Seattle – Coldest February in 30 years

4th coldest in 75 years

“Through the 16th of February, Seattle is 8 degrees F below normal for the month,” says reader Chuck Clancy. “This is the 4th coldest first 16 days of February in the 75 years of records at Sea-Tac airport and the coldest in the last 30 years. The 3 years that were colder were 1989, 1949 and 1956.”

“This is according to the 3am discussion yesterday morning from the Seattle forecast office.”

“I bet they won’t publish it, but it really says it all,” says

  1. When one sees or hears a temperature report for Seattle, it actually refers to the large airport well south of the southern city limits. Sea-Tac Intl Airport logged over 430,000 takeoffs and landings in 2018. The location of the FAA/NWS ASOS at Sea-Tac Airport is adjacent to a taxiway located between two of the runways. At 1245 PST today, KSEA reports 43F, and closer to my home a local CWOP observer about 8.5 miles due east of KSEA reports 38F. But, we are assured a steady stream of jet exhaust blasting the runways and the heat from the physical plant or pavement does not impact temperature readings. It takes a lot of cold to impact records at Sea-Tac airport aka “Seattle.”

    • Much like the Northern Runway at Heathrow during a southerly light flow of air and the runway being used for landings from the east it inflates the Summer tempretures by over 4C

      • Should have posted the above into Windsong’s post. But John it’s the only heat source we have, what cruel isn’t the Sun but the changing wave forms of the Earth Jet Streams.
        These bring the various climates and weather dependent on the seasons and the Sun cycles various cycles of energy output.
        For example:
        1949 2 yrs. from SM on the rise to MAX one of the worst worldwide NH winters for nearly 100 yrs. During the SM period between SC18 and SC19
        1956 SM of SC18
        1989 2 yrs. Before SM between SC21 and SC23
        Each of these examples are during periods of very low UV, and significant solar coronial holes activity which leads to blocking SAW events and reversals of the PDO and NAO.

        Its UV and EUV which controls our climate and not the lagging trace gas CO2.

  2. Grew up in Seattle.
    Remember reading once that back in the early part of the 20th century it got so cold that ice actually formed in Puget Sound.
    Now that I’d like to see.
