Washington's Warmest December Ever? Breaking 2023's Record & Atmospheric Rivers Explained (2026)

Washington's Weather: A Warming Trend That's Hard to Ignore

The Pacific Northwest is experiencing a climate conundrum, with record-breaking warmth in December, despite predictions of a cold, wet winter.

It's a paradox that has left meteorologists and climate experts scratching their heads. Washington state is on course to have its warmest December ever recorded, surpassing the record set just last year in 2023. Steven Reedy, a meteorologist with the National Weather Service, predicts an average temperature of 45.9 degrees this month, edging out the previous record of 45.5 degrees.

But here's where it gets controversial: this warmth comes amidst a La Niña winter, typically associated with cooler temperatures. Forecasters predicted a wet winter for the Pacific Northwest, and they were right - December brought above-average rainfall to the Seattle area, largely due to three atmospheric rivers that caused devastating floods.

And this is the part most people miss: while the floods were catastrophic, they also helped Washington get back on track for its annual rainfall. The state is now just 0.18 inches shy of the average annual rainfall, a stark contrast to the severe drought conditions it faced this fall, which put it on course for one of the driest years on record.

Deputy State Climatologist Karin Bumbaco explains that the Yakima Basin, in particular, was severely affected by the drought, with some of the lowest water levels since 1971. But the recent rainfall, while causing floods, has also helped the basin increase its water storage and reduce the long-term precipitation deficit.

So, is this a sign of climate change? Or just a natural variation in weather patterns? The debate is sure to continue, but one thing is clear: Washington's weather is anything but ordinary.

What are your thoughts on this warming trend? Do you think it's a cause for concern, or just a blip on the radar? Share your opinions in the comments and let's discuss!
