Precipitation: 4.26 inches.
- January 2018 - Average Temperature: 37.5°F; Monthly High: 44.6°F; Monthly Low: 30.4°F; Total Precipitation: 4.14 inches.
- January 2010 - Average Temperature: 36.9°F; Monthly High: 42.8°F; Monthly Low: 31°F; Total Precipitation: 4.52 inches.
- January 2014 - Average Temperature: 36.7°F; Monthly High: 45.9°F; Monthly Low: 27.5°F; Total Precipitation: 2.35 inches.
- January 1994 - Average Temperature: 36.5°F; Monthly High: 44.6°F; Monthly Low: 28.5°F; Total Precipitation: 3.12 inches.
- January 1983 - Average Temperature: 35.8°F; Monthly High: 42.7°F; Monthly Low: 29°F; Total Precipitation: 4.64 inches.
- January 1981 - Average Temperature: 35.7°F; Monthly High: 42.2°F; Monthly Low: 29.2°F; Total Precipitation: 2.21 inches.
As we analyze these figures, it's crucial to reflect on the implications of such temperature trends. The drastic rise in January temperatures can spark debates on climate responsibility and the actions needed to mitigate further changes. How do you feel about the evident warming patterns? Are they a wake-up call for action, or do you see them as part of a natural cycle? We’d love to hear your thoughts!
