February goes down as 7th coldest at Sea-Tac

February goes down as 7th coldest at Sea-Tac

If it felt a little chilly this month, well, you would be right.

February just ended up with an average temperature of 39.25 degrees, making it the 7th coldest February at Sea-Tac Airport since 1948.

Here's where we ended up:

  1. 35.64 1956
  2. 35.88 1989
  3. 37.30 1949
  4. 38.20 1955
  5. 38.98 1985
  6. 39.00 1948
  7. 39.25 2011
  8. 39.50 1957

You can see a cold February is a signature of La Nina as almost every other year on that chart is from a L a Nina winter (and I only have data back to 1950, so it's possible '48 and '49 were too.)

Average temperature is taking the high and low for each day and averaging it out.

Here is how some other cities fared:
